WIP

Currently a bit stuck on getting the IPMask to `nebula.NewHostCert`.
Probably the best way would be to limit number of CIDRs to just 1 for
now, and include that in the `nebula.CACert`. Or maybe we can just
provide a way to parse it out of the `ca.crt`. Either way CIDRs should
get removed from `admin.CreationParams`.

-                    GNU AFFERO GENERAL PUBLIC LICENSE
-                       Version 3, 19 November 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The GNU Affero General Public License is a free, copyleft license for
-software and other kinds of works, specifically designed to ensure
-cooperation with the community in the case of network server software.
-
-  The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works.  By contrast,
-our General Public Licenses are intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
-  Developers that use our General Public Licenses protect your rights
-with two steps: (1) assert copyright on the software, and (2) offer
-you this License which gives you legal permission to copy, distribute
-and/or modify the software.
-
-  A secondary benefit of defending all users' freedom is that
-improvements made in alternate versions of the program, if they
-receive widespread use, become available for other developers to
-incorporate.  Many developers of free software are heartened and
-encouraged by the resulting cooperation.  However, in the case of
-software used on network servers, this result may fail to come about.
-The GNU General Public License permits making a modified version and
-letting the public access it on a server without ever releasing its
-source code to the public.
-
-  The GNU Affero General Public License is designed specifically to
-ensure that, in such cases, the modified source code becomes available
-to the community.  It requires the operator of a network server to
-provide the source code of the modified version running there to the
-users of that server.  Therefore, public use of a modified version, on
-a publicly accessible server, gives the public access to the source
-code of the modified version.
-
-  An older license, called the Affero General Public License and
-published by Affero, was designed to accomplish similar goals.  This is
-a different license, not a version of the Affero GPL, but Affero has
-released a new version of the Affero GPL which permits relicensing under
-this license.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU Affero General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Remote Network Interaction; Use with the GNU General Public License.
-
-  Notwithstanding any other provision of this License, if you modify the
-Program, your modified version must prominently offer all users
-interacting with it remotely through a computer network (if your version
-supports such interaction) an opportunity to receive the Corresponding
-Source of your version by providing access to the Corresponding Source
-from a network server at no charge, through some standard or customary
-means of facilitating copying of software.  This Corresponding Source
-shall include the Corresponding Source for any work covered by version 3
-of the GNU General Public License that is incorporated pursuant to the
-following paragraph.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the work with which it is combined will remain governed by version
-3 of the GNU General Public License.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU Affero General Public License from time to time.  Such new versions
-will be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU Affero General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU Affero General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU Affero General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU Affero General Public License as published by
-    the Free Software Foundation, either version 3 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU Affero General Public License for more details.
-
-    You should have received a copy of the GNU Affero General Public License
-    along with this program.  If not, see <https://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
-  If your software can interact with users remotely through a computer
-network, you should also make sure that it provides a way for users to
-get its source.  For example, if your program is a web application, its
-interface could display a "Source" link that leads users to an archive
-of the code.  There are many ways you could offer source, and different
-solutions will be better for different programs; see section 13 for the
-specific requirements.
-
-  You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU AGPL, see

-# Isle
+# cryptic-net
 
-Welcome to Isle's technical documentation. You can find a less technical
-entrypoint to Isle on [the Micropelago website][isle].
+The cryptic-net project provides the foundation for an **autonomous community
+cloud infrastructure**.
 
-Isle runs on a host as a server daemon, and connects to other isle instances to
-form a peer-to-peer network. Isle networks are completely self-hosted; no
-third-parties are required for a network to function.
+This project targets communities of individuals, where certain members of the
+community would like to host services and applications from servers running in
+their homes or offices. These servers can range from simple Raspberry Pis to
+full-sized home PCs.
 
-Members of a network are able to build upon the capabilities provided by Isle to
-host services for themselves and others. These capabilities include:
+The core components of cryptic-net, currently, are:
 
-* A VPN which enables direct peer-to-peer communication between network members.
-  Even if most hosts in the network are on a private LAN (e.g. their home WiFi
-  network) or have a dynamic IP, they can still communicate directly with each
-  other.
+* A VPN which enables direct peer-to-peer communication. Even if most hosts in
+  the network are on a private LAN (e.g. their home WiFi network) or have a
+  dynamic IP, they can still communicate directly with each other.
 
-* An S3-compatible network filesystem. Each member can provide as much storage
-  as they care to, if any. Stored data is sharded and replicated across all
-  hosts that choose to provide storage.
+* An S3-compatible network filesystem. Each participant can provide as much
+  storage as they care to, if any. Stored data is sharded and replicated across
+  all hosts that choose to provide storage.
 
-* A DNS server which provides automatic host discovery within the network.
+These components are wrapped into a single binary, with all setup being
+automated. cryptic-net takes "just works" very seriously.
 
-Every isle daemon is able to create or join multiple independent networks. In
-this case the networks remain siloed from each other, such that members of one
-network are unable to access resources or communicate with members of the other.
+Participants are able to build upon these foundations to host services for
+themselves and others. They can be assured that their communications are private
+and their storage is reliable, all with zero administrative overhead and zero
+third parties involved.

-## Getting Started
+## Documentation
 
-The following pages will guide you through setup of Isle, joining an existing
-network, and all other functionality available via the command-line.
+_NOTE: There is currently only a single live cryptic-net which can be joined,
+though generalizing the bootstrap process so others can create their own network
+is [planned][roadmap]. If you do not know the admins of this cryptic-net then
+unfortunately there's not much you can do right now._
 
-* [Installation](./docs/install.md)
-* [Command-line Usage](./docs/command-line.md)
-    * [Join a Network](./docs/user/join-a-network.md)
+cryptic-net users fall into different roles, depending on their level of
+involvement and expertise within their particular network. The documentation for
+cryptic-net is broken down by these categories, so that the reader can easily
+know which documents they need to care about.
 
-Those who want to dive in and contribute to the Isle codebase should check out
-the [Developer Documentation](./docs/dev/index.md).
+### User Docs
+
+Users are participants who use cryptic-net resources, but do not provide any
+network or storage resources themselves. Users may be accessing the network from
+a laptop, and so are not expected to be online at any particular moment.
+
+Documentation for users:
+
+* [Getting Started](docs/user/getting-started.md)
+* [Creating a daemon.yml File](docs/user/creating-a-daemonyml-file.md)
+* [Using DNS](docs/user/using-dns.md) (advanced)
+* Restic example (TODO)
+
+### Operator Docs
+
+Operators are participants who own a dedicated host which they can expect to be
+always-online (to the extent that's possible in a residential environment).
+Operator hosts will need at least one of the following to be useful:
+
+* A static public IP, or a dynamic public IP with [dDNS][ddns] set up.
+
+* At least 100GB of unused storage which can be reserved for the network.
+
+Operators are expected to be familiar with server administration, and to not be
+afraid of a terminal.
+
+Documentation for operators:
+
+* [Contributing Storage](docs/operator/contributing-storage.md)
+* [Contributing a Lighthouse](docs/operator/contributing-a-lighthouse.md)
+* [Managing garage](docs/operator/managing-garage.md)
+
+[ddns]: https://www.cloudflare.com/learning/dns/glossary/dynamic-dns/
+
+### Admin Docs
+
+Admins are participants who control membership within the network. They are
+likely operators as well.
+
+Documentation for admins:
+
+* [Adding a Host to the Network](docs/admin/adding-a-host-to-the-network.md)
+* Removing a Host From the Network (TODO)
+
+### Dev Docs
+
+Dev may or may not be participants in any particular cryptic-net. They instead
+are those who work on the actual code for cryptic-net.
+
+Documentation for devs:
+
+* [Design Principles](docs/dev/design-principles.md)
+* [`cryptic-net daemon` process tree](docs/dev/daemon-process-tree.svg): Diagram
+  describing the [pmux](https://github.com/cryptic-io/pmux) process tree created
+  by `cryptic-net daemon` at runtime.
+* [Rebuilding Documentation](docs/dev/rebuilding-documentation.md)
+
+## Misc
+
+Besides documentation, there are a few other pages which might be useful:
+
+* [Roadmap][roadmap]

-# Creating a New Network
-
-This guide is for those who wish to start a new isle network of their own.
-
-By starting a new isle network, you are becoming the administrator of a
-network. Be aware that being a network administrator is not necessarily easy,
-and the users of your network will frequently need your help in order to have a
-good experience. It can be helpful to have others with which you are
-administering the network, in order to share responsibilities.
-
-## Requirements
-
-Creating a network is done using a single host, which will become the first host
-in the network.
-
-The configuration used during network creation will be identical to that used
-during normal operation of the host, so be prepared to commit to that
-configuration for a non-trivial amount of time.
-
-The requirements for this host are:
-
-* A public static IP, or a dynamic public IP with [dDNS][ddns] set up.
-
-  * There should be UDP port which is accessible publicly over that IP/DNS name.
-    This may involve forwarding the UDP port in your gateway if the host is
-    behind a NAT, and/or allowing traffic on that UDP port in your hosts
-    firewall.
-
-* At least 3 GB of disk storage space.
-
-  * At least 3 directories should be chosen, each of which will be committing at
-    least 1GB. Ideally these directories should be on different physical disks,
-    but if that's not possible it's ok. See the Next Steps section.
-
-* None of the resources being used for this network (the UDP port or storage
-  locations) should be being used by other networks.
-
-## Step 1: Configure the isle Daemon
-
-Open `/etc/isle/daemon.yml` in a text editor and perform the following changes:
-
-* Set the `vpn.public_addr` field to the `host:port` your host is accessible on,
-  where `host` is the static public IP/DNS name of your host, and `port` is the
-  UDP port which is publicly accessible.
-
-* Configure 3 (at least) allocations in the `storage.allocations` section.
-
-Save and close the file.
-
-Run the following to restart the daemon with the new configuration:
-
-```
-sudo systemctl restart isle
-```
-
-## Step 2: Choose Parameters
-
-There are some key parameters which must be chosen when creating a new network.
-These will remain constant throughout the lifetime of the network, and so should
-be chosen with care.
-
-* Name: A human-readable name for the network. This will only be used for
-  display purposes.
-
-* Subnet: The IP subnet (or CIDR) will look something like `10.10.0.0/16`, where
-  the `/16` indicates that all IPs from `10.10.0.0` to `10.10.255.255` are
-  included. It's recommended to choose from the [ranges reserved for private
-  networks](https://en.wikipedia.org/wiki/IPv4#Private_networks), but within
-  that selection the choice is up to you.
-
-* Domain: isle is shipped with a DNS server which will automatically
-  configure itself with all hosts in the network, with each DNS entry taking the
-  form of `hostname.hosts.domain`, where `domain` is the domain chosen in this
-  step. The domain may be a valid public domain or not, it's up to you.
-
-* Hostname: The hostname of your host, which will be the first host in the
-  network, must be chosen at this point. You can reference the [Adding a Host to
-  the Network](./adding-a-host-to-the-network.md) document for the constraints
-  on the hostname.
-
-* IP: The IP of your host, which will be the first host in the network. This IP
-  must be within the chosen subnet range.
-
-## Step 3: Create the Network
-
-To create the network, run:
-
-```
-sudo isle network create \
-    --name <name> \
-    --ip-net <subnet> \
-    --domain <domain> \
-    --hostname <hostname>
-```
-
-At this point your host, and your network, are ready to go! To add other hosts
-to the network you can reference the [Adding a Host to the Network][add-host]
-document.

-# Removing a Host from the Network
-
-Removing a host from the network is as simple as
-
-```
-isle host remove --hostname <name>
-```
-
-Keep in mind that if the host being removed had storage allocations set on it
-then the network will require some time to rebalance the stored data across the
-remaining storage hosts. This means that when removing multiple storage hosts
-from the network it is a good idea to wait a while in between each removal.

-Operators are members who own a dedicated host which they can expect to be
-always-online (to the extent that's possible in a residential environment).
-Operator hosts will need at least one of the following to be useful:
-
-* A static public IP, or a dynamic public IP with [dDNS][ddns] set up.

-# Architecture
-
-The isle daemon is the central point around which all operations occur. Users of
-the isle command-line tool (or, soon, a GUI) communicate with the daemon over a
-local RPC socket to issue commands, for example to tell it to join a new network
-or to retrieve the names of hosts in an already-joined network.
-
-For every network which is joined, the isle daemon will create and manage
-sub-processes to provide certain parts of its functionality. These include:
-
-* A [nebula][nebula] instance to provide VPN functionality.
-* A [dnsmasq][dnsmasq] instance to act as DNS server.
-* Zero or more [garage][garage] instances, depending on how storage is
-  configured on the host, to provide the S3 storage layer.
-
-The isle daemon considers the configuration and management of these
-sub-processes to be an implementation detail. In other words, its RPC interface,
-and therefore all user interfaces, do not expose members to the fact that these
-sub-processes exist, or even that these projects are being used under the hood.

-
-(*NOTE* The first time you run some of these builds a lot of things will be
-built from scratch. If you have not otherwise configured it, nix might be using
-a tmpfs as its build directory, and the capacity of this tmpfs will probably be

-[tmpdir-gh]: https://github.com/NixOS/nix/issues/2098#issuecomment-383243838
-
-## Current System
-
-You can build an AppImage for your current system by running the following from
-the project's root:
-
-```
-nix-build -A build.appImage
-```
-
-The resulting binary can be found under `result/bin`.
-
-## Cross-Compile
-
-An AppImage can be cross-compiled by passing the `hostSystem` argument:
-
-```
-nix-build --argstr hostSystem "x86_64-linux" -A build.appImage
-```
-
-Supported system strings are enumerated in `nix/pkgs.nix`.
-
-## Alternative Build Targets
-
-Besides AppImage, Isle supports building alternative package types which are
-targetted at different specific operating systems. Each of these has its own
-`build.*` target.
-
-* AppImage (all OSs): `nix-build -A build.appImage`
-* Arch Linux package: `nix-build -A build.archPkg`
-
-All targets theoretically support passing in a `hostSystem` argument to
-cross-compile to a different architecture or OS, but some targets may not make
-sense with some `hostSystem` values.

-# Releases
-
-A release consists of:
-
-- A full set of `isle` binaries for all supported platforms, compiled from the
-  same source.
-- A text file containing hashes of each binary.
-- A file containing a signature of the hash file, created by whoever is building
-  the release.
-
-## Building
-
-*NOTE: This has only been tested from an x86_64 linux machine*
-
-To create a release only a functional nix installation is required. Simply run
-the `./release.sh` script, and input a release name when prompted.
-
-From here an `isle` binary will be cross-compiled for all supported
-platforms. This will take a long time the first time you perform it on your
-machine.
-
-Once compilation is completed, the release will be signed using the default GPG
-key on your machine, and you will be prompted for its password in order to
-create the signature.
-
-## Releasing
-
-Releases are uploaded to the repository's Releases page, and release naming
-follows the conventional semantic versioning system. Each release should be
-accompanied by a set of changes which have occurred since the last release,
-described both in the `CHANGELOG.md` file and in the description on the Release
-itself.

-Integration tests are those which require processes or state external to the
-test itself. Integration tests are marked using the
-`toolkit.MarkIntegrationTest` function, which will cause them to be skipped

-
-Besides a normal nix installation (like all Isle development needs), integration
-tests also require `sudo` and [capsh][capsh] to be installed on the system.

-## Install isle
-
-How isle gets installed depends on which Linux distribution you are using.
-
-### Archlinux (also Manjaro)
-
-Download the latest `.pkg.tar.zst` package file for your platform from
-[this link][latest].
-
-Install the package using pacman:
-
-```
-sudo pacman -U /path/to/isle-*.pkg.tar.zst
-```
-
-### Other Distributions
-
-If a package file is not available for your distribution you can still install
-an AppImage directly. It is assumed that all commands below are run as root.
-
-Download the latest `.AppImage` binary for your platform from
-[this link][latest], and place it in your `/usr/bin` directory.
-
-Create a `daemon.yml` file using default values by doing:
-```
-mkdir -p /etc/isle/
-isle daemon --dump-config > /etc/isle/daemon.yml
-```
-
-Create a system user for the isle daemon to run as:
-```
-useradd -r -s /bin/false -C "isle Daemon" isle
-```
-
-If your distro uses systemd, download [the latest systemd service
-file][serviceFile] and place it in `/etc/systemd/system`. Run `systemctl
-daemon-reload` to ensure systemd has seen the new service file.
-
-If your distro uses an init system other than systemd then you will need to
-configure that yourself. You can use the systemd service file linked above as a
-reference.

-
-### From Source
-
-If you'd like to build your own `isle` binary from scratch, see the [Building
-Isle](./dev/building.md) document.
-
-## Add Users to the `isle` Group (Optional)
-
-If you wish to run isle commands as a user other than root, you can add that
-user to the `isle` group:
-
-```
-sudo usermod -aG isle username
-```
-
-## Start the isle Service
-
-Once installed and bootstrapped you can enable and start the isle service by
-doing:
-
-```
-sudo systemctl enable --now isle
-```

-# Firewalls
-
-When providing services on your host, whether

-This means that you only need to configure the VPN firewall if you are hosting

-
-## Host Firewall
-
-The host you are running isle on will almost definitely have a firewall
-running, separate from the VPN firewall. If you wish to provide services for

-If you don't feel comfortable allowing nebula to deal with all packet filtering,

+# Roadmap
+
+The following are rough outlines of upcoming work on the roadmap, roughly in the
+order they will be implemented.
+
+## Main quest
+
+These items are listed more or less in the order they need to be completed, as
+they generally depend on the items previous to them.
+
+### Cross Compilation
+
+Currently the only supported OS/CPU is Linux/amd64. This can be expanded
+_theoretically_ quite easily, using nix's cross compilation tools. First target
+should be OSX/arm64, but windows would also be quite the get.
+
+### Bootstrap
+
+This will be difficult. There's currently no way to bootstrap a new cryptic-net
+network from scratch, only the currently existing one is supported. Support for
+IPv6 internal CIDR should also be a part of this effort.
+
+### Testing
+
+Once bootstrap is generalized, we'll be able to write some automated tests.
+
+## Side quests
+
+These items aren't necessarily required by the main quest, and aren't dependent
+on any other items being completed. They are nice-to-haves that we do want to
+eventually complete, but aren't the main focus.
+
+### DNS resolver settings
+
+The daemon should update the resolver settings of the host, so that it
+automatically serves DNS queries, unless set to not do so in `daemon.yml`.
+
+### Install sub-command
+
+It would be great to have a `cryptic-net install` sub-command which would
+auto-detect the installed operating system and install the daemon automatically.
+
+### Web server + interface
+
+One idea is to have every `cryptic-net daemon` run a webserver as one of its
+sub-processes. This server could serve multiple functions:
+
+- Possible public gateway, if the host is configured to be public, into internal
+  cryptic-net services. This will require some sort of service discovery
+  mechanism that other hosts in the network can easily hook into via their
+  `daemon.yml`s. Ideally this mechanism would involve little beyond updating
+  entries in garage, which the public gateways then pick up on.
+
+  One wrinkle here will be TLS certificates. Ideally internal hosts could host
+  websites publicly via the gateways on their network, using arbitrary domains
+  that the users own. The gateways will need some way of obtaining certs for
+  these domains automatically (or as automatically as possible).
+
+- Local interface for the `cryptic-net daemon` process. For example, status and
+  connectivity information for the local host could be provided via a simple web
+  interface, which the user can open in their browser. This saves us the effort
+  of needing to develop UIs for individual OSs. This could also make remotely
+  debugging hosts easier for admins.
+
+### Mobile app
+
+To start with a simple mobile app which provided connectivity to the network
+would be great. Such a mobile app could be based on the existing
+[mobile_nebula](https://github.com/DefinedNet/mobile_nebula). The main changes
+needed would be:
+
+- Allow importing a `bootstrap.tgz` file, rather than requiring manual setup by
+  users.
+
+- Set device's DNS settings. There is an [open
+  PR](https://github.com/DefinedNet/mobile_nebula/pull/18) for android to do
+  this upstream.
+
+- Rebranding and possibly submitting to Apple app store (bleh).
+
+### Don't run as root
+
+It's currently a pretty hard requirement for `cryptic-net daemon` to run as
+root. This is due to:
+
+- nebula's network interface root to be started.
+
+- dnsmasq listening on port 53, generally a protected port.
+
+If we can't figure out how to get these things running from the start as
+non-privileged users, we at least need to get cryptic-net to drop priveleges
+from root after initial startup.
+
+### Plugins
+
+It would not be difficult to spec out a plugin system using nix commands.
+Existing components could be rigged to use this plugin system, and we could then
+use the system to add future components which might prove useful. Once the
+project is public such a system would be much appreciated I think, as it would
+let other groups rig their binaries with all sorts of new functionality.

+# Creating a daemon.yml File
+
+The `cryptic-net daemon` process has generally sane defaults and does not need
+to be configured for most users. However, in some cases it does, so this
+document describes how to use the `daemon.yml` file to handle those cases.
+
+## Create daemon.yml
+
+First, create a `daemon.yml` file. You can create a new `daemon.yml` with
+default values filled in by doing:
+
+```
+cryptic-net daemon --dump-config > /path/to/daemon.yml
+```
+
+If you open that file in a text editor you can view all default values that
+`cryptic-net daemon` ships with, as well as documentation for all configurable
+parameters. Feel free to edit this file as needed.
+
+## Using daemon.yml
+
+With the `daemon.yml` created and configured, you can configure your daemon
+process to use it by passing it as the `-c` argument:
+
+```
+sudo cryptic-net daemon -c /path/to/daemon.yml
+```
+
+If you are an operator then your host should be running its `cryptic-net daemon`
+process in systemd (see [Getting Started](getting-started.md) if
+not), and you will need to modify the `cryptic-net.service` accordingly.

+# Getting Started
+
+This document will guide you through the process of obtaining a cryptic-net
+binary and joining the network.
+
+NOTE currently only linux machines with amd64/x86_64 processors are supported.
+More OSs and architectures coming soon!
+
+## Obtaining a cryptic-net Binary
+
+Every host can have a binary built for it which has all configuration for that
+host embedded directly into it. Such binaries require no extra configuration by
+the user to use, and have no dependencies on anything else in the user's system.
+
+The process of obtaining a custom binary for your host is quite simple: ask an
+admin of the network you'd like to join to give you one!
+
+Note that if you'd like to join the network on multiple devices, each device
+will needs its own binary, so be sure to tell your admin how many you want to
+add and their names.
+
+### Obtaining a cryptic-net Binary, the Hard Way
+
+Alternatively, you can build your own binary by running the following from the
+project's root:
+
+```
+nix-build -A appImage
+```
+
+(*NOTE* Dependencies of `cryptic-net` seemingly compile all of musl and rust
+from scratch (it's not clear why, blame garage!). If you have not otherwise
+configured it, nix might be using a tmpfs as its build directory, and the
+capacity of this tmpfs will probably be exceeded by this build. You can change
+your build directory to somewhere on-disk by setting the TMPDIR environment
+variable for `nix-daemon` (see [this github issue][tmpdir-gh].))
+
+The resulting binary can be found in the `result` directory which is created.
+
+In this case you will need an admin to provide you with a `bootstrap.tgz` for
+your host, rather than a custom binary. When running the daemon in the following
+steps you will need to provide the `--bootstrap-path` CLI argument to the daemon
+process.
+
+[tmpdir-gh]: https://github.com/NixOS/nix/issues/2098#issuecomment-383243838
+
+## Running the Daemon
+
+Once you have a binary, you will need to run the `daemon` sub-command as the
+root user. This can most easily be done using the `sudo` command, in a terminal:
+
+```
+sudo /path/to/cryptic-net daemon
+```
+
+This will start the daemon process, which will keep running until you kill it
+with `ctrl-c`.
+
+You can double check that the daemon is running properly by pinging a private IP
+from the network in a separate terminal:
+
+```
+ping 10.10.0.1
+```
+
+If the pings are successful then your daemon is working!
+
+## Installing the Daemon as a Systemd Service
+
+NOTE in the future we will introduce an `install` sub-command which will
+automate most of this section.
+
+Rather than running the daemon manually, you can install it as a systemd
+service. This way your daemon will automatically start in the background on
+startup, and will be restarted if it has any issues.
+
+To do so, create a file at `/etc/systemd/system/cryptic-net.service` with the
+following contents:
+
+```
+[Unit]
+Description=cryptic-net
+Requires=network.target
+After=network.target
+
+[Service]
+Restart=always
+RestartSec=1s
+User=root
+ExecStart=/path/to/cryptic-net daemon
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Remember to change the `/path/to/cryptic-net` part to the actual absolute path
+to your binary!
+
+Once created, perform the following commands in a terminal to enable the
+service:
+
+```
+sudo systemctl daemon-reload
+sudo systemctl enable --now cryptic-net
+```
+
+You can check the service's status by doing:
+
+```
+sudo systemctl status cryptic-net
+```
+
+and you can view its full logs by doing:
+
+```
+sudo journalctl -lu cryptic-net

 # Using DNS
 
-Every `isle daemon` process ships with a DNS server which runs
+Every `cryptic-net daemon` process ships with a DNS server which runs
 automatically. This server will listen on port 53 on the VPN IP of that
 particular host.
 
-The server will serve requests for `<hostname>.hosts.<domain>` hostnames,
-where `<hostname>` is the name of any host in the network, and `<domain`> is the
-network's domain name.
+The server will serve requests for `<hostname>.hosts.cryptic.io` hostnames,
+where `<hostname>` is any host's name in the `bootstrap/nebula/hosts` directory.
+The returned IP will be the corresponding IP for the host, as listed in the
+host's `bootstrap/nebula/hosts` file.
 
-If a request for a hostname not within the network's domain is received then the
-server will forward the request to a pre-configured public resolver. The set of
-public resolvers used can be configured in the `/etc/isle/daemon.yml` file.
+If a request for a non `.cryptic.io` hostname is received then the server will
+forward the request to a pre-configured public resolver. The set of public
+resolvers used can be configured using the
+[daemon.yml](creating-a-daemonyml-file.md) file.

+This DNS server is an optional feature of cryptic-net, and not required in
+general for making use of the network.
 
 ## Example
 
 As an example of how to make use of this DNS server, let's say my host's IP on
-the network is `10.10.1.1`, and my network's domain is `cool.internal`.
-In order to configure the host to use the isle DNS server for all DNS
-requests, I could do something like this:
+the network is `10.10.1.1`. In order to configure the host to use the
+cryptic-net DNS server for all DNS requests, I could do something like this:
 
 ```
 sudo su
 echo "nameserver 10.10.1.1" > /etc/resolv.conf
 ```
 
-From that point, all DNS requests on my host would hit the isle DNS
-server. If I request `my-host.hosts.cool.internal`, it would respond with the
-appropriate private IP.
+From that point, all DNS requests on my host would hit the cryptic-net DNS
+server. If I request `my-host.cryptic.io`, it would respond with the appropriate
+private IP.
 
 NOTE that configuration of dns resolvers is very OS-specific, even amongst Linux
 distributions, so ensure you know how your resolver configuration works before
