[Acknowledgments](#ack) + +### <a name="intro"/> Introduction + +BIND (Berkeley Internet Name Domain) is a complete, highly portable +implementation of the DNS (Domain Name System) protocol. + +The BIND name server, `named`, is able to serve as an authoritative name +server, recursive resolver, DNS forwarder, or all three simultaneously. It +implements views for split-horizon DNS, automatic DNSSEC zone signing and +key management, catalog zones to facilitate provisioning of zone data +throughout a name server constellation, response policy zones (RPZ) to +protect clients from malicious data, response rate limiting (RRL) and +recursive query limits to reduce distributed denial of service attacks, +and many other advanced DNS features. BIND also includes a suite of +administrative tools, including the `dig` and `delv` DNS lookup tools, +`nsupdate` for dynamic DNS zone updates, `rndc` for remote name server +administration, and more. + +BIND 9 began as a complete re-write of the BIND architecture that was +used in versions 4 and 8. Internet Systems Consortium +([https://www.isc.org](https://www.isc.org)), a 501(c)(3) public benefit +corporation dedicated to providing software and services in support of the +Internet infrastructure, developed BIND 9 and is responsible for its +ongoing maintenance and improvement. BIND is open source software +licensed under the terms of the Mozilla Public License, version 2.0. + +For a summary of features introduced in past major releases of BIND, +see the file [HISTORY](HISTORY.md). + +For a detailed list of changes made throughout the history of BIND 9, see +the file [CHANGES](CHANGES). See [below](#changes) for details on the +CHANGES file format. + +For up-to-date versions and release notes, see +[https://www.isc.org/download/](https://www.isc.org/download/). + +For information about supported platforms, see the +["Supported Platforms"](doc/arm/platforms.rst) section in the BIND 9 +Administrator Reference Manual. + +### <a name="help"/> Reporting bugs and getting help + +To report non-security-sensitive bugs or request new features, you may +open an Issue in the BIND 9 project on the +[ISC GitLab server](https://gitlab.isc.org) at +[https://gitlab.isc.org/isc-projects/bind9](https://gitlab.isc.org/isc-projects/bind9). + +Please note that, unless you explicitly mark the newly created Issue as +"confidential", it will be publicly readable. Please do not include any +information in bug reports that you consider to be confidential unless +the issue has been marked as such. In particular, if submitting the +contents of your configuration file in a non-confidential Issue, it is +advisable to obscure key secrets: this can be done automatically by +using `named-checkconf -px`. + +If the bug you are reporting is a potential security issue, such as an +assertion failure or other crash in `named`, please do *NOT* use GitLab to +report it. Instead, send mail to +[security-officer@isc.org](mailto:security-officer@isc.org) using our +OpenPGP key to secure your message. (Information about OpenPGP and links +to our key can be found at +[https://www.isc.org/pgpkey](https://www.isc.org/pgpkey).) Please do not +discuss the bug on any public mailing list. + +For a general overview of ISC security policies, read the Knowledge Base +article at [https://kb.isc.org/docs/aa-00861](https://kb.isc.org/docs/aa-00861). + +Professional support and training for BIND are available from +ISC at [https://www.isc.org/support](https://www.isc.org/support). + +To join the __BIND Users__ mailing list, or view the archives, visit +[https://lists.isc.org/mailman/listinfo/bind-users](https://lists.isc.org/mailman/listinfo/bind-users). + +If you're planning on making changes to the BIND 9 source code, you +may also want to join the __BIND Workers__ mailing list, at +[https://lists.isc.org/mailman/listinfo/bind-workers](https://lists.isc.org/mailman/listinfo/bind-workers). + +### <a name="contrib"/> Contributing to BIND + +ISC maintains a public git repository for BIND; details can be found +at [http://www.isc.org/git/](http://www.isc.org/git/). + +Information for BIND contributors can be found in the following files: +- General information: [CONTRIBUTING.md](CONTRIBUTING.md) +- Code of Conduct: [CODE_OF_CONDUCT.md](CODE_OF_CONDUCT.md) +- BIND 9 code style: [doc/dev/style.md](doc/dev/style.md) +- BIND architecture and developer guide: [doc/dev/dev.md](doc/dev/dev.md) + +Patches for BIND may be submitted as +[merge requests](https://gitlab.isc.org/isc-projects/bind9/merge_requests) +in the [ISC GitLab server](https://gitlab.isc.org) at +at [https://gitlab.isc.org/isc-projects/bind9/merge_requests](https://gitlab.isc.org/isc-projects/bind9/merge_requests). + +By default, external contributors don't have ability to fork BIND in the +GitLab server, but if you wish to contribute code to BIND, you may request +permission to do so. Thereafter, you can create git branches and directly +submit requests that they be reviewed and merged. + +If you prefer, you may also submit code by opening a +[GitLab Issue](https://gitlab.isc.org/isc-projects/bind9/issues) and +including your patch as an attachment, preferably generated by +`git format-patch`. + +### <a name="features"/> BIND 9.16 features + +BIND 9.16 is the current stable branch of BIND 9. It includes all +changes from the 9.15 development branch, updating the previous stable +branch, 9.14. New features include: + +* New `dnssec-policy` statement to configure a key and signing policy + for zones, enabling automatic key regeneration and rollover. +* New network manager based on `libuv`. +* Added support for the new GeoIP2 geolocation API, `libmaxminddb`. +* Improved DNSSEC trust anchor configuration using the `trust-anchors` + statement, permitting configuration of trust anchors in DS as well as + DNSKEY format. +* YAML output for `dig`, `mdig`, and `delv`. + +### <a name="build"/> Building BIND + +For information about building BIND 9, see the +["Building BIND 9"](doc/arm/build.rst) section in the BIND 9 +Administrator Reference Manual. + +### <a name="testing"/> Automated testing + +A system test suite can be run with `make test`. The system tests require +you to configure a set of virtual IP addresses on your system (this allows +multiple servers to run locally and communicate with one another). These +IP addresses can be configured by running the command +`bin/tests/system/ifconfig.sh up` as root. + +Some tests require Perl and the `Net::DNS` and/or `IO::Socket::INET6` modules, +and will be skipped if these are not available. Some tests require Python +and the `dnspython` module and will be skipped if these are not available. +See bin/tests/system/README for further details. + +Unit tests are implemented using the [CMocka unit testing framework](https://cmocka.org/). +To build them, use `configure --with-cmocka`. Execution of tests is done +by the [Kyua test execution engine](https://github.com/jmmv/kyua); if the +`kyua` command is available, then unit tests can be run via `make test` +or `make unit`. + +### <a name="doc"/> Documentation + +The *BIND 9 Administrator Reference Manual* is included with the source +distribution, in DocBook XML, HTML, and PDF format, in the `doc/arm` +directory. + +Some of the programs in the BIND 9 distribution have man pages in their +directories. In particular, the command line options of `named` are +documented in `bin/named/named.8`. + +Frequently (and not-so-frequently) asked questions and their answers +can be found in the ISC Knowledge Base at +[https://kb.isc.org](https://kb.isc.org). + +Additional information on various subjects can be found in other +`README` files throughout the source tree. + +### <a name="changes"/> Change log + +A detailed list of all changes that have been made throughout the +development BIND 9 is included in the file CHANGES, with the most recent +changes listed first. Change notes include tags indicating the category of +the change that was made; these categories are: + +|Category |Description | +|-------------- |-----------------------------------------------| +| [func] | New feature | +| [bug] | General bug fix | +| [security] | Fix for a significant security flaw | +| [experimental] | Used for new features when the syntax or other aspects of the design are still in flux and may change | +| [port] | Portability enhancement | +| [maint] | Updates to built-in data such as root server addresses and keys | +| [tuning] | Changes to built-in configuration defaults and constants to improve performance | +| [performance] | Other changes to improve server performance | +| [protocol] | Updates to the DNS protocol such as new RR types | +| [test] | Changes to the automatic tests, not affecting server functionality | +| [cleanup] | Minor corrections and refactoring | +| [doc] | Documentation | +| [contrib] | Changes to the contributed tools and libraries in the 'contrib' subdirectory | +| [placeholder] | Used in the main development branch to reserve change numbers for use in other branches, e.g., when fixing a bug that only exists in older releases | + +In general, [func] and [experimental] tags will only appear in new-feature +releases (i.e., those with version numbers ending in zero). Some new +functionality may be backported to older releases on a case-by-case basis. +All other change types may be applied to all currently-supported releases. + +#### Bug report identifiers + +Most notes in the CHANGES file include a reference to a bug report or +issue number. Prior to 2018, these were usually of the form `[RT #NNN]` +and referred to entries in the "bind9-bugs" RT database, which was not open +to the public. More recent entries use the form `[GL #NNN]` or, less often, +`[GL !NNN]`, which, respectively, refer to issues or merge requests in the +GitLab database. Most of these are publicly readable, unless they include +information which is confidential or security sensitive. + +To look up a GitLab issue by its number, use the URL +[https://gitlab.isc.org/isc-projects/bind9/issues/NNN](https://gitlab.isc.org/isc-projects/bind9/issues). +To look up a merge request, use +[https://gitlab.isc.org/isc-projects/bind9/merge_requests/NNN](https://gitlab.isc.org/isc-projects/bind9/merge_requests). + +In rare cases, an issue or merge request number may be followed with the +letter "P". This indicates that the information is in the private ISC +GitLab instance, which is not visible to the public. + +### <a name="ack"/> Acknowledgments + +* The original development of BIND 9 was underwritten by the + following organizations: + + Sun Microsystems, Inc. + Hewlett Packard + Compaq Computer Corporation + IBM + Process Software Corporation + Silicon Graphics, Inc. + Network Associates, Inc. + U.S. Defense Information Systems Agency + USENIX Association + Stichting NLnet - NLnet Foundation + Nominum, Inc. + +* This product includes software developed by the OpenSSL Project for use + in the OpenSSL Toolkit. + [http://www.OpenSSL.org/](http://www.OpenSSL.org/) +* This product includes cryptographic software written by Eric Young + (eay@cryptsoft.com) +* This product includes software written by Tim Hudson (tjh@cryptsoft.com) |
