Introduction
Thank you for using BIND!
BIND is open source software that implements the Domain Name System (DNS)
protocols for the Internet. It is a reference implementation of those
protocols, but it is also production-grade software, suitable for use in
high-volume and high-reliability applications. It is by far the most
widely used DNS software, providing a robust and stable platform on top of
which organizations can build distributed computing systems with the
knowledge that those systems are fully compliant with published DNS
standards.
BIND is and will always remain free and openly available. It can be used
and modified in any way by anyone.
BIND is maintained by the Internet Systems Consortium, a public-benefit
501(c)(3) nonprofit, using a "managed open source" approach: anyone can
see the source, but only ISC employees have commit access. Until recently,
the source could only be seen once ISC had published a release: read
access to the source repository was restricted just as commit access was.
That's now changing, with the opening of a public git mirror to the BIND
source tree (see below).
Access to source code
Public BIND releases are always available from the ISC FTP site.
A public-access GIT repository is also available at https://gitlab.isc.org
. This repository is a mirror, updated several times per day, of the
source repository maintained by ISC. It contains all the public release
branches; upcoming releases can be viewed in their current state at any
time. It does not contain development branches or unreviewed work in
progress. Commits which address security vulnerablilities are withheld
until after public disclosure.
You can browse the source online via https://gitlab.isc.org/isc-projects/
bind9
To clone the repository, use:
$ git clone https://gitlab.isc.org/isc-projects/bind9.git
Release branch names are of the form v9_X, where X represents the second
number in the BIND 9 version number. So, to check out the BIND 9.12
branch, use:
$ git checkout v9_12
Whenever a branch is ready for publication, a tag will be placed of the
form v9_X_Y. The 9.12.0 release, for instance, is tagged as v9_12_0.
The branch in which the next major release is being developed is called
master.
Reporting bugs
Reports of flaws in the BIND package, including software bugs, errors in
the documentation, missing files in the tarball, suggested changes or
requests for new features, etc, can be filed using https://gitlab.isc.org/
isc-projects/bind9/issues.
Due to a large ticket backlog, we are sometimes slow to respond,
especially if a bug is cosmetic or if a feature request is vague or low in
priority, but we will try at least to acknowledge legitimate bug reports
within a week.
ISC's ticketing system is publicly readable; however, you must have an
account to file a new issue. You can either register locally or use
credentials from an existing account at GitHub, GitLab, Google, Twitter,
or Facebook.
Reporting possible security issues
If you think you may be seeing a potential security vulnerability in BIND
(for example, a crash with REQUIRE, INSIST, or ASSERT failure), please
report it immediately by emailing to security-officer@isc.org. Plain-text
e-mail is not a secure choice for communications concerning undisclosed
security issues so please encrypt your communications to us if possible,
using the ISC Security Officer public key.
Do not discuss undisclosed security vulnerabilites on any public mailing
list. ISC has a long history of handling reported vulnerabilities promptly
and effectively and we respect and acknowledge responsible reporters.
ISC's Security Vulnerability Disclosure Policy is documented at https://
kb.isc.org/article/AA-00861/0.
If you have a crash, you may want to consult ?What to do if your BIND or
DHCP server has crashed.?
Contributing code
BIND is licensed under the Mozilla Public License 2.0. Earier versions
(BIND 9.10 and earlier) were licensed under the ISC License
ISC does not require an explicit copyright assignment for patch
contributions. However, by submitting a patch to ISC, you implicitly
certify that you are the author of the code, that you intend to reliquish
exclusive copyright, and that you grant permission to publish your work
under the open source license used for the BIND version(s) to which your
patch will be applied.
BIND code
Patches for BIND may be submitted directly via merge requests in ISC's
Gitlab source repository for BIND.
Patches can also be submitted as diffs against a specific version of BIND
-- preferably the current top of the master branch. Diffs may be generated
using either git format-patch or git diff.
Those wanting to write code for BIND may be interested in the developer
information page, which includes information about BIND design and coding
practices, including discussion of internal APIs and overall system
architecture. (This is a work in progress, and still quite preliminary.)
Every patch submitted will be reviewed by ISC engineers following our code
review process before it is merged.
It may take considerable time to review patch submissions, especially if
they don't meet ISC style and quality guidelines. If a patch is a good
idea, we can and will do additional work to bring it up to par, but if
we're busy with other work, it may take us a long time to get to it.
To ensure your patch is acted on as promptly as possible, please:
* Try to adhere to the BIND 9 coding style.
* Run make check to ensure your change hasn't caused any functional
regressions.
* Document your work, both in the patch itself and in the accompanying
email.
* In patches that make non-trivial functional changes, include system
tests if possible; when introducing or substantially altering a
library API, include unit tests. See Testing for more information.
Changes to configure
If you need to make changes to configure, you should not edit it directly;
instead, edit configure.in, then run autoconf. Similarly, instead of
editing config.h.in directly, edit configure.in and run autoheader.
When submitting a patch as a diff, it's fine to omit the configure diffs
to save space. Just send the configure.in diffs and we'll generate the new
configure during the review process.
Documentation
All functional changes should be documented. There are three types of
documentation in the BIND source tree:
* Man pages are kept alongside the source code for the commands they
document, in files ending in .docbook; for example, the named man page
is bin/named/named.docbook.
* The BIND 9 Administrator Reference Manual is mostly in doc/arm/
Bv9ARM-book.xml, plus a few other XML files that are included in it.
* API documentation is in the header file describing the API, in
Doxygen-formatted comments.
It is not necessary to edit any documentation files other than these; all
PDF, HTML, and nroff-format man page files will be updated automatically
from the docbook and XML files after merging.
Patches to improve existing documentation are also very welcome!
Tests
BIND is a large and complex project. We rely heavily on continuous
automated testing and cannot merge new code without adequate test
coverage. Please see the 'Testing' section of doc/dev/dev.md for more
information.
Thanks
Thank you for your interest in contributing to the ongoing development of
BIND.
Setting the STD_CDEFINES environment variable before running configure can
be used to enable certain compile-time options that are not explicitly
defined in configure.
Some of these settings are:
Setting Description
Overwrite memory with tag values when allocating
-DISC_MEM_DEFAULTFILL=1 or freeing it; this impairs performance but
makes debugging of memory problems easier.
Don't track memory allocations by file and line
-DISC_MEM_TRACKLINES=0 number; this improves performance but makes
debugging more difficult.
-DISC_FACILITY=LOG_LOCAL0 Change the default syslog facility for named
-DNS_CLIENT_DROPPORT=0 Disable dropping queries from particular
well-known ports:
-DCHECK_SIBLING=0 Don't check sibling glue in named-checkzone
-DCHECK_LOCAL=0 Don't check out-of-zone addresses in
named-checkzone
-DNS_RUN_PID_DIR=0 Create default PID files in ${localstatedir}/run
rather than ${localstatedir}/run/named/
Disable the use of inline functions to implement
-DISC_BUFFER_USEINLINE=0 the isc_buffer API: this reduces performance but
may be useful when debugging
-DISC_HEAP_CHECK Test heap consistency after every heap
operation; used when debugging

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), 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 licenced 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.
For a detailed list of changes made throughout the history of BIND 9, see
the file CHANGES. See below for details on the CHANGES file format.
For up-to-date release notes and errata, see http://www.isc.org/software/
bind9/releasenotes
For information about supported platforms, see PLATFORMS.
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 at 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, please send mail to security-officer@isc.org.
Professional support and training for BIND are available from ISC at
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.
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.
Contributing to BIND
ISC maintains a public git repository for BIND; details can be found at
http://www.isc.org/git/.
Information for BIND contributors can be found in the following files: -
General information: CONTRIBUTING.md - BIND 9 code style: doc/dev/style.md
- BIND architecture and developer guide: doc/dev/dev.md
Patches for BIND may be submitted as Merge Requests in the ISC GitLab
server at at 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 and
including your patch as an attachment, preferably generated by git
format-patch.
BIND 9.13 features
BIND 9.13 is the newest development branch of BIND 9. It includes a number
of changes from BIND 9.12 and earlier releases. New features include:
* The default value of "dnssec-validation" is now "auto".
* Support for IDNA2008 when linking with libidn2.
* "Root key sentinel" support, enabling validating resolvers to indicate
via a special query which trust anchors are configured for the root
zone.
* Secondary zones can now be configured as "mirror" zones; their
contents are transferred in as with traditional slave zones, but are
subject to DNSSEC validation and are not treated as authoritative data
when answering. This makes it easier to configure a local copy of the
root zone as described in RFC 7706.
* QNAME minimization is now supported
* The "validate-except" option allows configuration of domains below
which DNSSEC validation should not be performed.
In addition, cryptographic support has been modernized. BIND now uses the
best available pseudo-random number generator for the platform on which
it's built. Very old versions of OpenSSL are no longer supported.
Cryptography is now mandatory; building BIND without DNSSEC is now longer
supported.
Building BIND
Minimally, BIND requires a UNIX or Linux system with an ANSI C compiler,
basic POSIX support, and a 64-bit integer type. Successful builds have
been observed on many versions of Linux and UNIX, including RedHat,
Fedora, Debian, Ubuntu, SuSE, Slackware, FreeBSD, NetBSD, OpenBSD, Mac OS
X, Solaris, HP-UX, AIX, SCO OpenServer, and OpenWRT.
BIND requires a cryptography provider library such as OpenSSL or a
hardware service module supporting PKCS#11. On Linux, BIND requires the
libcap library to set process privileges, though this requirement can be
overridden by disabling capability support at compile time. See
Compile-time options below for details on other libraries that may be
required to support optional features.
BIND is also available for Windows 2008 and higher. See win32utils/
readme1st.txt for details on building for Windows systems.
To build on a UNIX or Linux system, use:
$ ./configure
$ make
If you're planning on making changes to the BIND 9 source, you should run
make depend. If you're using Emacs, you might find make tags helpful.
Several environment variables that can be set before running configure
will affect compilation:
Variable Description
CC The C compiler to use. configure tries to figure out the
right one for supported systems.
C compiler flags. Defaults to include -g and/or -O2 as
CFLAGS supported by the compiler. Please include '-g' if you need
to set CFLAGS.
System header file directories. Can be used to specify
STD_CINCLUDES where add-on thread or IPv6 support is, for example.
Defaults to empty string.
Any additional preprocessor symbols you want defined.
STD_CDEFINES Defaults to empty string. For a list of possible settings,
see the file OPTIONS.
LDFLAGS Linker flags. Defaults to empty string.
BUILD_CC Needed when cross-compiling: the native C compiler to use
when building for the target system.
BUILD_CFLAGS Optional, used for cross-compiling
BUILD_CPPFLAGS
BUILD_LDFLAGS
BUILD_LIBS
macOS
Building on macOS assumes that the "Command Tools for Xcode" is installed.
This can be downloaded from https://developer.apple.com/download/more/ or
if you have Xcode already installed you can run "xcode-select --install".
This will add /usr/include to the system and install the compiler and
other tools so that they can be easily found.
Compile-time options
To see a full list of configuration options, run configure --help.
On most platforms, BIND 9 is built with multithreading support, allowing
it to take advantage of multiple CPUs. You can configure this by
specifying --enable-threads or --disable-threads on the configure command
line. The default is to enable threads, except on some older operating
systems on which threads are known to have had problems in the past.
(Note: Prior to BIND 9.10, the default was to disable threads on Linux
systems; this has now been reversed. On Linux systems, the threaded build
is known to change BIND's behavior with respect to file permissions; it
may be necessary to specify a user with the -u option when running named.)
To build shared libraries, specify --with-libtool on the configure command
line.
Certain compiled-in constants and default settings can be increased to
values better suited to large servers with abundant memory resources (e.g,
64-bit servers with 12G or more of memory) by specifying --with-tuning=
large on the configure command line. This can improve performance on big
servers, but will consume more memory and may degrade performance on
smaller systems.
For the server to support DNSSEC, you need to build it with crypto
support. To use OpenSSL, you should have OpenSSL 1.0.2e or newer
installed. If the OpenSSL library is installed in a nonstandard location,
specify the prefix using --with-openssl=<PREFIX> on the configure command
line. To use a PKCS#11 hardware service module for cryptographic
operations, specify the path to the PKCS#11 provider library using
--with-pkcs11=<PREFIX>, and configure BIND with --enable-native-pkcs11.
To support the HTTP statistics channel, the server must be linked with at
least one of the following: libxml2 http://xmlsoft.org or json-c https://
github.com/json-c. If these are installed at a nonstandard location,
specify the prefix using --with-libxml2=/prefix or --with-libjson=/prefix.
To support compression on the HTTP statistics channel, the server must be
linked against libzlib. If this is installed in a nonstandard location,
specify the prefix using --with-zlib=/prefix.
To support storing configuration data for runtime-added zones in an LMDB
database, the server must be linked with liblmdb. If this is installed in
a nonstandard location, specify the prefix using with-lmdb=/prefix.
To support GeoIP location-based ACLs, the server must be linked with
libGeoIP. This is not turned on by default; BIND must be configured with
--with-geoip. If the library is installed in a nonstandard location,
specify the prefix using --with-geoip=/prefix.
For DNSTAP packet logging, you must have installed libfstrm https://
github.com/farsightsec/fstrm and libprotobuf-c https://
developers.google.com/protocol-buffers, and BIND must be configured with
--enable-dnstap.
On Linux, process capabilities are managed in user space using the libcap
library, which can be installed on most Linux systems via the libcap-dev
or libcap-devel module. Process capability support can also be disabled by
configuring with --disable-linux-caps.
Portions of BIND that are written in Python, including dnssec-keymgr,
dnssec-coverage, dnssec-checkds, and some of the system tests, require the
'argparse' and 'ply' modules to be available. 'argparse' is a standard
module as of Python 2.7 and Python 3.2. 'ply' is available from https://
pypi.python.org/pypi/ply.
On some platforms it is necessary to explicitly request large file support
to handle files bigger than 2GB. This can be done by using
--enable-largefile on the configure command line.
Support for the "fixed" rrset-order option can be enabled or disabled by
specifying --enable-fixed-rrset or --disable-fixed-rrset on the configure
command line. By default, fixed rrset-order is disabled to reduce memory
footprint.
If your operating system has integrated support for IPv6, it will be used
automatically. If you have installed KAME IPv6 separately, use --with-kame
[=PATH] to specify its location.
make install will install named and the various BIND 9 libraries. By
default, installation is into /usr/local, but this can be changed with the
--prefix option when running configure.
You may specify the option --sysconfdir to set the directory where
configuration files like named.conf go by default, and --localstatedir to
set the default parent directory of run/named.pid. For backwards
compatibility with BIND 8, --sysconfdir defaults to /etc and
--localstatedir defaults to /var if no --prefix option is given. If there
is a --prefix option, sysconfdir defaults to $prefix/etc and localstatedir
defaults to $prefix/var.
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 Automated Testing Framework (ATF). To run
them, use configure --with-atf, then run make test or make unit.
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.
Additional information on various subjects can be found in other README
files throughout the source tree.
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:
