Summary of functional enhancements from prior major releases of BIND 9:
BIND 9.8.0
BIND 9.8.0 includes a number of changes from BIND 9.7 and earlier
releases. New features include:
- Built-in trust anchor for the root zone, which can be
switched on via "dnssec-validation auto;"
- Support for DNS64.
- Support for response policy zones (RPZ).
- Support for writable DLZ zones.
- Improved ease of configuration of GSS/TSIG for
interoperability with Active Directory
- Support for GOST signing algorithm for DNSSEC.
- Removed RTT Banding from server selection algorithm.
- New "static-stub" zone type.
- Allow configuration of resolver timeouts via
"resolver-query-timeout" option.
- The DLZ "dlopen" driver is now built by default.
- Added a new include file with function typedefs
for the DLZ "dlopen" driver.
- Made "--with-gssapi" default.
- More verbose error reporting from DLZ LDAP.
BIND 9.7.0
BIND 9.7.0 includes a number of changes from BIND 9.6 and earlier
releases. Most are intended to simplify DNSSEC configuration.
New features include:
- Fully automatic signing of zones by "named".
- Simplified configuration of DNSSEC Lookaside Validation (DLV).
- Simplified configuration of Dynamic DNS, using the "ddns-confgen"
command line tool or the "local" update-policy option. (As a side
effect, this also makes it easier to configure automatic zone
re-signing.)
- New named option "attach-cache" that allows multiple views to
share a single cache.
- DNS rebinding attack prevention.
- New default values for dnssec-keygen parameters.
- Support for RFC 5011 automated trust anchor maintenance
- Smart signing: simplified tools for zone signing and key
maintenance.
- The "statistics-channels" option is now available on Windows.
- A new DNSSEC-aware libdns API for use by non-BIND9 applications
- On some platforms, named and other binaries can now print out
a stack backtrace on assertion failure, to aid in debugging.
- A "tools only" installation mode on Windows, which only installs
dig, host, nslookup and nsupdate.
- Improved PKCS#11 support, including Keyper support and explicit
OpenSSL engine selection.
BIND 9.6.0
Full NSEC3 support
Automatic zone re-signing
New update-policy methods tcp-self and 6to4-self
The BIND 8 resolver library, libbind, has been removed from the
BIND 9 distribution and is now available as a separate download.
Change the default pid file location from /var/run to
/var/run/{named,lwresd} for improved chroot/setuid support.
BIND 9.5.0
GSS-TSIG support (RFC 3645).
DHCID support.
Experimental http server and statistics support for named via xml.
More detailed statistics counters including those supported in BIND 8.
Faster ACL processing.
Use Doxygen to generate internal documentation.
Efficient LRU cache-cleaning mechanism.
NSID support.
BIND 9.4.0
Implemented "additional section caching (or acache)", an
internal cache framework for additional section content to
improve response performance. Several configuration options
were provided to control the behavior.
New notify type 'master-only'. Enable notify for master
zones only.
Accept 'notify-source' style syntax for query-source.
rndc now allows addresses to be set in the server clauses.
New option "allow-query-cache". This lets "allow-query"
be used to specify the default zone access level rather
than having to have every zone override the global value.
"allow-query-cache" can be set at both the options and view
levels. If "allow-query-cache" is not set then "allow-recursion"
is used if set, otherwise "allow-query" is used if set
unless "recursion no;" is set in which case "none;" is used,
otherwise the default (localhost; localnets;) is used.
rndc: the source address can now be specified.
ixfr-from-differences now takes master and slave in addition
to yes and no at the options and view levels.
Allow the journal's name to be changed via named.conf.
'rndc notify zone [class [view]]' resend the NOTIFY messages
for the specified zone.
'dig +trace' now randomly selects the next servers to try.
Report if there is a bad delegation.
Improve check-names error messages.
Make public the function to read a key file, dst_key_read_public().
dig now returns the byte count for axfr/ixfr.
allow-update is now settable at the options / view level.
named-checkconf now checks the logging configuration.
host now can turn on memory debugging flags with '-m'.
Don't send notify messages to self.
Perform sanity checks on NS records which refer to 'in zone' names.
New zone option "notify-delay". Specify a minimum delay
between sets of NOTIFY messages.
Extend adjusting TTL warning messages.
Named and named-checkzone can now both check for non-terminal
wildcard records.
"rndc freeze/thaw" now freezes/thaws all zones.
named-checkconf now check acls to verify that they only
refer to existing acls.
The server syntax has been extended to support a range of
servers.
Report differences between hints and real NS rrset and
associated address records.
Preserve the case of domain names in rdata during zone
transfers.
Restructured the data locking framework using architecture
dependent atomic operations (when available), improving
response performance on multi-processor machines significantly.
x86, x86_64, alpha, powerpc, and mips are currently supported.
UNIX domain controls are now supported.
Add support for additional zone file formats for improving
loading performance. The masterfile-format option in
named.conf can be used to specify a non-default format. A
separate command named-compilezone was provided to generate
zone files in the new format. Additionally, the -I and -O
options for dnssec-signzone specify the input and output
formats.
dnssec-signzone can now randomize signature end times
(dnssec-signzone -j jitter).
Add support for CH A record.
Add additional zone data constancy checks. named-checkzone
has extended checking of NS, MX and SRV record and the hosts
they reference. named has extended post zone load checks.
New zone options: check-mx and integrity-check.
edns-udp-size can now be overridden on a per server basis.
dig can now specify the EDNS version when making a query.
Added framework for handling multiple EDNS versions.
Additional memory debugging support to track size and mctx
arguments.
Detect duplicates of UDP queries we are recursing on and
drop them. New stats category "duplicates".
"USE INTERNAL MALLOC" is now runtime selectable.
The lame cache is now done on a <qname,qclass,qtype> basis
as some servers only appear to be lame for certain query
types.
Limit the number of recursive clients that can be waiting
for a single query (<qname,qtype,qclass>) to resolve. New
options clients-per-query and max-clients-per-query.
dig: report the number of extra bytes still left in the
packet after processing all the records.
Support for IPSECKEY rdata type.
Raise the UDP recieve buffer size to 32k if it is less than 32k.
x86 and x86_64 now have seperate atomic locking implementations.
named-checkconf now validates update-policy entries.
Attempt to make the amount of work performed in a iteration
self tuning. The covers nodes clean from the cache per
iteration, nodes written to disk when rewriting a master
file and nodes destroyed per iteration when destroying a
zone or a cache.
ISC string copy API.
Automatic empty zone creation for D.F.IP6.ARPA and friends.
Note: RFC 1918 zones are not yet covered by this but are
likely to be in a future release.
New options: empty-server, empty-contact, empty-zones-enable
and disable-empty-zone.
dig now has a '-q queryname' and '+showsearch' options.
host/nslookup now continue (default)/fail on SERVFAIL.
dig now warns if 'RA' is not set in the answer when 'RD'
was set in the query. host/nslookup skip servers that fail
to set 'RA' when 'RD' is set unless a server is explicitly
set.
Integrate contibuted DLZ code into named.
Integrate contibuted IDN code from JPNIC.
libbind: corresponds to that from BIND 8.4.7.
BIND 9.3.0
DNSSEC is now DS based (RFC 3658).
See also RFC 3845, doc/draft/draft-ietf-dnsext-dnssec-*.
DNSSEC lookaside validation.
check-names is now implemented.
rrset-order in more complete.
IPv4/IPv6 transition support, dual-stack-servers.
IXFR deltas can now be generated when loading master files,
ixfr-from-differences.
It is now possible to specify the size of a journal, max-journal-size.
It is now possible to define a named set of master servers to be
used in masters clause, masters.
The advertised EDNS UDP size can now be set, edns-udp-size.
allow-v6-synthesis has been obsoleted.
NOTE:
* Zones containing MD and MF will now be rejected.
* dig, nslookup name. now report "Not Implemented" as
NOTIMP rather than NOTIMPL. This will have impact on scripts
that are looking for NOTIMPL.
libbind: corresponds to that from BIND 8.4.5.
BIND 9.2.0
The size of the cache can now be limited using the
"max-cache-size" option.
The server can now automatically convert RFC1886-style recursive
lookup requests into RFC2874-style lookups, when enabled using the
new option "allow-v6-synthesis". This allows stub resolvers that
support AAAA records but not A6 record chains or binary labels to
perform lookups in domains that make use of these IPv6 DNS
features.
Performance has been improved.
The man pages now use the more portable "man" macros rather than
the "mandoc" macros, and are installed by "make install".
The named.conf parser has been completely rewritten. It now
supports "include" directives in more places such as inside "view"
statements, and it no longer has any reserved words.
The "rndc status" command is now implemented.
rndc can now be configured automatically.
A BIND 8 compatible stub resolver library is now included in
lib/bind.
OpenSSL has been removed from the distribution. This means that to
use DNSSEC, OpenSSL must be installed and the --with-openssl option
must be supplied to configure. This does not apply to the use of
TSIG, which does not require OpenSSL.
The source distribution now builds on Windows. See
win32utils/readme1.txt and win32utils/win32-build.txt for details.
This distribution also includes a new lightweight stub
resolver library and associated resolver daemon that fully
support forward and reverse lookups of both IPv4 and IPv6
addresses. This library is considered experimental and
is not a complete replacement for the BIND 8 resolver library.
Applications that use the BIND 8 res_* functions to perform
DNS lookups or dynamic updates still need to be linked against
the BIND 8 libraries. For DNS lookups, they can also use the
new "getrrsetbyname()" API.
BIND 9.2 is capable of acting as an authoritative server
for DNSSEC secured zones. This functionality is believed to
be stable and complete except for lacking support for
verifications involving wildcard records in secure zones.
When acting as a caching server, BIND 9.2 can be configured
to perform DNSSEC secure resolution on behalf of its clients.
This part of the DNSSEC implementation is still considered
experimental. For detailed information about the state of the
DNSSEC implementation, see the file doc/misc/dnssec.
There are a few known bugs:
On some systems, IPv6 and IPv4 sockets interact in
unexpected ways. For details, see doc/misc/ipv6.
To reduce the impact of these problems, the server
no longer listens for requests on IPv6 addresses
by default. If you need to accept DNS queries over
IPv6, you must specify "listen-on-v6 { any; };"
in the named.conf options statement.
FreeBSD prior to 4.2 (and 4.2 if running as non-root)
and OpenBSD prior to 2.8 log messages like
"fcntl(8, F_SETFL, 4): Inappropriate ioctl for device".
This is due to a bug in "/dev/random" and impacts the
server's DNSSEC support.
OS X 10.1.4 (Darwin 5.4), OS X 10.1.5 (Darwin 5.5) and
OS X 10.2 (Darwin 6.0) reports errors like
"fcntl(3, F_SETFL, 4): Operation not supported by device".
This is due to a bug in "/dev/random" and impacts the
server's DNSSEC support.
--with-libtool does not work on AIX.
A bug in some versions of the Microsoft DNS server can cause zone
transfers from a BIND 9 server to a W2K server to fail. For details,
see the "Zone Transfers" section in doc/misc/migration.

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 is 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.

BIND 9.9 features
BIND 9.9.0 includes a number of changes from BIND 9.8 and earlier
releases. New features include:
* Inline signing, allowing automatic DNSSEC signing of master zones
without modification of the zonefile, or "bump in the wire" signing in
slaves.
* NXDOMAIN redirection.
* New rndc flushtree command clears all data under a given name from the
DNS cache.
* New rndc sync command dumps pending changes in a dynamic zone to disk
without a freeze/thaw cycle.
* New rndc signing command displays or clears signing status records in
auto-dnssec zones.
* NSEC3 parameters for auto-dnssec zones can now be set prior to
signing, eliminating the need to initially sign with NSEC.
* Startup time improvements on large authoritative servers.
* Slave zones are now saved in raw format by default.
* Several improvements to response policy zones (RPZ).
* Improved hardware scalability by using multiple threads to listen for
queries and using finer-grained client locking
* The also-notify option now takes the same syntax as masters, so it can
used named masterlists and TSIG keys.
* dnssec-signzone -D writes an output file containing only DNSSEC data,
which can be included by the primary zone file.
* dnssec-signzone -R forces removal of signatures that are not expired
but were created by a key which no longer exists.
* dnssec-signzone -X allows a separate expiration date to be specified
for DNSKEY signatures from other signatures.
* New -L option to dnssec-keygen, dnssec-settime, and
dnssec-keyfromlabel sets the default TTL for the key.
* dnssec-dsfromkey now supports reading from standard input, to make it
easier to convert DNSKEY to DS.
* RFC 1918 reverse zones have been added to the empty-zones table per
RFC
6303.
* Dynamic updates can now optionally set the zone's SOA serial number to
the current UNIX time.
* DLZ modules can now retrieve the source IP address of the querying
client.
* request-ixfr option can now be set at the per-zone level.
* dig +rrcomments turns on comments about DNSKEY records, indicating
their key ID, algorithm and function
* Simplified nsupdate syntax and added readline support
BIND 9.9.1
BIND 9.9.1 is a maintenance release.
BIND 9.9.2
BIND 9.9.2 is a maintenance release, and addresses the security flaw
described in CVE-2012-4244.
BIND 9.9.3
BIND 9.9.3 is a maintenance release and addresses the security flaws
described in CVE-2012-5688, CVE-2012-5689 and CVE-2013-2266.
BIND 9.9.4
BIND 9.9.4 is a maintenance release, and addresses the security flaws
described in CVE-2013-3919 and CVE-2013-4854. It also introduces DNS
Response Rate Limiting (DNS RRL) as a compile-time option. To use this
feature, configure with the --enable-rrl option.
BIND 9.9.5
BIND 9.9.5 is a maintenance release, and addresses the security flaws
described in CVE-2013-6320 and CVE-2014-0591. It also includes the
following functional enhancements:
* named now preserves the capitalization of names when responding to
queries.
* new dnssec-importkey command allows the use of offline DNSSEC keys
with automatic DNSKEY management.
* When re-signing a zone, the new dnssec-signzone -Q option drops
signatures from keys that are still published but are no longer
active.
* named-checkconf -px will print the contents of configuration files
with the shared secrets obscured, making it easier to share
configuration (e.g. when submitting a bug report) without revealing
private information.
BIND 9.9.6
BIND 9.9.6 is a maintenance release, and also includes the following new
functionality.
* The former behavior with respect to capitalization of names (prior to
BIND 9.9.5) can be restored for specific clients via the new
no-case-compress ACL.
BIND 9.9.7
BIND 9.9.7 is a maintenance release, and addresses the security flaws
described in CVE-2014-8500 and CVE-2015-1349.
BIND 9.9.8
BIND 9.9.8 is a maintenance release, and addresses the security flaws
described in CVE-2015-4620, CVE-2015-5477, CVE-2015-5722, and
CVE-2015-5986.
It also makes the following new features available via a compile-time
option:
* New "fetchlimit" quotas are now available for the use of recursive
resolvers that are are under high query load for domains whose
authoritative servers are nonresponsive or are experiencing a denial
of service attack.
+ fetches-per-server limits the number of simultaneous queries that
can be sent to any single authoritative server. The configured
value is a starting point; it is automatically adjusted downward
if the server is partially or completely non-responsive. The
algorithm used to adjust the quota can be configured via the
fetch-quota-params option.
+ fetches-per-zone limits the number of simultaneous queries that
can be sent for names within a single domain. (Note: Unlike
fetches-per-server, this value is not self-tuning.)
+ New stats counters have been added to count queries spilled due to
these quotas. NOTE: These options are NOT built in by default; use
configure --enable-fetchlimit to enable them.
BIND 9.9.9
BIND 9.9.9 is a maintenance release and addresses bugs found in BIND 9.9.8
and earlier, as well as the security flaws described in CVE-2015-8000,
CVE-2015-8461, CVE-2015-8704, CVE-2016-1285, CVE-2016-1286, CVE-2016-2775

CVE-2017-3137, and CVE-2017-3138.
Building BIND
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 is also available for Windows XP, 2003, 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
(NOTE: Using multiple processors in make is not reliable and is not
advised.)
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
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
libxml2 http://xmlsoft.org If this is installed at a nonstandard location,
specify the prefix using --with-libxml2=/prefix.
Python requires the 'argparse' module to be available. 'argparse' is a
standard module as of Python 2.7 and Python 3.2.
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 by running the script 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

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
Used in the master development branch to reserve change
[placeholder] 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.
