b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt BIND 9.10.0 includes a number of changes from BIND 9.9 and earlier
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt releases. New features include:
9d1f3953d3226a9e85d26bc59e62b29c16d14e77Evan Hunt - DNS Response-rate limiting (DNS RRL), which blunts the
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt impact of reflection and amplification attacks, is always
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt compiled in and no longer requires a compile-time option
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt to enable it.
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt - An experimental "Source Identity Token" (SIT) EDNS option
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt is now available. Similar to DNS Cookies as invented by
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt Donald Eastlake 3rd, these are designed to enable clients
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt to detect off-path spoofed responses, and to enable servers
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt to detect spoofed-source queries. Servers can be configured
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt to send smaller responses to clients that have not identified
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt themselves using a SIT option, reducing the effectiveness of
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt amplification attacks. RRL processing has also been updated;
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt clients proven to be legitimate via SIT are not subject to
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt rate limiting. Use "configure --enable-sit" to enable this
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt feature in BIND.
83d59691e3d25938474ea1e0b8a0385e1a77da40Evan Hunt - A new zone file format, "map", stores zone data in a
83d59691e3d25938474ea1e0b8a0385e1a77da40Evan Hunt format that can be mapped directly into memory, allowing
83d59691e3d25938474ea1e0b8a0385e1a77da40Evan Hunt significantly faster zone loading.
83d59691e3d25938474ea1e0b8a0385e1a77da40Evan Hunt - "delve" (domain entity lookup and validation engine) is a
83d59691e3d25938474ea1e0b8a0385e1a77da40Evan Hunt new tool with dig-like semantics for looking up DNS data
83d59691e3d25938474ea1e0b8a0385e1a77da40Evan Hunt and performing internal DNSSEC validation. This allows
83d59691e3d25938474ea1e0b8a0385e1a77da40Evan Hunt easy validation in environments where the resolver may
83d59691e3d25938474ea1e0b8a0385e1a77da40Evan Hunt not be trustworthy, and assists with troubleshooting of
83d59691e3d25938474ea1e0b8a0385e1a77da40Evan Hunt DNSSEC problems.
45e74d65bd981a97c5da2f86e8557c9843a0c7c0Evan Hunt - Improved EDNS(0) processing for better resolver performance
45e74d65bd981a97c5da2f86e8557c9843a0c7c0Evan Hunt and reliability over slow or lossy connections.
6a3fa181d1253db5191139e20231512eebaddeebEvan Hunt - A new "configure --with-tuning=large" option tunes certain
6a3fa181d1253db5191139e20231512eebaddeebEvan Hunt compiled-in constants and default settings to values better
6a3fa181d1253db5191139e20231512eebaddeebEvan Hunt suited to large servers with abundant memory. This can
6a3fa181d1253db5191139e20231512eebaddeebEvan Hunt improve performance on such servers, but will consume more
6a3fa181d1253db5191139e20231512eebaddeebEvan Hunt memory and may degrade performance on smaller systems.
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt - Substantial improvement in response-policy zone (RPZ)
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt performance. Up to 32 response-policy zones can be
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt configured with minimal performance loss.
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt - To improve recursive resolver performance, cache records
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt which are still being requested by clients can now be
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt automatically refreshed from the authoritative server
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt before they expire, reducing or eliminating the time
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt window in which no answer is available in the cache.
9d1f3953d3226a9e85d26bc59e62b29c16d14e77Evan Hunt - New "rpz-client-ip" triggers and drop policies allowing
9d1f3953d3226a9e85d26bc59e62b29c16d14e77Evan Hunt response policies based on the IP address of the client.
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt - ACLs can now be specified based on geographic location
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt using the MaxMind GeoIP databases. Use "configure
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt --with-geoip" to enable.
45e74d65bd981a97c5da2f86e8557c9843a0c7c0Evan Hunt - Zone data can now be shared between views, allowing
45e74d65bd981a97c5da2f86e8557c9843a0c7c0Evan Hunt multiple views to serve the same zones authoritatively
daa098822e9798fa22fa704cfb1dddf96c8f253bJeremy C. Reed without storing multiple copies in memory.
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt - New XML schema (version 3) for the statistics channel
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt includes many new statistics and uses a flattened XML tree
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt for faster parsing. The older schema is now deprecated.
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt - A new stylesheet, based on the Google Charts API, displays
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt XML statistics in charts and graphs on javascript-enabled
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt - The statistics channel can now provide data in JSON
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt format as well as XML.
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt - New stats counters track TCP and UDP queries on a
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt per-zone basis.
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt - The internal and export versions of the BIND libraries
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt (libisc, libdns, etc) have been unified so that external
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt library clients can use the same libraries as BIND itself.
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt - A new compile-time option, "configure --enable-native-pkcs11",
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt allows BIND 9 cryptography functions to use the PKCS#11 API
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt natively, so that BIND can drive a cryptographic hardware
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt service module (HSM) directly instead of using a modified
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt OpenSSL as an intermediary. This has been tested with the
db955e6f01e7a40c7c69b21495e316a9f29102a8Evan Hunt Thales nShield HSM and with SoftHSMv2 from the Open DNSSEC
35f6a21f5f8114542c050bfcb484b39ce513d4bdEvan Hunt - The new "max-zone-ttl" option enforces maximum TTLs for
35f6a21f5f8114542c050bfcb484b39ce513d4bdEvan Hunt zones. This can simplify the process of rolling DNSSEC keys
35f6a21f5f8114542c050bfcb484b39ce513d4bdEvan Hunt by guaranteeing that cached signatures will have expired
35f6a21f5f8114542c050bfcb484b39ce513d4bdEvan Hunt within the specified amount of time.
83d59691e3d25938474ea1e0b8a0385e1a77da40Evan Hunt - New "dnssec-coverage" tool to check DNSSEC key coverage
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt for a zone and report if a lapse in signing coverage has
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt been inadvertently scheduled.
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt - Signing algorithm flexibility and other improvements
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt for the "rndc" control channel.
83d59691e3d25938474ea1e0b8a0385e1a77da40Evan Hunt - "named-checkzone" and "named-compilezone" can now read
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt journal files, allowing them to process dynamic zones.
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt - Multiple DLZ databases can now be configured. Individual
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt zones can be configured to be served from a specific DLZ
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt database. DLZ databases now serve zones of type "master"
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt and "redirect".
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt - "rndc zonestatus" reports information about a specified zone.
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt - "named" now listens on IPv6 as well as IPv4 interfaces
dc3ac7e79aee3821d1877a41adcd6d6eec5a4395Evan Hunt - "named" now preserves the capitalization of names when
c9221313204f9720b3ae54c3ef1d89743180223aEvan Hunt responding to queries. The former behavior can be restored
6a3fa181d1253db5191139e20231512eebaddeebEvan Hunt for specific clients via the new "no-case-compress" ACL.
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt - new "dnssec-importkey" command allows the use of offline
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt DNSSEC keys with automatic DNSKEY management.
83d59691e3d25938474ea1e0b8a0385e1a77da40Evan Hunt - New "named-rrchecker" tool to verify the syntactic
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt correctness of individual resource records.
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt - When re-signing a zone, the new "dnssec-signzone -Q" option
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt drops signatures from keys that are still published but are
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt no longer active.
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt - "named-checkconf -px" will print the contents of configuration
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt files with the shared secrets obscured, making it easier to
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt share configuration (e.g. when submitting a bug report)
b751788932cf1a6d98ae83355f38a080125c2f3eEvan Hunt without revealing private information.
c9221313204f9720b3ae54c3ef1d89743180223aEvan Hunt - "rndc scan" causes named to re-scan network interfaces for
c9221313204f9720b3ae54c3ef1d89743180223aEvan Hunt changes in local addresses.
c9221313204f9720b3ae54c3ef1d89743180223aEvan Hunt - On operating systems with support for routing sockets,
c9221313204f9720b3ae54c3ef1d89743180223aEvan Hunt network interfaces are re-scanned automatically whenever
c9221313204f9720b3ae54c3ef1d89743180223aEvan Hunt they change.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt BIND 9.9.0 includes a number of changes from BIND 9.8 and earlier
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt releases. New features include:
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - Inline signing, allowing automatic DNSSEC signing of
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt master zones without modification of the zonefile, or
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt "bump in the wire" signing in slaves.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - NXDOMAIN redirection.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - New 'rndc flushtree' command clears all data under a given
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt name from the DNS cache.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - New 'rndc sync' command dumps pending changes in a dynamic
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt zone to disk without a freeze/thaw cycle.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - New 'rndc signing' command displays or clears signing status
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt records in 'auto-dnssec' zones.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - NSEC3 parameters for 'auto-dnssec' zones can now be set prior
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt to signing, eliminating the need to initially sign with NSEC.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - Startup time improvements on large authoritative servers.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - Slave zones are now saved in raw format by default.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - Several improvements to response policy zones (RPZ).
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - Improved hardware scalability by using multiple threads

3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - The 'also-notify' option now takes the same syntax as
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt 'masters', so it can used named masterlists and TSIG keys.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - 'dnssec-signzone -D' writes an output file containing only DNSSEC
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt data, which can be included by the primary zone file.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - 'dnssec-signzone -R' forces removal of signatures that are
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt not expired but were created by a key which no longer exists.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - 'dnssec-signzone -X' allows a separate expiration date to
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt be specified for DNSKEY signatures from other signatures.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - New '-L' option to dnssec-keygen, dnssec-settime, and
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt dnssec-keyfromlabel sets the default TTL for the key.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - dnssec-dsfromkey now supports reading from standard input,
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt to make it easier to convert DNSKEY to DS.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - RFC 1918 reverse zones have been added to the empty-zones
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt table per RFC 6303.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - Dynamic updates can now optionally set the zone's SOA serial

3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - DLZ modules can now retrieve the source IP address of
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt the querying client.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - 'request-ixfr' option can now be set at the per-zone level.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - 'dig +rrcomments' turns on comments about DNSKEY records,
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt indicating their key ID, algorithm and function
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt - Simplified nsupdate syntax and added readline support
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt BIND 9 currently requires a UNIX system with an ANSI C compiler,
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt basic POSIX support, and a 64 bit integer type.

3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt Several environment variables that can be set before running
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt configure will affect compilation:
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt The C compiler to use. configure tries to figure
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt out the right one for supported systems.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt C compiler flags. Defaults to include -g and/or -O2
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt as supported by the compiler. Please include '-g'
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt if you need to set CFLAGS.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt STD_CINCLUDES

3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt Defaults to empty string.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt STD_CDEFINES
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt Any additional preprocessor symbols you want defined.

3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt BUILD_CFLAGS (optional)
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt BUILD_CPPFLAGS (optional)
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt Possible Settings:

3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt On most platforms, BIND 9 is built with multithreading
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt support, allowing it to take advantage of multiple CPUs.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt You can configure this by specifying "--enable-threads" or
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt "--disable-threads" on the configure command line. The default
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt is to enable threads, except on some older operating systems
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt on which threads are known to have had problems in the past.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt (Note: Prior to BIND 9.10, the default was to disable threads on
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt Linux systems; this has been reversed. On Linux systems, the
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt threaded build is known to change BIND's behavior with respect
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt to file permissions; it may be necessary to specify a user with
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt the -u option when running named.)
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt To build shared libraries, specify "--with-libtool" on the
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt configure command line.
6a3fa181d1253db5191139e20231512eebaddeebEvan Hunt Certain compiled-in constants and default settings can be
6a3fa181d1253db5191139e20231512eebaddeebEvan Hunt increased to values better suited to large servers with abundant
6a3fa181d1253db5191139e20231512eebaddeebEvan Hunt memory resources (e.g, 64-bit servers with 12G or more of memory)
6a3fa181d1253db5191139e20231512eebaddeebEvan Hunt by specifying "--with-tuning=large" on the configure command
6a3fa181d1253db5191139e20231512eebaddeebEvan Hunt line. This can improve performance on big servers, but will
6a3fa181d1253db5191139e20231512eebaddeebEvan Hunt consume more memory and may degrade performance on smaller
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt For the server to support DNSSEC, you need to build it
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt with crypto support. You must have OpenSSL 0.9.5a
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt or newer installed and specify "--with-openssl" on the
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt configure command line. If OpenSSL is installed under
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt a nonstandard prefix, you can tell configure where to
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt look for it using "--with-openssl=/prefix".
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt To support the HTTP statistics channel, the server must
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt be linked with at least one of the following: libxml2
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt (http://xmlsoft.org) or json-c (https://github.com/json-c).
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt If these are installed at a nonstandard prefix, use
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt "--with-libxml2=/prefix" or "--with-libjson=/prefix".
daa098822e9798fa22fa704cfb1dddf96c8f253bJeremy C. Reed On some platforms it is necessary to explicitly request large
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt file support to handle files bigger than 2GB. This can be
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt done by "--enable-largefile" on the configure command line.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt Support for the "fixed" rrset-order option can be enabled
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt or disabled by specifying "--enable-fixed-rrset" or
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt "--disable-fixed-rrset" on the configure command line.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt The default is "disabled", to reduce memory footprint.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt If your operating system has integrated support for IPv6, it
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt will be used automatically. If you have installed KAME IPv6
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt separately, use "--with-kame[=PATH]" to specify its location.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt "make install" will install "named" and the various BIND 9 libraries.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt By default, installation is into /usr/local, but this can be changed
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt with the "--prefix" option when running "configure".
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt You may specify the option "--sysconfdir" to set the directory
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt where configuration files like "named.conf" go by default,
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt and "--localstatedir" to set the default parent directory
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt of "run/named.pid". For backwards compatibility with BIND 8,
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt --sysconfdir defaults to "/etc" and --localstatedir defaults to
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt "/var" if no --prefix option is given. If there is a --prefix
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt option, sysconfdir defaults to "$prefix/etc" and localstatedir
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt defaults to "$prefix/var".
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt To see additional configure options, run "configure --help".
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt Note that the help message does not reflect the BIND 8
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt compatibility defaults for sysconfdir and localstatedir.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt If you're planning on making changes to the BIND 9 source, you
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt should also "make depend". If you're using Emacs, you might find
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt "make tags" helpful.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt If you need to re-run configure please run "make distclean" first.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt This will ensure that all the option changes take.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt Building with gcc is not supported, unless gcc is the vendor's usual
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt compiler (e.g. the various BSD systems, Linux).
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt Known compiler issues:
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt * gcc-3.2.1 and gcc-3.1.1 is known to cause problems with solaris-x86.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt * gcc prior to gcc-3.2.3 ultrasparc generates incorrect code at -02.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt * gcc-3.3.5 powerpc generates incorrect code at -02.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt * Irix, MipsPRO 7.4.1m is known to cause problems.
3b1b34f762cf4a9a4e09d3ef03becc0d08acddb9Evan Hunt A limited test suite can be run with "make test". Many of
