BIND 9	BIND version 9 is a major rewrite of nearly all aspects of the	underlying BIND architecture. Some of the important features of	BIND 9 are:	- DNS Security	DNSSEC (signed zones)	TSIG (signed DNS requests)	- IP version 6	Answers DNS queries on IPv6 sockets	IPv6 resource records (A6, DNAME, etc.)	Bitstring Labels	Experimental IPv6 Resolver Library	- DNS Protocol Enhancements	IXFR, DDNS, Notify, EDNS0	Improved standards conformance	- Views	One server process can provide multiple "views" of	the DNS namespace, e.g. an "inside" view to certain	clients, and an "outside" view to others.	- Multiprocessor Support	- Improved Portability Architecture	BIND version 9 development has been 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 BIND 9.0.1	BIND 9.0.1 is a maintenance release, containing fixes for a	number of bugs in BIND 9.0.0 but no new features (with the	exception of a few minor features added to dig, host, and	nslookup).	Like BIND 9.0.0, BIND 9.0.1 is primarily a name server software	distribution. In addition to the name server, it 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 still considered	experimental and is not a complete replacement for the BIND 8	resolver library. In particular, applications that use the	BIND 8 res_* functions to perform DNS queries or dynamic	updates still need to be linked against the BIND 8 libraries.	BIND 9.0.1 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 wildcard	records in secure zones.	When acting as a caching server, BIND 9.0.1 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:	The option "query-source * port 53;" will not work as	expected. Instead of the wildcard address "*", you need	to use an explicit source IP address.	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.	There are known problems with thread signal handling	under Solaris 2.6.	The "isc_timer_reset" test sometimes fails on HP-UX 11	for unknown reasons, but the server itself seems to	run fine.	On FreeBSD systems, the server logs error messages	like "fcntl(8, F_SETFL, 4): Inappropriate ioctl for	device". This is due to a bug in the FreeBSD	/dev/random device. The bug has been reported	to the FreeBSD maintainers. Versions of OpenBSD	prior to 2.8 have a similar problem.	The configure option --disable-ipv6 is not functional.	--with-libtool does not work on AIX.	Due to bugs in the dnssafe library, RSA keys longer	than 2000 bits are not supported. Building	BIND 9 currently requires a UNIX system with an ANSI C compiler,	basic POSIX support, and a good pthreads implementation.	We've had successful builds and tests on the following systems:	AIX 4.3	COMPAQ Tru64 UNIX 4.0D	COMPAQ Tru64 UNIX 5 (with IPv6 EAK)	FreeBSD 3.4-STABLE	HP-UX 11	IRIX64 6.5	NetBSD-current (with unproven-pthreads-0.17)	Red Hat Linux 6.0, 6.1, 6.2	Solaris 2.6, 7, 8	Additionally, we have unverified reports of success from users	of the following systems:	Slackware Linux 7.0 with 2.4.0-test6 kernel and glibc 2.1.3	Slackware Linux 7.0.1 with glibc 2.1.3	OpenBSD 2.6, 2.8, -current	To build, just	./configure	make	Several environment variables that can be set before running	configure will affect compilation: CC	The C compiler to use.	configure tries to figure	out the right one for supported systems. CFLAGS	C compiler flags. Defaults to include -g and/or -O2	as supported by the compiler. STD_CINCLUDES	System header file directories. Can be used to specify	where add-on thread or IPv6 support is, for example.	Defaults to empty string. STD_CDEFINES	Any additional preprocessor symbols you want defined.	Defaults to empty string.	To build shared libraries, specify "--with-libtool" on the	configure command line.	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.	To see additional configure options, run "configure --help".	"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".	If you're planning on making changes to the BIND 9 source, you	should also "make depend". If you're using Emacs, you might find	"make tags" helpful.	Building with gcc is not supported, unless gcc is the vendor's usual	compiler (e.g. the various BSD systems, Linux).	Parts of the library can be tested by running "make test" from the	bin/tests subdirectory. Documentation	The BIND 9 Administrator Reference Manual is included with the	source distribution in DocBook XML and HTML format, in the	doc/arm directory.	Some of the programs in the BIND 9 distribution have man pages	under the doc/man directory. In particular, the command line	options of "named" are documented in doc/man/bind/named.8.	The man pages are currently not installed automatically by	"make install".	If you are upgrading from BIND 8, please read the migration	notes in doc/misc/migration. Bug Reports and Mailing Lists	Bugs reports should be sent to	bind9-bugs@isc.org	To join the BIND 9 Users mailing list, send mail to	bind9-users-request@isc.org	If you're planning on making changes to the BIND 9 source	code, you might want to join the BIND 9 Workers mailing list.
