BIND 9.0.0rc6 is now available. This is a release candidate for BIND 9.0.0,
fixing a number of bugs found in rc5.

        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

                Hewlett Packard
                Compaq Computer Corporation
                Process Software Corporation
                Silicon Graphics, Inc.

BIND 9.0.0rc6

        BIND 9.0.0rc6 is a release candidate for the upcoming
        9.0.0 release. The only changes expected between
        rc5 and the final release are bug fixes and documentation

        The 9.0.0 release, and this release candidate, is aimed at
        early adopters and those who wish to make use of new 9.0
        features, such as IPv6 and DNSSEC secure resolution support.

        We are running BIND 9 in production, and it has been used
        as a root name server.

        BIND 9.0.0 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 9.0.0 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 9.0.0 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.

        A number of bugs found in rc5 have been fixed. For a
        detailed list of user-visible changes, see the CHANGES file.

        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. A similar problem is
                reported to exist on OpenBSD.


        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

        To build, just


        Several environment variables that can be set before running
        configure will affect compilation:

                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 supported by the compiler.

                System header file directories. Can be used to specify
                where add-on thread or IPv6 support is, for example.
                Defaults to empty string.

                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.


        The BIND 9 Administrator Reference Manual is included with the
        source distribution in HTML and plain text format, in the
        doc/arm directory. A PDF version can be downloaded separately
        at <http://www.nominum.com/resources/>.

        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.
