BIND 9.1.0b2
|
||||
BIND 9.2
|
||||
|
||||
BIND 9.1.0b2 is the second beta release of BIND 9.1.0.
|
||||
It fixes a number of bugs in 9.1.0b1 and adds some new
|
||||
features such as a multithreaded DNSSEC signer and
|
||||
support for "rndc dumpdb" command.
|
||||
This is a snapshot of the development source tree that
|
||||
will become BIND 9.2. Bind 9.2 will have a number of
|
||||
new features over 9.1, including:
|
||||
|
||||
Other features added since 9.0.x include:
|
||||
- The ability to automatically convert RFC1886-style
|
||||
recursive lookup requests into RFC2874-style lookups,
|
||||
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.
|
||||
|
||||
- Many BIND 8 features previously unimplemented in BIND 9,
|
||||
including domain-specific forwarding, the $GENERATE
|
||||
master file directive, and the "blackhole", "dialup",
|
||||
and "sortlist" options
|
||||
An IPv6 capable stub resolver based on the BIND 8 resolver
|
||||
code base and fully backwards compatible with existing BIND 8
|
||||
based resolvers is being developed and will be integrated into
|
||||
the BIND 9 distribution when completed.
|
||||
|
||||
- Forwarding of dynamic update requests; this is enabled
|
||||
by the "allow-update-forwarding" option
|
||||
This distribution already 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.
|
||||
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.
|
||||
|
||||
- A new, simplified database interface and a number of
|
||||
sample drivers based on it; see doc/misc/sdb for details
|
||||
|
||||
- Support for building single-threaded servers for
|
||||
environments that do not supply POSIX threads
|
||||
|
||||
- New configuration options: "min-refresh-time",
|
||||
"max-refresh-time", "min-retry-time", "max-retry-time",
|
||||
"additional-from-auth", "additional-from-cache",
|
||||
"notify explicit"
|
||||
|
||||
- Faster lookups, particularly in large zones.
|
||||
|
||||
BIND 9.1.0 also includes experimental implementations of a
|
||||
number of DNS protocols extensions still under development
|
||||
in the IETF. These include transparent processing of
|
||||
unknown RR types and use of the EDNS "DNSSEC OK" bit to
|
||||
explicitly enable DNSSEC processing in responses.
|
||||
|
||||
Cryptographic operations are now based on the OpenSSL
|
||||
library instead of DNSsafe.
|
||||
|
||||
Numerous bugs have been fixed.
|
||||
|
||||
BIND 9.1.0 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. Applications that use the BIND 8 res_*
|
||||
functions to perform DNS lookups or dynamic updates still need

BIND 9.1.0 is capable of acting as an authoritative server
|
||||
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 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.
