BIND 9.11.0 includes a number of changes from BIND 9.10 and earlier
releases. New features include:
* Added support for Catalog Zones, a new method for provisioning
Added support for Catalog Zones, a new method for provisioning
servers: a list of zones to be served is stored in a DNS zone, along
with their configuration parameters. Changes to the catalog zone are
propagated to slaves via normal AXFR/IXFR, whereupon the zones that
are listed in it are automatically added, deleted or reconfigured.
* Added support for "dnstap", a fast and flexible method of capturing
Added support for "dnstap", a fast and flexible method of capturing
and logging DNS traffic.
* Added support for "dyndb", a new API for loading zone data from an

external database, developed by Red Hat for the FreeIPA project.
* "fetchlimit" quotas are now compiled in by default. These are for the
"fetchlimit" quotas are now compiled in by default. These are 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
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
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
New stats counters have been added to count queries spilled due to
these quotas.

Added a new dnssec-keymgr key maintenance utility, which can generate
or update keys as needed to ensure that a zone's keys match a defined
DNSSEC policy.
* The experimental "SIT" feature in BIND 9.10 has been renamed "COOKIE"
The experimental "SIT" feature in BIND 9.10 has been renamed "COOKIE"
and is no longer optional. EDNS COOKIE is a mechanism enabling clients
to detect off-path spoofed responses, and servers to detect
spoofed-source queries. Clients that identify themselves using COOKIE
options are not subject to response rate limiting (RRL) and can
receive larger UDP responses.
* SERVFAIL responses can now be cached for a limited time (defaulting to
SERVFAIL responses can now be cached for a limited time (defaulting to
1 second, with an upper limit of 30). This can reduce the frequency of
retries when a query is persistently failing.
* Added an nsip-wait-recurse switch to RPZ. This causes NSIP rules to be
Added an nsip-wait-recurse switch to RPZ. This causes NSIP rules to be
skipped if a name server IP address isn't in the cache yet; the
address will be looked up and the rule will be applied on future
queries.
* Added a Python RNDC module. This allows multiple commands to sent over
Added a Python RNDC module. This allows multiple commands to sent over
a persistent RNDC channel, which saves time.
* The controls block in named.conf can now grant read-only rndc access
The controls block in named.conf can now grant read-only rndc access
to specified clients or keys. Read-only clients could, for example,
check rndc status but could not reconfigure or shut down the server.
* rndc commands can now return arbitrarily large amounts of text to the
rndc commands can now return arbitrarily large amounts of text to the
caller.
* The zone serial number of a dynamically updatable zone can now be set
The zone serial number of a dynamically updatable zone can now be set
via rndc signing -serial <number> <zonename>. This allows
inline-signing zones to be set to a specific serial number.
* The new rndc nta command can be used to set a Negative Trust Anchor
The new rndc nta command can be used to set a Negative Trust Anchor
(NTA), disabling DNSSEC validation for a specific domain; this can be
used when responses from a domain are known to be failing validation
