<span class="command"><strong>update-policy</strong></span> rules that otherwise ignore the

name field now require that it be set to "." to ensure that any

was present, it wouldn't be interpreted as expected.

<span class="command"><strong>named</strong></span> now supports the "root key sentinel"
|
|
mechanism. This enables validating resolvers to indicate

which trust anchors are configured for the root, so that

information about root key rollover status can be gathered.

To disable this feature, add

<span class="command"><strong>root-key-sentinel no;</strong></span> to

Add the ability to not return a DNS COOKIE option when one

is present in the request. To prevent a cookie being returned

add <span class="command"><strong>answer-cookie no;</strong></span> to

<span class="command"><strong>answer-cookie no</strong></span> is only intended as a
|
|
temporary measure, for use when <span class="command"><strong>named</strong></span>
|
|
shares an IP address with other servers that do not yet
|
|
support DNS COOKIE. A mismatch between servers on the
|
|
same address is not expected to cause operational problems,
|
|
but the option to disable COOKIE responses so that all
|
|
servers have the same behavior is provided out of an
|
|
abundance of caution. DNS COOKIE is an important security
|
|
mechanism, and should not be disabled unless absolutely

|
necessary.

The end-of-life date for BIND 9.12 has not yet been determined.
|
|
However, it is not intended to be an Extended Support Version (ESV)
|
|
branch; accordingly, support will end after the next stable
|
|
branch (9.14) becomes available. Those needing a longer-lived
|
|
branch are encouraged to use the current ESV, BIND 9.11, which
|
|
will be supported until December 2021. See
|
