from local addresses. (Previously, other addresses
were allowed so long as updates were signed by the
local session key.) [RT #45492]

|
|
<para>
|
|
ICANN is in the process of introducing a new Key Signing Key (KSK) for
|
|
the global root zone. BIND has multiple methods for managing DNSSEC
|
|
trust anchors, with somewhat different behaviors. If the root
|
|
key is configured using the <command>managed-keys</command>
|
|
statement, or if the pre-configured root key is enabled by using
|
|
<command>dnssec-validation auto</command>, then BIND can keep keys up
|
|
to date automatically. Servers configured in this way should have
|
|
begun the process of rolling to the new key when it was published in
|
|
the root zone in July 2017. However, keys configured using the
|
|
<command>trusted-keys</command> statement are not automatically
|
|
maintained. If your server is performing DNSSEC validation and is
|
|
configured using <command>trusted-keys</command>, you are advised to
|
|
change your configuration before the root zone begins signing with
|
|
the new KSK. This is currently scheduled for October 11, 2017.
