.. namedconf:statement:: notify-cds
:tags: dnssec
:short: Controls whether ``NOTIFY(CDS)`` messages are sent on zone changes.
If set to ``yes``, DNS NOTIFY(CDS) messages are sent when the CDS or CDNSKEY
RRset changes. The messages are sent to the servers listed in the parent
zone's matching DSYNC records. A DSYNC record matches if the owner name under
`_dsync` subdomain of the parent zone corresponds to the given zone. For
example, the zone `child.example` should have a DSYNC record at
`child._dsync.example`. In addition, the RRtype field of the record must be
`CDS` and the Scheme field must be 1 (NOTIFY).
The default is ``no``. The :namedconf:ref:`notify-cds` option may also be
specified in the :any:`zone` statement, in which case it overrides the
``options notify-cds`` statement.
