NameSurfer 7.6.4.1


ALSO_NOTIFY records are used to define a set of name servers for a zone which for some reason should be notified if the zone is changed. This feature is useful for the servers which should have up to date information about the zone, but are not supposed to be know as authoritative name servers for the zone. For instance if you have backup DNS server in your organization which is intentionally not accessible form the external network and for this reason should not be specified as authoritative.

ALSO_NOTIFY record is only meaningful if it has the same name as zone SOA record. ALSO_NOTIFY record contains the name of server which should be notified when the zone is changed.

The support for ALSO_NOTIFY records is a NameSurfer extension. ALSO_NOTIFY records are not part of the DNS standards. Like other non-standard records, they cannot be retrieved by outsiders using DNS queries or zone transfers.
