Enables dynamic resource-record scavenging for the zone. Use
this feature to remove stale records that arise when clients are
configured to perform DNS updates, but do not delete their
entries when they are no longer valid. If the DHCP server
performs updates, it also delete records when client leases
expire. Scavenging should not be enabled on these zones.
scvg-ignore-restart-interval rangetime(2h-24h)
Ensures that the server does not reset the scavenging time
whenever a server restarts. Within this attribute set,
Network Registrar ignores the time between when a server went
down and the time it restarts. This interval is normally short.
The value can range from two hours to one day.
With any time longer than the set time, Network Registrar
recalculates the scavenging period to allow for record updates
that cannot take place while the server is stopped. You can also
set this attribute on a zone, and the value set on the zone
overrides the server setting.
scvg-interval rangetime(60m-1y)
Sets the seconds that DNS waits before removing (scavenging)
out-of-date resource records.
scvg-max-records rangeint(1-10000)
Controls the maximum number of records to search at one time for
candidates to be scavenged.
scvg-max-records-searched int
Sets the maximum number of records to be scavenged from the zone
during a scavenging interval.
scvg-no-refresh-interval rangetime(60m-1y)
Sets the number of seconds during which DNS updates cannot increment
the zone timestamp.
scvg-pause-interval rangetime(1s-24h)
Controls the interval (in seconds) that scavenging will wait
after scavenging a set of records, before going onto the next
set.
scvg-refresh-interval rangetime(60m-1y)
Sets the number of seconds during which DNS updates can increment
the zone timestamp. After both the no-refresh and refresh intervals
expire, the record is a candidate for scavenging. The value
can range from one hour to 365 days. The zone setting overrides
the server setting of 604800s (1w).
serial int
Sets the starting serial number of the zone. A DNS server uses
a serial number to indicate database changes. Increments to this
number trigger zone transfers to a secondary server.
soattl dnsttl
Controls the ttl value applied to a zone's SOA resource record.
