22.7 Dynamic Update of Zone Data
The term dynamic update refers to operations by
which entries in the zone files of a master server are added, changed, or
deleted. This mechanism is described in RFC 2136. Dynamic update is
configured individually for each zone entry by adding an optional
update-policy rule. Zones to update dynamically
should not be edited by hand.
Transmit the entries to update to the server with the command
nsupdate. For the exact syntax of this command, check
the manual page for nsupdate (man 8
nsupdate). For security reasons, any such update should be
performed using TSIG keys as described in Section 22.8, Secure Transactions.
