Bind dynamic updating zone records
With dynamic update, on the other hand, the primary server for the zone can also be configured to support updates that are initiated by another computer or device that supports dynamic update.
For example, it can receive updates from workstations registering A and PTR resource records, or from DHCP servers.
You can put this key into “/etc/rcnd.key” or save the output and add it to the configuration files.
After all prerequisites are met, the zone's primary server can then proceed with an update of its local zones.To build upon these two post will will introduce Dynamic DNS into the mix.With Dynamic DNS we can modify or add records to DNS dynamically based on DHCP leases that are provided.Multiple updates can be processed concurrently only if one update does not depend on the final result of another update.In previous post we configured Bind9 as a DNS Server as well as configured a HA DHCP Cluster.
