Flushing a zone refers to deleting all ADNR-managed resource records from an ADNR-managed zone. Flushing a zone is not a normal occurrence, but might be a useful administrative tool in certain situations. You can flush all zones, or just specific zones.
Flush all zones by removing all host_group and server_group statements from the ADNR configuration file and issuing a MODIFY REFRESH command. You might flush all zones when resource records are inadvertently orphaned in a name server. The orphans can be removed by ADNR by restoring a copy of the previous configuration file, removing all host_group and server_group statements, and then issuing a MODIFY REFRESH command. When the command has completed, you can issue another MODIFY REFRESH command using the latest ADNR configuration file to return to the configuration that you want to use.
You flush individual zones in much the same way as you flush all zones. Instead of removing all host_group and server_group statements from the ADNR configuration file, you remove only those statements that reference the zone or zones that you want to flush.
