To create a new reverse DNS zone on the hosting appliance, fill in the fields on this page and click Add.
To add a master zone, specify the network's IP subnet mask. In most cases the network administrator will provide this. You can also change the values for refresh, retry, expire, and minimum time-to-life (TTL).
To add a slave zone, select Slave Zone, and then type in the name of the master server.
If you are not sure whether you need to provide reverse DNS service for this network, talk to the network administrator. For more information about adding DNS zones, refer to the Online Guide.
