Slave server records are used to define slave DNS servers that mirror this zone. To maintain synchronization, when a change is made to this DNS zone, all sites listed in the slave server records will be notified.

A default Slave server record, usually named "dns.zonename," is created so that, if this zone is mirrored to a slave server, it will be able to communicate with the master server to maintain synchronization.

Click Add to create a slave server record.

To remove a slave server record from the list, click the box next to that slave server and click Delete.
