Refreshing zones

When the data in the master zone file is updated, the copies of the zone file on the slave servers must be updated. To enable updates to happen automatically, the master zone must be configured to propagate changes to the slave zones. This is typically done by configuring the allow-transfer attribute in the master zone configuration file. The slave servers authorized to receive updates refresh their copy of zone information when the expiry interval specified in the SOA record for the zone is reached or when they receive an update notification from the master server. Alternatively, you can initiate a zone update when you need to synchronize the master and slave copies.

To refresh a zone:

1. In the shortcuts section of the Home page
   , click Zones (DNS section).

2. In the Zone List form, locate the zone you want to refresh and in the Actions column, click . The zone information is updated.
