(Home >> DNS Functions >> Synchronize DNS Records)


This feature is useful if you use a DNS cluster, but some servers in the cluster respond to DNS queries with outdated information. This feature compares zone files among servers, recognizes which are the most up-to-date, and updates the servers in the DNS cluster.

For more information about how to set up a DNS cluster, read our DNS Cluster documentation.

Synchronize records

Before you begin the synchronization, consider the following questions:

  • Do you want to synchronize all of the domains’ zone files, or just one zone file?
  • Do you want to update all of the servers in the DNS cluster, or just this server?


To synchronize DNS records, perform the following steps:

  1. Select the type of synchronization that you wish to perform:
  2. If you selected Synchronize all zones to this server only or Synchronize all zones to all servers, select the associated Synchronize zones that are not configured on this server checkbox to copy updated versions of all zone files to this server. The system copies all of the zone files, regardless of whether they are local to this server.
  3. Click Synchronize.
