The operation of the Incremental Zone Transfer response involves the server comparing the Serial number of the 'SOA' Record of the received message with the current serial number of the 'SOA' Record in the server. This comparison helps determine if there have been any changes in the zone data that require an incremental transfer.

In the Incremental Zone Transfer response, if there is a change detected in the zone data, the server has the option to reply with either the full data of the zone or with incremental data transfer. This allows for efficient data synchronization between the server and the client without transferring unnecessary information.
