The master DNS server can be a primary or secondary DNS server. This is how DNS builds its resilience on the Internet. A DNS zone transfer is a process where a primary DNS server sends a DNS zone data to a secondary DNS server.
Of a zone and secondary DNS servers keep copies of the zone for redundancy. A master DNS server is the source of the zone information during a transfer. Check the Enable Zone Transfer box and either select to use the default zone transfer interval inherited from the primary DNS Server settings or enter a specific value here.
Zone transfer is achieved by copying the zone file from one DNS server to a second DNS server. DNS servers within a domain are organized using a master-slave method where the slaves get updated DNS information from the master DNS. While DNS zone transfers are perfectly fine between DNS servers intended to share zones information they could leak a lot of information that would otherwise not be available to an attacker.
