Concept

Process for synchronizing DNS zone data between master and slave servers

Zonentransfer

The zone transfer is a process in which DNS zone data is synchronized between a primary (master) and secondary (slave) DNS server. This enables redundancy and load distribution in DNS operation by having multiple servers provide the same DNS zone. Zone transfers are typically performed over TCP port 53 and require special configurations to prevent unauthorized data collection.
