A zone transfer is the mechanism used by a secondary name server to fetch an up-to-date copy of its zone data from the primary. A zone transfer involves transferring all the records in the zone by means of a TCP network connection.

A secondary name server will perform a zone transfer whenever it finds that its zone data is out of date, based on comparing the SOA serial number of its own zone data with that of the primary.
