They are not really different. Only the name of the master server
(MNAME, says the RFC 1035) changes. It is a common practice to use the
name of the machine on which the zone file generator ran, so it may be
different between authoritative name servers. (Remember, for many
zones, primary/secondary name servers is a concept of the past.)
