The DNS server generally doesn't care what its name is.  It just looks up
names in the zone files.

If you want the server to give different answers depending on which
interface someone queries, you will have to run multiple named processes,
each with their own named.conf and zone files.  Each named.conf files will
contain a "listen-on" option that specifies the IP address of the interface
that the process should respond on.
