canonical name
Technology Dictionary -> canonical nameSearch:
canonical name
(CNAME) A host's official name as opposed to an alias. The
official name is the first hostname listed for its Internet
address in the hostname database, /etc/hosts or the
Network Information Service (NIS) map hosts.byaddr ("hosts"
for short). A host with multiple network interfaces may have
more than one Internet address, each with its own canonical
name (and zero or more aliases).
You can find a host's canonical name using nslookup if you
say
set querytype=CNAME
and then type a hostname.
