for canonical name
From The Free On-line Dictionary of Computing (30 December 2018) :
(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
and then type a hostname.
