I do wish people would get terminology right. DNS is hard enough
for the novice without using terms incorrectly.
It's the name of a "zone". It also happens to be a domain
name but in this case the constraint is because it the name
of the zone, i.e. it has SOA and NS RRsets (resource record
sets).
From the FAQ.
Q: I get error messages like "multiple RRs of singleton type" and
"CNAME and other data" when transferring a zone. What does this
mean?
A: These indicate a malformed master zone. You can identify the
exact records involved by transferring the zone using dig then
running named-checkzone on it.
dig axfr example.com @master-server > tmp
named-checkzone example.com tmp
A CNAME record cannot exist with the same name as another record except
for the DNSSEC records which prove its existance (NSEC).
RFC 1034, Section 3.6.2: "If a CNAME RR is present at a node,
no other data should be present; this ensures that the data for
a canonical name and its aliases cannot be different. This rule
also insures that a cached CNAME can be used without checking
with an authoritative server for other RR types."
