You are describing a ZONE and are calling it a domain. That in

yep.

Erh, check that.

A zone is *not* a domain.  A zone is a portion of the DNS tree.  A
zone has a root at a particular domain name, but it isn't a domain.
A zone includes all records within that portion of the DNS tree.

This definately is a more complete answer.  However, to be
accurate, it needs an addition: A zone does _not_ include
the portion of the DNS tree that is delegated again.

I should have written something in the line of: A zone name
is a domain.
