Cricket and Mats answered already.
The important thing to be aware of is that there aren't any
different types of domain based upon their names - all domains
are created equal, and remain equal. Any domain can have any RR
in it. Any time you're tempted to generalise based upon domain
name, you're almost invariably going to be wrong.
The only significance the various domain name trees have is how
one registers in them (what the various registrars will allow to
be registered there) and what lookups are conventionally directed
to them (as a first resort, a CNAME (or DNAME) can then point you
anywhere).
Technically, everything that applies to one domain applies to every domain
(with the root domain as the one and only special case).
