You might be able to use lack of an SOA record as a hint.  In my
experience, parked domains often do not have SOA records because
the parking companies are lazy.  It is a lot easier to put all the
parked domains in a parent zone file, or even use a wildcard, rather
than have a zone file for each parked name.
