I am looking for a way that you, or anyone else, could indicate a domain

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.

From DNS nutshell or from the "DNS and BIND" book the programme

Can do.

In the IASON tools there is a hacked version

> chk1soa

error("","","","no soa").

IASON compiles on most flavours of unix including Mac OS-X and linux.

If you have an idea what is missing you are welcome to send me a private
