AFAICT, the main challenge is to define what "parked" means in the
context of your application.
There seems to be DNSBL's for every other thing, I was expecting to find
one for parked domain names or the server IP addresses used.
This was for personal interest, rather than a commercial opportunity. I'm
a lousy typist and its unlikely change. But I can write computer
applications. I'd rather get a message my application can process
rather than relying on a human.
My preference is "legitimate" domain parking firms included a
standardized piece of meta-data my application could detect and use
as "this domain doesn't really exist." Sorta of a variant of the
web robots.txt file, but I prefer it to be application independent,
instead of assuming everything is HTTP Port 80. Perhaps start with a
standard record associated with the parked domain, i.e.
_notexist.example.com.
For less legitimate domain parking (i.e. typo-squatters), its a different
problem.
How about creating a database domain(domain_owner,domain_name)
and then querying by domain_owner. If the guy has more than 100 he looks
like a squatter and can me manually looked at.
e.g.

grep | wc says he has 51 lines. I guess it is 26 domains. The name suggests they are parked.

grep | wc says 3226 lines. But they are a famous german hoster. I dont think
they are squatting.
Just for curiousity AG is the german equivalent of PLC or SA in french.
I thought the namesevers would do. Maybe the whois gives more help.
Cheers
