Don't parked domains exist on a registrar owned IP?  I would think a 
list could be built from spending some time contacting each registrar 
(http://www.icann.org/registrars/accredited-list.html). ;-)

Or if you didn't mind over-compensating, you could at least assume that
"Various Registrars" listed here: 
http://www.iana.org/assignments/ipv4-address-space will probably contain 
the registrar's public sites as well as hosted domains.  Just my $.02
