You'ld think that there should be some way to do a reverse DNS to determine from an ip the domains that exist on that ip. I suspect though that the whole internet fabric is designed the other way around, and that this information is probably something that no single registrar would know.
In theory, a reverse lookup could give you all the hostnames associated with that IP. In reality, almost no one actually sets up multiple reverse DNS records for such sites. So yes, it's difficult.
