The other problem is that what you want to do is more or less impossible without having the list of actual domains that they claim to host. http://dougbarton.net/bind-users/FAQ.html#DelegationList OTOH, if you have the list, you can recursively query for the information that satisfies the definition of "hosting" that you come up with.
