AFAIK, Netcraft does not offer a reverse IP tool, i.e. a tool used to search by IP for all vhosts on a system. All I can see is a query which returns domains matched by the input string. If they *do* provide a true reverse ip tool, I would certainly like to see it. I like to test my results against similar services.
