Finding all domain names that resolve to the same ip?
I am trying to find out if a dedicated server at a hosting site I am using has more than one domain pointing to it through DNS. Is there a way to do a reverse DNS lookup with my host's IP address such that I can get a list of all domains resolving to my host's IP? For example, say my host's IP is 1.2.3.4. There can be multiple domains that resolve to the IP. Is there a way to tell if there is more than just my domain resolving to that IP?
