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 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?

No this is not possible.
You can only find all PTR entries for the IP but if the guy only add one PTR record you will only get one domain.
