Whats that tool where you can find which domains are on an i.p????
 

I am looking for a tool where you can type in a domain and it gives you all the other domains which share the i.p.
I cant even think of the name, I think my brain is flat at the moment, could someone help a newbie out and post me a link please?
Thanks
