I have a shared hosting account and I would like to see what other sites are on that server. I know there is a website like that, I've seen it before on Digg, but I cant find it. If anyone knows of that site I'm talking about, that would be great!!!!

Thanks

This will do it:

http://www.seologs.com/ip-domains.html

... but the list is not exhaustive. I host a dozen domains and a dozen more subdomains on one IP address, and it only knew about half of them.
