Every server has an IP address and using specialist websites, a list of domains which point to that IP address can be returned. Several websites do this, and many charge for the service.

If one types in a domain or IP address on myIPneighbors, the site lists other domains that point to that IP. It can be a little unreliable, though, no doubt due to the site’s heavy load.

I have already mentioned that this site does have practical uses. It’s interesting to see how packed your host’s server is, so you can see how good a deal you are getting, and what they are hosting. This could be useful as it’s something hosts rarely reveal but is very important to company’s reputations.

It could also make an interesting tool for doing investigations. Using it, you can see what projects companies are launching if they’re silly enough to put the domain on the same server.

Update: Site seems to be down for some time know, an alternative is DomainByIP
