I host my website on shared hosting. My connection is too slow and unreliable to justify running my own server and I have no need to hire a dedicated server or a VPS. Consequently, many other websites are hosted on the same box as mine and I have often wondered their nature. In addition to curiosity, this could be used to check to see you agree with the ethical stance of your webhost, to check to see if any of the other sites drain resources (thus slowing your site) and to check for any possible security risks.
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
To use the service, simply enter the IP address of your website if you know it, or the domain name to look up the IP address instead. Once you do that, you get a list of web sites that are hosted on the same IP address which usually is a good indicator that they are also hosted on the same server as your website.
