With IP keyword in MSN search, you can find all the websites hosted on the same IP address. For example, do this search in MSN search [ip:210.52.223.105]. This is my blog’s IP, and you can find these websites hosted on the same IP.

There’re more sites. Hi neighbors!

There should be other method to do this thing, but this feature makes it much easier. I don’t know if we can do this in other search engines.
