Finding all domain names that resolve to the same ip?

Solution 1:

Bing can search on IP address, which tends to work for me.

For example, searching for other things hosting with myipneighbors.com

ip:74.208.74.176

Returns:

http://www.bing.com/search?q=ip%3A74.208.74.176
myipneighbors.com
hotelir.com

Solution 2:

No.

It's not the way DNS works. You can register any number of domains against a single IP, and not bother putting in a reverse DNS entry for any of them if you want.

Unless you want to brute force resolve the internet. :)

Solution 3:

Yes. There is. It's not 100%, but it certainly works well enough.

There are other tools that do this sort of thing as well, but this will get you going.

Solution 4:

Check out www.myipneighbors.com, it is mostly designed to help people on shared hosting know what other domains are on the same server, but it sounds like it would also apply to what you are trying to do.
