How can I find all the domain names that resolve to one ip address?

Question

Lately I've been tracking a spammer on craigslist. I recently discovered that he's added a new technique to his arsenal, he registered a whole bunch of domain names but they all resolve to the same ip address.

Is there any way to take an ip address and get a list of all the domain names that resolve to that ip?

Oh, actually you can. After all, if there are companies constantly indexing the whole www, or even making a "backup" of it, why wouldn't be possible to index information about domains and IPs?

There are some free services that do that: You provide a public IP address, and you get a list with the domain names that resolve to it.

This can be quite useful for several purposes. Tracking a spammer seems to be one of them.

I don't know how accurate, current or complete is the information that these services provide, but they have helped me in dealing with situations like the one you described.

You can try tool http://alestat.com/hosted_ip,,,1.html Also you can define range of IP adress.

Reverse DNS will only allow one record per IP-address

I'm no expert on this, but according to the WP link I provided, it is possible to have more than one record per IP adress, but not usual.
