title: How can I find all the domain names that resolve to one ip address?
body: <p>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.</p>
  
  <p>Is there any way to take an ip address and get a list of all the domain names that resolve to that ip?</p>
