Yesterday while I was looking at Digg.com, I found a very interesting little online tool. By simply entering in a domain name (or an IP), it allows you to see all other domains on that same IP. Although it’s not entirely accurate (which I can attest from my own personal testing), it does a decent job. Better than any other such tool I’ve seen before. I also found it seems to be more accurate for older domains.

In any case, it’s another tool that’s good to have in your arsenal
