If you need to quickly determine your public IP address, try out this site from onedown.net. I have used Gnomedex's contact form to quickly determine my public IP address before I found onedown.net.

It appears that all the links listed above are not working. So I tracked down some new ones. You could always search google or yahoo to find others.

  1. IP Info
  2. IP Finder
  3. IP Chicken
  4. IP Finder

After you identified an IP address, you can use additional tools to find the owner of that address.

  1. Sender Base
