So far, so good...
I can collect the IP of the remote computer that's clicking on my pay-per-click ads (at least I think it's the remote computer, and not the IP of the server hosting my ads). I'll check that out.
Then I can do a Whois on DNSStuff.com to see where it came from.
Is there code that can do the Whois immediately, so I can store the location of the remote computer directly- rather than having to store the IP, and do it manually?
Obviously, I'm attempting to see if the PPC guys are padding my clicks. $
