Thanks, TigerShark,

I heard from someone else about my adding to such an old thread, too. I will watch out for that if I need to post again.

While I'm still interested in learning more about IP's, traceroute, and so on, I got a reply from IP2Location that was something more simple than I expected. It's also something to keep in mind when using IP tracers: they use user feedback in their data. Someone from Viet Nam claimed to be from Arizona. IP2Location says they are now working on a new approach to reduce wrong results in the database.

Thanks again,
