Would a tracert help track this down?

Apparently a "Layer 4 Tracert" is the most modern tool - http://pwhois.org/lft/index.who (I don't see a Winders binary, though). (via http://en.wikipedia.org/wiki/Traceroute )

Dunno if this IPTrace thingy would help either:

http://www.ip-adress...urgrandmother.com (shows up as SF).

HTH a little. Good luck.

Cheers,
Scott.
