Sure enough, I used the same IP you used, and it worked! I had previously tried my IP address at home and at the office with the same result (Huntington Beach, California, USA), but if the IP isn't in the database provided, you just aren't going to see the geoip data. All that trouble because of a set of obscure IP address... Thank you for your patience through this!
I found this post on updating the geoip database:
So I'll update the database and maybe my obscure IP address will be found.
Thanks again!
