Tracker IP Question Concerning Earthlink

I know that IP addresses aren't always completely accurate, but I have a question.

I've tracked an IP for someone who is using Earthlink. The IP came up as located in Jacksonville, Florida (Earthlink's main office is in Atlanta), yet the person is supposed to be in northern Alabama, almost 9 hours away from Jacksonville.

Do any of you have knowledge of Earthlink & how accurate it is in trackers? Is it possible that it's just routed through Jacksonville, or is it likely that they are in the Jacksonville area? The IP didn't come up as a hotel or other public area. I know sometimes IPs come up from neighboring states, but this seems quite far from the supposed location.

Thanks!

Earthlink IPs are very similar to AOL (they use the exact same technology) You can be in another state, or even across the country and still come up in one of (i think its 9 ) locations that earthlink routes all IPs through. So the bad news is, its terribly inaccurate for getting the locations of visitors.
