Of course, the location information is just an informed estimate. Just as "on the internet, no one knows you are a dog" on the 'net, no one really knows where an IP address is.
This may improve when IPv6 is widespread, but NATs to a great job of obfuscating location.
More importantly, sometimes, the network doesn't do what you expect. A while ago, I worked for a worldwide consulting company. When I was in their Dusseldorf Germany office, I noticed that the IP addresses were part of their Fairfax VA (USA) office. And with a little investigation, the main, fastest link was a T1 from Germany to the US. So the IP address's geolocation was off by a few thousand miles, a major ocean, and several international borders.
