The tool you’re talking about is sometimes known as a geographic traceroute or geolocation. It’s an interesting service, I’ve used one provided by Visualware called Visualroute a few times that is very impressive.

The problem is that the information is not always accurate. AOL addresses always show up as being from Virginia, my wireless card always shows up as Chicago and the information in these results is often misleading.

Furthermore, it doesn’t usually provide any necessary information. Knowing where a host is geographically can be better determined by looking at the host’s Web site and only would affect what law you use to report them.

It’s a neat trick but one I haven’t found a lot of use for.

However, the site you link to is very neat. It is extremely simple to use. I’ll have to keep it in mind should it become necessary.

Thank you for the tip!
