Geolocation by IP Address (Linux Journal) [LWN.net]

Linux Journal posits that determining geographic locations based on Internet IP address can be useful. "Geolocation by IP address is the technique of determining a user's geographic latitude, longitude and, by inference, city, region and nation by comparing the user's public Internet IP address with known locations of other electronically neighboring servers and routers. This article presents some of the reasons for and benefits of using geolocation through IP address, as well as several techniques for applying this technology to an application, Web site or user community."

It doesn't work well with corporate users, because users at widely dispersed locations can appear to be coming from the same point, that is, from wherever the corporate gateway is located.

Good databases contain such information. Apart from many corporations having multiple proxies at their locations.

A really cool example (for germany) is at

Unfortunately, their database is not free.

Sorry, if the corporation does not wish to publicize the location of its employees, there is no magic that can reveal where an employee who is using a proxy is really coming from.

For those interested with that, about a month ago, I wrote a very small Java library that uses different Geo Internet services to provide you with location information. It's really basic, but it works for me.
