A method for accurately determining the geographic location of a PC or other networked device on the Internet. Client software furnished by a service provider performs trace-route or other network analysis commands to known servers (e.g., eBay, Yahoo, Amazon) or even servers at random locations. The client collects an array of IP address and other network information as a result of the trace-routes, and the trace-route IP information is then transmitted to the service provider that is trying to identify the geographic location of the client. Using the array of IP addresses thus generated, the Internet server software can analyze location information of each Internet hop within each trace-route. For example, the server might look at the first five hops from the client to the server. If four of the five routers have addresses within the geographic area of interest, the server can conclude that the client is probably within the geographic area.
