John- You could use http://www.ip-adress.com/ipaddresstolocation/ to do this. Including the IP with the URL would make this easy to script for hundreds of addresses, like this: http://www.ip-adress.com/ipaddresstolocation/?QRY=35.8.2.3 Hope this works for you, Matt On Thu, Nov 20, 2008 at 7:46 AM, John Williamson <[log in to unmask]> wrote: Does anyone know of a method for looking up the geographic location (country, state) for a list of IP addresses? It would be a large list, so I need a solution that could accommodate hundreds or more addresses, which rules out doing this one at a time manually.
