One of the Twitter people – @mrhomegadgets, I’m following pointed to a site that shows you where an IP address is located. The site has a Google map on the world and a text box called ip:2:loc where you type in any IP address on the internet. It immediately pops up a red push pin on the geographical location of the IP address. I typed in my IP address and it produced the map below. It also correctly listed my ISP and the physical location of the ISP.
