My home IP address is officially registerd to a proxy server in San
Diego. I'm connected via satellite behind the proxy from a very remote
location in northern California, and yet the findme utility properly
identified my actual geographic position. The satellite service provider
has -not- revealed my actual address. ( I checked with friends in their
net ops center.) The data for local.live.com was purchased from a
commercial ip geolocation service who determined my actual, rural
location using undisclosed mechanisms.
