Which simply proves that geolocation based on IP address is crap.

However, should you be using a laptop (let alone mobile) with wifi,
there are tools/databases that people can use which will quite likely
locate you within a few hundred yards.

I don't think you mean with wifi do you? Locating a laptop on wifi
should get you no further information that the IP address of the router
providing the wifi. The same information that you would get for a wired
machine on the same lan.

A laptop on 3G mobile data however may well be be located more accurately.


Google collect(ed) wireless nats with their streetview cars, and
combined it with addresses. For a time it was possible to get that info
from their database.

There are companies that can locate mobile phones and for a short time
one website did it for free.
