Coming from the CDN land this isnt true. We didnt put too much effort in to precision, but on the order of 99% of IP addresses get down to metro area. Cheap commerical providers like Maxmind get to the right postcode on the order of 90-95% of the time. Building your own latency and peering maps bridges that gap to 99% or better. Simply based on network topology and latency we should be able to get you down to post code or general area of a city.
