[Geoip-general] Attaching degree of error to geolocation

[Thomas J M. <tjm...@ma...>]

The purpose of this message is to publish in a public forum a method of
attaching a degree of error to the estimated location of an IP address.

The geolocation database estimates the country, state or region, city,
postal code, latitude and longitude of an IP address.  Attached to this
is an estimate of distance between the actual location and the estimated
location based on the geolocation database entry for a specified IP
address.  The idea is that if you take any subset of the database, then
take the average of the distance between the actual location and
estimated locations based on IP address, this average should match the
estimate of distance also known as degree of error.
