Geolocation database
A lookup table that maps IP ranges to a guessed country and city.
Sites decide where an address is by consulting a database such as those sold by commercial vendors. These databases disagree with each other and lag behind changes.
If a target relies on one database, test against that one. An address can be in one city and be labelled as another.
