The use a different geoIP database.
GeoIP is like cup-and-string level technology.
It is literally a database that is just “this is IP is located at X” and updating the locations is basically on the honor system. It is further complicated by the fact that the largest GeoIP databases refuse to update the locations of IPs that are associated with VPN servers, which makes their databases even less accurate.
Different geolocation service providers apply different algorithm to determine the location. There is no one database providers are claiming their database is 100% accurate due to frequent re-allocation of the IP address range. Therefore, you can expect different results among providers. Below is the accuracy table published by one of the providers, IP2Location.
