MaxMind will be adding accuracy radius to the GeoLite2 City and GeoIP2 City databases as well as the GeoIP2 Precision City service.
The Accuracy Radius is an indication in kilometers of geolocation accuracy for the latitude and longitude coordinates we return for an IP address. The actual location of the IP address is likely within the area defined by this radius and the latitude and longitude coordinates.
As a reminder, the latitude and longitude coordinates we return for a given IP address are near either the population or geographic center of the most granular location data we return for that IP address (i.e., country, region/state, city, or postal code) and should not be used to identify a particular address or household.
For the binary databases and web service, this field will be available at
/location/accuracy_radius. All official GeoIP2 client APIs already support this field.
For the CSV databases, a new
accuracy_radius column will be added to the end of the IPv4 and IPv6 blocks files. Please test your integration to ensure compatibility before updating. You may test your integration by downloading the latest copy of the GeoLite2 CSV database, which already has the accuracy_radius column appended.
Target availability dates:
- GeoLite2 City – May 3, 2016
- GeoIP2 City – May 17, 2016
- GeoIP2 Precision City – May 19, 2016
