We completed our most recent review and update of Geolocation for Crimea. Our accuracy has increased as follows:
Approximately 89% of website visitors who are from Crimea are currently located by GeoIP as being in Crimea. Approximately 97% of the visitors who are located in Crimea by GeoIP are actually in Crimea.
We currently locate Crimea in Ukraine, as we use GeoNames data and they locate Crimea in Ukraine. If GeoNames locates Crimea in Russia in the future, we will follow their change and post an announcement here as well as on https://twitter.com/maxmind.
In legacy GeoIP, we return a FIPS region code of 11 or 20. In GeoIP2, we return a iso code of 40 or 43 in the subdivision object.
Due to the nature of geolocation technology and other factors beyond our control, we cannot guarantee any specific future accuracy level. Further, accuracy figures are subject to change as IP networks are reallocated.

- We will be mapping additional mobile (cellular) networks to a region (subdivision) rather than city level. This change will only occur where the confidence in the city data is low due to the mobile provider allocating IPs over a wide area.

- We’ve updated the ISP and Organization data to replace the Charter Communications and Bright House Networks data points with the data point Spectrum, as these two ISPs have merged and been rebranded as Spectrum.

The GeoIP databases and services providing ISP and Organization data have been updated. The change is to a number of European and Latin Americans ISPs. We’ve updated the ISP name to use the common trade name instead of the legal name. This will make it easier to recognize the ISP.
Please note that if you use this data point, for example, to flag a visitor if they change ISP, you may need to adjust your implementation in order to avoid false positive flags.
The ISP name changes include the following:
Telefonica Movil De Chile S.A.to
Movistar Movil Chile
- November 8, 2016
We’ve updated any GeoIP database or service providing ISP and Organization data to return Comcast Business rather than Comcast Business Communications. We are doing so in order to use the trade name of the ISP and also because it is shorter.
Please note that if you use this data point, for example, to flag a visitor if they change ISP, you may need to adjust your implementation in order to avoid false positive or negative flags.
The following GeoIP databases and services are affected by this change:
- GeoIP2 ISP database
- GeoIP2 Enterprise database (Update will apply to November 15th release)
- GeoIP Legacy ISP and Organization databases
- GeoIP2 Precision and Legacy City Service
- GeoIP2 Precision and Legacy Insights Service
- September 15, 2016
- The GeoIP City databases now provide significantly improved accuracy for countries outside the US, especially China, India, and Japan. See more information about GeoIP accuracy on https://www.maxmind.com/en/geoip2-city-database-accuracy

- We are changing the latitude and longitude for two locations in our GeoIP and GeoLite databases. For IPs in the United States that we are unable to locate to a particular state or city, we will return 37.751, -97.822. For IPs that resolve to Ashburn, Virginia with zip code 20147, we will return 39.018, -77.539. We would like to remind customers that latitude and longitude values contained in the GeoIP databases are not precise and should not be used to identify a particular address or household.

We are updating the GeoIP ISP and Organization databases to return
Verizon Fiosinstead of
Verizon FiOS, due to a change in how Verizon capitalizes Fios. If you reference
Verizon FiOSin code or a custom rule, note that you may need to revise these references to
