- Effective May 9, 2017, we are providing a GeoLite2 ASN database in a CSV format suitable for importing into a SQL database as well as a GeoLite2 ASN database in our MaxMind DB binary format. You can download the database here. GeoLite2 databases may also be downloaded and updated with our GeoIP Update program.
- May 8, 2017
- Effective May 7th, 2017, we are updating 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.
- March 5, 2017
Effective March 5th, 2017, we’ve updated GeoIP databases and services providing ISP and Organization data. 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
Effective November 8th 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
- Starting with the July 31st 2016 build, the GeoIP City databases 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

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_radiuscolumn 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
- April 11, 2016
- Effective April 12th, 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.

Effective March 1st, 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

MaxMind has released libmaxminddb 1.1.2, which includes a number of important security fixes. Among these fixes is improved validation of the database metadata. Unfortunately, MaxMind GeoIP2 and GeoLite2 databases created earlier than January 28, 2014, had an invalid data type for the
record_sizein the metadata. Previously these databases worked on little endian machines with libmaxminddb but did not work on big endian machines. Due to increased safety checks when reading the file, these databases will no longer work on any platform. If you are using one of these databases, we recommend that you upgrade to the latest GeoLite2 or GeoIP2 database.

- We are updating the GeoIP ISP and Organization databases today to return AT&T Internet Services instead of BellSouth.net, due to a merger with AT&T. We are renaming Bouygues Telecom Division Mobile to Bouygues Mobile. There is also a bug fix to return Frontier Communications instead of AT&T Wireless for Frontier customers in Connecticut.

is_satellite_providerare now deprecated in GeoIP2.
Due to the increased coverage by mobile carriers, very few satellite providers now serve multiple countries. As a result, the
is_satellite_provideroutput does not provide sufficiently relevant data for us to maintain it.

GeoIP2 Precision Insights service now offers
population_densityfields within the
average_incomerepresents the weighted average income in US dollars per person for the zip code(s) associated with the IP address.
population_densityrepresents the weighted population per square kilometer for the zip code(s) associated with the IP address. Note that these fields are returned for IP addresses located in the US only. These new fields are documented in the GeoIP2 Precision Web Services API documentation.
- June 11, 2015
- We’ve released the GeoIP2 Anonymous IP, ISP, Domain and Connection Type databases in CSV format. All GeoIP2 databases are now available in this format.
- May 11, 2015
- We’ve enhanced the GeoIP2 Precision City and GeoIP2 Precision Insights services to identify the organization associated with a business IP address in 10% more instances.

We are working on improving the accuracy in Crimea.
Approximately 60% of website visitors who are from Crimea are currently located by GeoIP as being in Crimea. We plan to increase this to 75% in the next couple of months.
Approximately 95% 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.
