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

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

- 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

- 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

- 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.

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.

As part of our ongoing work to return more data, MaxMind has increased the number of IP addresses that map to a postal code.
An ISP may allocate an IP range over multiple postal codes. In such cases, MaxMind cannot accurately determine the exact postal code associated with an IP address in that range. Previously we only included a postal code if we were confident of the resolution. Now, we include more postal codes, returning a postal code within a 50km radius.
We are doing this as a convenience to our customers who want to use the postal code instead of the city to link to other data.
In addition, we’ve added Poland and Portugal to the list of countries for which we return postal codes. The full list of countries for which we provide postal codes now includes the following:
Argentina, Australia, Austria, Belgium, Brazil, Bulgaria, Canada, Croatia, Czech Republic, Denmark, Finland, France, Germany, Hungary, Iceland, India, Italy, Malaysia, Mexico, Netherlands, New Zealand, Norway, Pakistan, Poland, Portugal, Russia, Slovakia, South Africa, Spain, Sweden, Switzerland, Thailand, United Kingdom, United States.

We have improved the coverage and accuracy for GeoIP City in Japan, South Korea and Venezuela. We expect to make further improvements to the accuracy in South Korea over the next few weeks.
If we are unable to determine the city or region for IP addresses in Argentina, Austria, Bangladesh, Belgium, Bulgaria, Brazil, Canada, Chile, Colombia, Czech Republic, Denmark, Egypt, Spain, Finland, Greece, Hungary, Indonesia, Ireland, Iran, Netherlands, Norway, Peru, Philippines, Poland, Portugal, Russia, Sweden, Thailand, Turkey, Ukraine, we will return a latitude and longitude of the largest city in the country.

- MaxMind’s most accurate IP geolocation data – GeoIP2 Precision data accurately geolocates 5% more IPs to postal codes and 3% more IPs to cities than GeoIP Legacy data
- Location names in eight popular languages
- Support for IPv6 addresses

On August 11, 2014, we will discontinue serving requests to port 8010. If you use this port, we ask that you:
- Replace calls to maxmind.com, port 8010 (http://maxmind.com:8010/) with calls to geoip.maxmind.com port 80 (http://geoip.maxmind.com/) or port 443 (https://geoip.maxmind.com/). We strongly encourage using HTTPS since this will encrypt your license key and the IP address you are looking up.
- Upgrade to the GeoIP2 web service, which offers more accurate city and postal code data. There is no extra cost and you can use your existing user ID and license key to access. For details on how to call the GeoIP2 web service, see our developer page.
In addition, on August 5, we will disable the web services on port 8010 for one hour starting at 1 p.m. UTC.
Please email us at email@example.com if you have any questions.

We’re excited to roll out IPv6 access for our web endpoints over the next few months. The rollout will be gradual to ensure a minimum of disruption for clients. We will be adding AAAA records for hostnames on the dates specified below. Most clients aren’t yet using IPv6 and should notice no issues. Clients with properly configured IPv6 should also notice no issues. If you have any questions or issues, please email us at firstname.lastname@example.org.
The AAAA address for US West servers will be 2607:f0d0:3:7::4.
The AAAA address for US East servers will be 2607:f0d0:3:8::4.
