Release Notes for GeoIP2 Web Services

November 2, 2017

GeoIP2 Precision Insights now includes anonymizer-type outputs. These outputs are:

  • /traits/is_anonymous – whether the IP address belongs to any sort of anonymous network.
  • /traits/is_anonymous_vpn – whether the IP address belongs to an anonymous VPN system.
  • /traits/is_hosting_provider – whether the IP address belongs to a hosting provider.
  • /traits/is_public_proxy – whether the IP address belongs to a public proxy.
  • /traits/is_tor_exit_node – whether the IP address is a Tor exit node.

Please see our GeoIP2 Precision Web Services documentation for more information.

October 31, 2017
We have discontinued the legacy GeoIP JavaScript services, which used the endpoints http://js.maxmind.com/js/country.js and http://js.maxmind.com/js/geoip.js.

If you still have not upgraded your integration to use the GeoIP2 JavaScript Client API or are encountering problems with your legacy GeoIP JavaScript services, you can find more information about what to do by clicking here.

Our Singapore server is now live. GeoIP2 Precision and GeoIP web service customers – if you hardcode any of our IPs in your application or your firewall, please make sure you have added the new server IP addresses to your list:

  • IPv4 address: 169.55.62.55
  • IPv6 address: 2607:f0d0:3:2d::4
  • hostname: geoip-as-southeast.maxmind.com

    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.

    August 17, 2017
    On October 31, 2017, we will discontinue our legacy GeoIP JavaScript services, which use the endpoints http://js.maxmind.com/js/country.js and http://js.maxmind.com/js/geoip.js. Please upgrade your legacy GeoIP integration to use our GeoIP2 JavaScript Client API before that date.

    July 24, 2017
    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.

    July 10, 2017
    The geographical location for anycast CloudFlare networks: 104.16.0.0/12, 162.159.0.0/16, 190.93.244.0/22, 198.41.192.0/19 have been removed.

    June 23, 2017
    Our Account Portal has been updated to include the ability for our customers to create and manage multiple license keys.

    June 11, 2017
    We are removing the geographical location for the anycast CloudFlare network 141.101.112.0/20. Anycast networks can be routed to a number of different locations all around the world, typically based on what is the nearest location. Over the next few weeks, we may remove the geographical location for additional anycast networks, including more CloudFlare networks as well as Google public DNS servers 8.8.8.8 and 8.8.4.4.

    Our GeoLite2 ASN database is now provided 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
    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.

    March 5, 2017

    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:

    • Proximus Skynet to Skynet Belgium
    • Telefonica Germany to O2 Deutschland
    • Telefonica Movil De Chile S.A. to Movistar Movil Chile
    • Tele Danmark to TDC Danmark
    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

    April 26, 2016

    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
