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

  • /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.

Our Singapore server is live

October 10, 2017

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

Crimea accuracy update

September 27, 2017

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.

Mapping more mobile networks to regional level

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.

Removing additional anycast locations

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.

Removing anycast locations

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.

Spectrum rebranding

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.

GeoIP ISP Accuracy Improvements in Europe and Latin America

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
