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_size in 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_provider are now deprecated in GeoIP2.
Due to the increased coverage by mobile carriers, very few satellite providers
now serve multiple countries. As a result, the
does not provide sufficiently relevant data for us to maintain it.
GeoIP2 Insights web service now offers
population_density fields within the
represents the weighted average income in US dollars per person for the zip
code(s) associated with the IP address.
population_density represents 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 web services API
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.
We've enhanced the GeoIP2 City Plus and GeoIP2 Insights web 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.
