GeoIP2 - Perl API for MaxMind's GeoIP2 web services


version 0.0200


This is an alpha release, and APIs may change before the final production release, which will be numbered 2.0000.

This distribution provides an API for the GeoIP2 web services (as documented at http://dev.maxmind.com/geoip/geoip2/web-services).

In the future, this distribution will also provide the same API for the GeoIP2 downloadable databases. These databases have not yet been released as a downloadable product.

See GeoIP2::WebService::Client for details on the web service client API.


GeoNames (http://www.geonames.org/) offers web services and downloadable databases with data on geographical features around the world, including populated places. They offer both free and paid premium data. Each feature is unique identified by a geoname_id, which is an integer.

Many of the records returned by the GeoIP web services and databases include a geoname_id field. This is the ID of a geographical feature (city, region, country, etc.) in the GeoNames database.

Some of the data that MaxMind provides is also sourced from GeoNames. We source data such as place names, ISO codes, and other similar data from the GeoNames premium data set.


If the problem you find is that an IP address is incorrectly mapped, please submit your correction to MaxMind at http://www.maxmind.com/en/correction.

If you find some other sort of mistake, like an incorrect spelling, please check the GeoNames site (http://www.geonames.org/) first. Once you've searched for a place and found it on the GeoNames map view, there are a number of links you can use to correct data ("move", "edit", "alternate names", etc.). Once the correction is part of the GeoNames data set, it will be automatically incorporated into future MaxMind releases.

If you are a paying MaxMind customer and you're not sure where to submit a correction, please contact MaxMind support at for help. See http://www.maxmind.com/en/support for support details.


This module uses semantic versioning as described by http://semver.org/. Version numbers can be read as X.YYZZ, where X is the major number, YY is the minor number, and ZZ is the patch number.


MaxMind has tested this API with Perl 5.8.8 and above. Reasonable patches for earlier versions of Perl 5.8 will be applied. We will not accept patches to support any version of Perl before 5.8.

The data returned from the GeoIP2 web services includes Unicode characters in several languages. This may expose bugs in earlier versions of Perl. If Unicode support is important to you, we recommend that you use the most recent version of Perl available.


Please report all issues with this code using the GitHub issue tracker at https://github.com/maxmind/GeoIP2-perl/issues

If you are having an issue with a MaxMind service that is not specific to the client API please see http://www.maxmind.com/en/support for details.
