GeoIP2 Release Notes

More networks mapped to London boroughs

When a network geolocates to London, we will often return the borough for the city, rather than returning London. Beginning this Friday, June 9, we will be mapping more networks to London boroughs.

This change will apply to all products and services with city-level geolocation data:

• GeoIP City database
• GeoIP City Plus web service
• GeoIP Insights web service
• GeoIP Enterprise database

Issue Geolocating IPs in Portugal

We are aware of an issue in which our geolocation products and services are not returning correct city-level data for IP addresses located in Portugal.

The issue was introduced in our release of GeoIP databases last Friday, March 17. The issue has been fixed and will be corrected in the next release of our GeoIP databases, scheduled for Tuesday, March 21.

The following products and services are affected:

• GeoIP City database
• GeoIP Enterprise database

Web service customers will see the corrected data right away. Database customers should download the latest update to our databases to get access to corrected data.

Changes to MaxMind License Keys

We are making changes to the format of our license keys:

• New license keys will be longer, with a six character prefix.
• Beginning on March 27, 2023, we will no longer be issuing unhashed license keys for use with legacy versions of our GeoIP Update program (any version prior to v3.1.1).

For customers using our REST API, Client APIs or version 3.1.1 and higher of our GeoIP Update program:

No action is required. Existing license keys will still be valid and will continue to function normally.

New license keys will have the following changes:

• The character set is changing from [a-zA-Z0-9] to [a-zA-Z0-9_].
• The length of the license key will now be 40 characters.
• License keys will have a _mmk suffix.

Please note that the length of license keys may be increased in the future.

Customers using legacy versions of our GeoIP Update program:

Legacy versions of geoipupdate use less secure unhashed license keys. Beginning on March 27, 2023 we will no longer be issuing new unhashed license keys. Your existing license keys can continue to be used, but you will no longer be able to generate new unhashed license keys.

New license keys only work with geoipupdate version 3.1.1 or greater. We encourage you to update to the latest version at your earliest convenience.

Learn how to upgrade from geoipupdate legacy to the current version on our Developer’s Portal.
