Monthly updates to GeoNames data are incorporated into our databases as we refresh them. Above you will find a CSV report of these changes as they apply to English place names for the month of October as they relate to the following fields:

• geoname_id
• country_name
• country_code
• city_name
• subdivision_1_iso_code
• subdivision_2_iso_code

Note that the values for the old_ and new_ columns for a given field only differ for the field defined in the diff_in column.

* In this month’s update, a large number of geoname IDs have been updated for Brazil.

On Tuesday, October 22, 2024, we will release an improvement to our user count data to better detect IPs with multiple end users.

Many IP addresses with multiple end users that previously had a user count value of 0 or 1 will now have a value of 2.

If you have applications of the data that rely on user count values with a threshold of 0, 1, or 2, you may want to increase the thresholds by 1. For example, if you currently consider user count values of greater than 1 to be high volume, you may wish to consider user count values of greater than 2 to be high volume when this update goes live.

The following services will be impacted:

• GeoIP Insights web service

Learn more about user count data on our Knowledge Base.

Submit a support ticket request if you have questions or concerns.

Our IP geolocation databases released on Tuesday, August 13, 2024 will be significantly larger than our last release.

This increase in size is due to a new data source providing improved geolocation resolution for a large number of networks in Germany and Finland.

The following databases will be affected:

• GeoIP City database
• GeoIP Enterprise database
• GeoLite City database

Today, we are issuing an off-schedule release of the following GeoIP databases:

• GeoIP Enterprise database

We are correcting country-level information for a small number of networks associated with Microsoft Teams.

We are updating postal code data for the following major cities in Portugal:

• Amadora
• Portoand
• Vila Nova De Gaia

When an IP address is geolocated to any of these cities, the last three digits of the postal code will be set to 001. This change will be implemented over time, with some networks being updated starting on Tuesday, August 13, 2024, and more networks to follow.

The last three digits of postal codes are used in larger cities to provide geolocation information that is more specific than our underlying data allows for, so these digits will be set to 001. In more rural areas, the last three digits will be maintained.

The changes will be reflected in the following products and services:

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

There are two kinds of changes to expect.

First, we will update several popular ISP names to match their current naming and branding conventions:

Second, we will be updating the ISP name for a number of AT&T networks. About 1,000 (0.003%) AT&T networks in the United States will have an updated ISP name, either AT&T Internet or AT&T Wireless.

Updated AT&T networks will have corresponding updates to their connection_type value as well. For most networks, this will mean:

Please note that some AT&T networks may not have the corresponding connection type, because connection type values are dependent on additional signals.

These changes will be reflected in the following products and services:

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

* In this month’s update a large number of cities in Israel have improved place names.

In 2020, Norway merged a number of their subdivisions, but this proved unpopular and they have now unmerged these subdivisions. We have used the ISO subdivision codes for these subdivisions from before the 2020 change. The ISO subdivision codes we will be using for these subdivisions are reflected in this diff report.

To improve our server infrastructure and allow for better performance and efficiency, our API policies are now being permanently enforced as of March 13, 2024.

What are the policies?

• MaxMind only accepts API and database download requests sent with the more secure HTTPS protocol.
• MaxMind only accepts API and database download requests that are sent to the appropriate hostname as documented in the integration instructions on our Developer Portal (see direct links below).

What do I need to do? If you download GeoIP or GeoLite databases and you use an up to date version of our geoipupdate program, you do not need to take any action.

If you are using web services, or if you do direct downloads of GeoIP or GeoLite databases, you should ensure that you are using the correct hostname for your API requests, and that you are using HTTPS. Failure to do so will result in web service or database download requests failing.

You can view the appropriate URIs for GeoIP and GeoLite services and downloads on our Developer Portal using the links below:

• GeoIP Country, City Plus, and Insights web services
• GeoIP and GeoLite database downloads
• GeoIP Legacy web services
• GeoLite web services

Please note: This enforcement also affects minFraud API requests. If you are also a minFraud user, see our minFraud release note on this issue.

Due to irregularities in the latest GeoNames data, we will be maintaining the location names and codes from January. See the Monthly Diff Report for January 2024.

When the irregularities in the GeoNames data are resolved, we will update the data and post a new Diff Report.

To improve our server infrastructure and allow for better performance and efficiency, MaxMind will begin enforcing our policies around our API and database download requests March 13, 2024. To help customers get ready for this change, we will have a planned, temporary enforcement of these policies on February 7, 2024.

What are the policies?

• MaxMind will only accept API and database download requests sent with the more secure HTTPS protocol.
• MaxMind will only accept API and database download requests that are sent to the appropriate hostname as documented in the integration instructions on our Developer Portal (see direct links below).

What do I need to do? If you download GeoIP or GeoLite databases and you use an up to date version of our geoipupdate program, you do not need to take any action.

If you are using web services, or if you do direct downloads of GeoIP or GeoLite databases, you should ensure that you are using the correct hostname for your API requests, and that you are using HTTPS, prior to February 7, 2024.

If you have not made the requested changes before Wednesday, February 7, 2024, you might experience a period where web service or database download requests fail.

You can view the appropriate URIs for GeoIP and GeoLite services and downloads on our Developer Portal using the links below:

• GeoIP Country, City Plus, and Insights web services
• GeoIP and GeoLite database downloads
• GeoIP Legacy web services
• GeoLite web services

Please note: This enforcement will also affect minFraud API requests. If you are also a minFraud user, see our minFraud release note on this issue..

We will begin using R2 presigned URLs for all database downloads in order to increase the security and reliability of our services. Database download links and integration methods will not be changing.

What do I need to do?

MaxMind users who download databases should make sure that their HTTP client follows redirects and there are no proxy or firewall settings that would block requests to the host we are redirecting to. We will redirect requests using HTTPS on the following hostname:

• mm-prod-geoip-databases.a2649acb697e2c09b632799562c076f2.r2.cloudflarestorage.com

If you use a direct-download method (most CSV downloaders):

The permalinks for downloading databases will not be changing. You will be redirected from those permalinks to the R2 presigned URLs.

If you use geoipupdate (most MMDB downloaders):

We will be releasing a new major version that uses redirecting links. You can test your server configuration by updating to this new major version in a controlled environment before updating your version on production.

If you download directly from the account portal:

Check your firewall and browser security settings if you get errors when trying to download.

If you need more help:

Review our documentation on how to update and download databases.

The Anycast data point is now available in all CVS format databases—and, as announced in a prior release note, it’s also available in all GeoIP web services and all MMDB format databases.

In most cases, the addition of a new field to CSV databases should be a non-breaking change, but we recommend checking your integration to make sure that it can accommodate the addition of new fields.

The field is present in the following GeoIP databases:

• GeoIP Country database
• GeoIP City database
• GeoIP Enterprise database

GeoLite databases

The Anycast field has also been added to the CSV version of GeoLite geolocation databases, but the new field is intentionally blank. This allows the GeoIP databases to continue to be drop-in replacements for GeoLite databases, so that it’s easy to upgrade.

The field is present in the following GeoLite databases:

• GeoLite Country database
• GeoLite City database

Confirming your integration allows for new data points

The new field has been added to the Blocks CSV files: {GeoIP2,GeoLite2}-{Enterprise,City,Country}-Blocks-IPv4.csv and {GeoIP2,GeoLite2}-{Enterprise,City,Country}-Blocks-IPv6.csv

The new field name, is_anycast, has been added to the right of existing fields and the cell will either contain 1 (if the network is an Anycast network) or be blank (if it is not). The overwhelming majority of networks are not Anycast, and so this field will be blank in most cases.

If you’re not sure whether you’re using the MMDB format, the CSV format, or both, you can learn how to check your account’s database download history to determine whether you are downloading CSV files.

Please use the following example CSV files to test your integration:

• GeoIP Enterprise example files
• GeoIP City and Country example files

We have also updated our tutorials on importing GeoIP databases. Please see relevant links below:

• Importing to PostgreSQL
• Importing to MySQL
