GeoIP2 Connection Type Databases
Determine the connection type of your visitors based on their IP address. The database identifies cellular, cable/DSL, and corporate connection speeds.
To learn more about the GeoIP2 Connection Type database, including terms and pricing, please visit the GeoIP2 Connection Type Database page.
Data Privacy
To comply with data privacy regulations, please monitor our Do Not Sell My Personal Information Requests page (login required) for IP addresses and networks that should not be used for advertising or marketing purposes. You can automate retrieval of this list using our privacy exclusions API.
Binary Database
Binary databases make use of the MaxMind DB file format. MaxMind provides official client APIs in the language listed below. The following client APIs are open source and licensed under the Apache License, Version 2.0.
You can also use the mmdbinspect tool (in beta), a command line interface built with Go, to look up one or more IPs from one or more MMDB databases and receive output in a parsable JSON format.

CSV Database
In addition to our MaxMind DB binary format, we also offer GeoIP2 and GeoLite2 databases in a CSV format suitable for importing into a SQL database. The CSV files are shipped as a single zip file.The zip file itself is named GeoIP2-Connection-Type-CSV_{YYYYMMDD}.zip.
The downloaded zip file contains a single directory which in turn
contains several files. That directory is named
GeoIP2-Connection-Type-CSV_{YYYYMMDD}.
The files in this zip archive are:
| Filename | Description |
|---|---|
LICENSE.txt | End user license |
COPYRIGHT.txt | Copyright statement |
GeoIP2-Connection-Type-Blocks-IPv4.csv | CSV file containing data on IPv4 addresses |
GeoIP2-Connection-Type-Blocks-IPv6.csv | CSV file containing data on IPv6 addresses |
Blocks Files
There are two CSV files for network blocks, one each for IPv4 and IPv6 blocks.
These are named GeoIP2-Connection-Type-Blocks-IPv4.csv and
GeoIP2-Connection-Type-Blocks-IPv6.csv respectively.
| Name | Type | Description |
|---|---|---|
| network | IP network as a string | This is the IPv4 or IPv6 network in CIDR format such as “2.21.92.0/29” or “2001:4b0::/80”. We offer a utility to convert this column to start/end IPs or start/end integers. See the conversion utility section for details. |
| connection_type | string | One of the following values: Cable/DSL, Cellular, Corporate, or
Satellite. Additional values may be added in the future.Learn more about connection type data on our Knowledge Base. |
Conversion Utility
We’ve created a small utility program to allow you to convert a GeoIP2 CSV file’s representation of IP addresses to another format. You can choose between start/end IP addresses, with the addresses represented as strings or integers.
The program is available from our geoip2-csv-converter GitHub project releases tab.
Example Files
We maintain example files in CSV and MMDB format. The files contain dummy data rather than real GeoIP data.CSV Example Files
We maintain examples of the CSV files as they would be downloaded from the account portal:
MMDB Example Files
We maintain test MMDB files on GitHub:
Alternatively, you can view all of our MMDB test data on GitHub.
Database Sizes
MaxMind databases can vary in size from release to release. If you are working with file size limitations that are concerning, you should build your integrations to fail gracefully in event of a significant size change.
From August to October 2024, the database files varied in file size and number of networks as follows:
| Database | CSV File Size | MMDB File Size | IPv4 Networks | IPv6 Networks |
|---|---|---|---|---|
| GeoIP Connection Type | 31.96 MB - 34.37 MB | 9.31 MB - 9.84 MB | 971,000 - 1,076,000 | 210,000 - 225,000 |
The listed file sizes are for unpacked databases. Databases are downloaded in a compressed format.
Database Changes
We may add new data fields to the Connection Type database at any time.
New database fields are added as new columns to the right of existing columns in our CSV files, and as additional data in our MMDB files.
Subscribe to our GeoIP2 release notes to be notified when new data is added to our databases.
