Determine geolocation data such as country, region, state, city, ZIP/postal code, and additional intelligence such as confidence factors, ISP, domain, and connection type. To learn more about the GeoIP Enterprise database, please visit the [GeoIP Enterprise Database page](https://www.maxmind.com/en/geoip-enterprise-database). If you are interested in purchasing the database, please [contact our Enterprise Business team](https://www.maxmind.com/en/solutions/connect-with-a-geoip-expert) for assistance. **IP Geolocation Usage** IP geolocation is inherently imprecise. Locations are often near the center of the population. Any location provided by a GeoIP database should not be used to identify a particular address or household. **Data Privacy** To comply with data privacy regulations, please monitor our [Do Not Sell My Personal Information Requests](https://www.maxmind.com/en/accounts/current/do-not-sell-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](/geoip/privacy-exclusions-api). ## Binary Database Binary databases make use of the [MaxMind DB file format](https://maxmind.github.io/MaxMind-DB/). MaxMind provides [official client APIs](/geoip/docs/databases/#official-client-apis) that are open source. We also provide a list of [unsupported and unofficial client APIs](/geoip/docs/databases/#unofficial-client-apis) and [unsupported and unofficial integrations](/geoip/docs/databases/#integrations) with various applications. You can also use the [mmdbinspect tool](https://github.com/maxmind/mmdbinspect) (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. [Learn about the fields in the binary version of this database on our binary database field reference page.](binary/) ## CSV Database In addition to our MaxMind DB binary format, we also offer GeoIP and GeoLite 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-Enterprise-CSV_{YYYYMMDD}.zip`. The downloaded zip file contains a single directory which in turn contains several files. That directory is named `GeoIP2-Enterprise-CSV_{YYYYMMDD}`. The files in the zip archive are:
Filename Description
COPYRIGHT.txt Copyright statement
LICENSE.txt End user license
GeoIP2-Enterprise-Blocks-IPv4.csv CSV file containing data on IPv4 addresses
GeoIP2-Enterprise-Blocks-IPv6.csv CSV file containing data on IPv6 addresses
GeoIP2-Enterprise-ISP.csv CSV file containing data on ISPs. This may be cross referenced with the various blocks files using the shared isp_id key.
GeoIP2-Enterprise-Locations-{locale}.csv CSV files containing data on locations. This may be cross referenced with the various blocks files using the shared geoname_id key.
All the CSV files start with a single header row containing column names. The specific column names and their contents are detailed below. The files are encoded as UTF-8. ### Blocks Files There are two CSV files for network blocks, one each for IPv4 and IPv6 blocks. These files are named `GeoIP2-Enterprise-Blocks-IPv4.csv` and `GeoIP2-Enterprise-Blocks-IPv6.csv` respectively. | Data field name | Type | Data field 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::/64".

Files corresponding to other locales will exist and have a record for a `geoname_id` only if data is available. The other possible locales are "de", "es", "fr", "ja", "pt-BR", "ru", and "zh-CN". These files are named `GeoIP2-Enterprise-Locations-{locale}.csv`. An example name would be `GeoIP2-Enterprise-Locations-en.csv`. | Data field name | Type | Data field description | |------|------|-------------|| | geoname_id | integer | A unique identifier for the location as specified by [GeoNames](https://www.geonames.org/).

It is `0` otherwise. | | ### Returned Values as Database, Map, Dict, or Hash Keys **We strongly discourage you from using a value from any `*_name` field as a key in a database or map/dict/hash data structure.** These names may change between releases. Instead we recommend using one of the following: | Data object | Recommended key | | ------------ | ---------------------------- | | city | `geoname_id` | | continent | `continent_code` | | country | `country_iso_code` | | postal | `postal_code` | | subdivisions | `subdivision_{1,2}_iso_code` | ### Conversion Utility We've created a [small utility program](https://github.com/maxmind/geoip2-csv-converter) to allow you to convert a GeoIP 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.](https://github.com/maxmind/geoip2-csv-converter/releases) ## 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: - [GeoIP2-Enterprise-CSV_Example.zip](/examples/GeoIP2-Enterprise-CSV_Example.zip) ### MMDB Example Files We maintain test MMDB files on GitHub: - [GeoIP2-Enterprise-Test.mmdb](https://github.com/maxmind/MaxMind-DB/blob/main/test-data/GeoIP2-Enterprise-Test.mmdb) Alternatively, you can [view all of our MMDB test data on GitHub](https://github.com/maxmind/MaxMind-DB/tree/main/test-data). ## Database Changes We may add new data fields to the Enterprise 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 [GeoIP release notes](/geoip/release-notes) to be notified when new data is added to our databases. ## 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 May to August 2026, the database files varied in file size and number of networks as follows: | Database | CSV File Size | MMDB File Size | IPv4 Networks | IPv6 Networks | |----------|---------------|----------------|---------------|---------------| - databaseName: "GeoIP Enterprise" csvSizeRange: "1.12 GB - 1.27 GB" mmdbSizeRange: "339 MB - 401 MB" ipv4Range: "7,877,000 - 9,470,000" ipv6Range: "4,699,000 - 4,888,000" The listed file sizes are for unpacked databases. Databases are downloaded in a compressed format. ## APIs and Third-Party Integrations You can find a complete list of official and unofficial client APIs, and third-party integrations on the [database documentation page](/geoip/docs/databases#client-apis). ## [GeoIP Enterprise binary database fields](/geoip/docs/databases/enterprise/binary/)

The GeoIP Enterprise binary database contains the following fields for each network. The top-level record for each network is a map containing the keys listed below. Each key maps to a map or an array of maps. If a key maps to an undefined or empty value, it is not included in the record.
