The Geofeed dataset aggregates the location data that network operators publish themselves in RFC 8805 geofeeds. Ipregistry continuously crawls, validates and consolidates these feeds into a single normalized file.
Because the data comes straight from the networks that run the address space, it is a high-trust signal for correcting and refining IP geolocation, especially for recently moved or newly allocated ranges.
Available formats
| Format | Description | Size |
|---|---|---|
| CSV | Plain text, one range per line. Import into any database or data warehouse. | 7.8 GB |
| CSV (zipped) | Same file compressed for faster downloads and cheaper storage. | 651 MB |
| MMDB | Binary format for instant lookups with standard MMDB readers. | 1.1 GB |
Latest build: 138,078,883 records. Files are regenerated every day and published with MD5, SHA-1, SHA-256 and SHA-512 checksums so you can verify every download.
What's inside
The CSV file starts with a header line and contains one record per row, with the following fields:
| Column | Description |
|---|---|
city | City declared by the operator. |
country_code | ISO 3166-1 alpha-2 country code declared by the operator. |
postal | Postal code declared by the operator. |
region_code | ISO 3166-2 region code declared by the operator. |
subnet | IP prefix the entry applies to, in CIDR notation. |
The MMDB variant carries the same data in a memory-mapped binary tree, compatible with the standard MMDB reader libraries available for every major programming language.
What you can build
- Cross-check and correct third-party geolocation with operator-declared locations
- Track how networks relocate address space over time
- Bootstrap geolocation for research without crawling thousands of geofeeds yourself
- Audit your own published geofeed against what crawlers actually see
