The Geolocation dataset maps the entire routable IPv4 and IPv6 address space to physical locations. Every range resolves to a country, and most ranges resolve further to a region, city, postal code, latitude and longitude, and time zone.
It is the same data that powers the Ipregistry API, built from authoritative registry data, operator-published geofeeds, network measurements and continuous quality checks, then packaged for offline use in your own infrastructure.

Use cases
What you can build
- Localize content, currencies and languages without calling an external API on each request
- Enrich analytics events, logs and data warehouses with location at ingestion time
- Apply geo-based access rules and compliance restrictions in latency-sensitive paths
- Batch process historical traffic where per-request API lookups are impractical
