country-ip-blocks (formerly rir-ip)

📢 Heads up: This repo has a new name and the data format has changed. Check out MIGRATION.md for what you need to update.

Ready-to-use IPv4 and IPv6 prefixes delegated to countries (ISO 3166-1 alpha-2), sourced from all five regional internet registries (RIR).

This dataset saves you from parsing RIR delegation files yourself - the prefixes are aggregated and ready to drop into firewalls, access control lists, or geo-routing configurations. Updated daily when the underlying RIR data changes, so you always have current allocations.

Note: This data shows which country an IP range is delegated to by the RIRs. While it can be used for country-level blocking and compliance, it has limitations - delegated IPs can be used in other countries or routed globally. For pinpoint geolocation (city-level, actual user location), you'll need a dedicated geolocation service.

Recent changes

• 2026-01-03: Repo renamed from rir-ip to country-ip-blocks and JSON format updated to use camelCase. Check MIGRATION.md if you're already using this data.
• 2025-05-04: Removed country code EU (non-standard code that RIPE only kept for historical reasons)

Want more granular control?

Instead of blocking an entire geographic region, it might be more effective to block specific internet providers based on their autonomous system number (ASN). Check out as-ip-blocks for more information.

Use cases

• Block entire countries at the firewall (for compliance or security reasons)
• Geo-based access control and traffic routing
• Network research and statistical analysis
• Threat hunting and security research
• Figure out which IPs are delegated to specific countries
• Pretty much anything where you need to map country codes to their delegated networks
