Country IP Blocks
Hourly-updated CIDR country-level IP data sourced directly from Regional Internet Registries.
What is Country IP Blocks?
Country IP Blocks is a repository providing CIDR (Classless Inter-Domain Routing) data that maps IP address ranges to specific countries. It sources this information directly from Regional Internet Registries and updates it hourly to ensure accuracy. The project serves as a read-only mirror of this geolocation data for easy access and integration.
Network administrators, security professionals, and developers who need accurate country-level IP geolocation data for firewall rules, content regionalization, or network analysis.
Developers choose Country IP Blocks because it provides directly-sourced, frequently updated IP geolocation data from authoritative RIRs, eliminating the need to scrape or parse multiple sources manually.
Overview
CIDR country-level IP data, straight from the Regional Internet Registries, updated hourly. This is a read-only mirror.
Use Cases
Best For
- Implementing country-based IP filtering in firewall configurations
- Geolocating website visitors for content regionalization
- Analyzing network traffic by country of origin
- Building IP reputation systems with country-level data
- Creating network security rules based on geographic locations
- Developing applications that require accurate IP-to-country mapping
Not Ideal For
- Applications needing sub-country granularity like city or ISP-level geolocation
- Projects requiring a hosted API for dynamic, on-demand IP lookups
- Teams wanting to contribute to or fork the dataset directly via GitHub pull requests
Pros & Cons
Pros
Sources directly from Regional Internet Registries, ensuring high accuracy and reliability, as stated in the project description.
Data is refreshed every hour from official RIR sources, providing current geolocation information for time-sensitive applications.
Provides data in CIDR notation, making it easy to integrate into network configurations and scripts, as highlighted in the key features.
Serves as a read-only mirror, offering straightforward access to raw data files without complex setup or dependencies.
Cons
Only maps IP ranges to countries, lacking city or region details, which may not suffice for applications needing finer location data.
Requires manual parsing of static data files, as there's no provided API for on-demand queries, increasing integration effort.
The README indicates the repository has moved to a personal website, which may lead to broken links or reduced community support on GitHub.
