Creating a geofeed is valuable for organizations and network operators to improve the accuracy, transparency, and usability of geolocation data tied to IP addresses.

Please submit your geofeed to us, so that we can provide custom data to our audiences.

The geofeed format is a standardized text-based format used to associate geolocation information (latitude, longitude, and region data) with IP address prefixes. It is commonly used in internet routing and geolocation services to enable accurate and precise mapping of IP addresses to geographic locations.

Key Features of Geofeed Format

1. File Format:

• The geofeed file is a plain-text, CSV (Comma-Separated Values) formatted document.
• Each line represents a record that associates an IP address prefix with geographic data.

2. Fields in a Geofeed Record:

Each line of the geofeed file typically includes the following fields:

• IP Prefix: Specifies the IPv4 or IPv6 prefix.
• ISO 3166-1 Alpha-2 Country Code: A two-letter country code indicating the country.
• ISO 3166-2 Subdivision Code: An optional field indicating a state, province, or region within the country.
• City Name: An optional field specifying the city associated with the prefix.
• Latitude and Longitude: Optional fields providing precise geographic coordinates.

Example:

Example of a geofeed record:

192.0.2.0/24,US,CA,San Francisco,37.7749,-122.4194
2001:db8::/32,DE,,,,

3. Purpose:

• Geolocation Services: Used by providers to give accurate location data to geolocation databases.
• Network Operators: Helps in defining where IP address blocks are geographically located.
• Routing and Policy: Can be used by entities to apply policies based on geographic location.

4. Compliance and Transparency:

• The geofeed format is openly available and is often linked in WHOIS records.
• It enables transparency for organizations managing IP address space by openly declaring the geographic mappings.
