A C library for reading MaxMind DB files, the binary format used by MaxMind's GeoIP databases. It provides fast IP address lookups with flexible associated data types via a simple C API.
Use cases
- look up geolocation data for an IP address in C
- read GeoIP2 mmdb database files
- resolve IP to country/city in a server application
- parse MaxMind DB binary format
- embed IP geolocation lookups in a native application
When to choose
- you need fast, low-level IP-to-GeoIP lookups in C or C++
- you want a lightweight dependency with no runtime requirements
- you need cross-platform support including Windows via CMake
When to avoid
- you want a high-level language binding (use official Python/Java/Go clients instead)
- you need to write MaxMind DB files rather than read them
- you need live IP intelligence updates rather than local database reads
