It loads Maxmind GeoLite2 data into memory and performs lookups via binary search on ordered IP ranges, returning country codes, city names, ASN names, and CIDR blocks for both IPv4 and IPv6 addresses. The library requires no external dependencies or network calls\u2014only the Python file and a .dat.gz data file.\n\nThe package ships with a small country-level IPv4 database, but city and IPv6 variants must be downloaded separately or generated from Maxmind CSV files using the included geoip2dat.py tool. Data files are updated twice weekly. The library supports Python 3.7 through 3.13 and PyPy3, runs on Linux, Windows, and macOS, and is designed for applications that need fast, offline geolocation without external service dependencies.","worth_installing":"Yes, with conditions. Install if you need fast, offline IP geolocation and are willing to manage data file downloads separately. The library is actively maintained, has no dependencies, and supports current Python versions. High install friction (separate data file requirement) and the need to choose between country/city and IPv4/IPv6 variants make it less suitable for quick prototyping, but it is well-suited for production systems where speed and offline operation matter."},"id":"geoip2fast","links":{"html":"https://skillfed.io/packages/geoip2fast","md":"https://skillfed.io/packages/geoip2fast.md","pypi":"https://pypi.org/project/geoip2fast/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2024-06-21","license_spdx":null,"license_treatment":"permissive","name":"geoip2fast","python_support":"supports_current","summary":"GeoIP2Fast is the fastest GeoIP2 country/city/asn lookup library that supports IPv4 and IPv6.
