GeoIP
This project automatically generates GeoIP files in multiple formats
...Rather than depending solely on the official GeoLite2 data, geoip augments and merges data sources (especially for certain regions) to improve coverage or tailor by use-case (e.g. proxy-specific rules, private networks, or region-based classification). The repo provides automated, periodic releases (e.g. weekly or on schedule) and also offers a CLI tool so users can regenerate or customize geo data in the format they need — for example, producing a .dat file for V2Ray / Xray-core, or a MaxMind-compatible .mmdb.
