GeoForge compiles a local IPv4 GeoIP database from multiple free or low-cost data sources. The builder uses DB-IP Lite as the prefix seed, merges location candidates from MaxMind GeoLite2, IP2Location LITE, Sypex Geo, and allowlisted operator geofeeds, then enriches the result with GeoNames postal and city reference data.
