v3.18.0 · 1mo ago
Offline IP-to-region lookup library and data management framework supporting IPv4 and IPv6 with xdb query clients.
Why you might care
Resolves IPs to country, province, city, ISP and ISO code locally with no network calls, at roughly 10-microsecond query time when the xdb file is cached in memory. Ships ready-made IPv4 and IPv6 data and lets you append custom fields like GPS or zip codes to build your own IP location database.
