ip2region is an offline IP geolocation library and data-management framework supporting both IPv4 and IPv6. It ships with raw IP datasets and optimized XDB database files for city-level region lookup. Returned records can include country, province, city, ISP, and ISO country-code information. The XDB format supports large datasets, deduplication, compression, and customizable region fields. Query implementations are available for many languages, including Go, Java, Python, PHP, Rust, C, C++, JavaScript, C#, Lua, Erlang, and others. Several cache strategies allow applications to trade memory use for faster query performance, with fully cached lookups operating at microsecond-level speeds. ...

...It is primarily a reference collection rather than a single hosted API implementation. The list includes services for detecting a visitor's public IP, looking up a supplied IP address, retrieving geolocation data, and obtaining ISP or network details. Entries are grouped by capabilities such as self-IP lookup, arbitrary IP lookup, reverse regional queries, and simple IP-only responses. The documentation records request methods, parameters, CORS behavior, example responses, and whether individual services have stopped working. Many endpoints use simple GET requests and return JSON or similarly lightweight responses. ...
