    From the README

    ip2region - is an offline IP address localization library and IP localization data management framework. It supports both IPv4 and IPv6 with query efficiency at the 10-microsecond level. It provides xdb data generation and query client implementations for many mainstream programming languages.

    The project itself provides raw data for both IPv4 (data/ipv4_source.txt) and IPv6 (data/ipv6_source.txt), along with corresponding xdb files (data/ip2region_v4.xdb and data/ip2region_v6.xdb) to achieve city-level query localization. The field format is: Country|Province|City|ISP|iso-alpha2-code. Localization information for China is entirely in Chinese, while regional information for non-China areas is entirely in English.
