## What it is
A compact (~100 KB) GeoIP2 database containing only mainland China IP address ranges, built by merging ipip.net and CZ (纯真) data and updated automatically every three days. It is designed as a drop-in replacement for MaxMind GeoLite2 in proxy tools like Surge, Clash, Shadowrocket, and Quantumult X for accurate GEOIP,CN routing decisions.

## Use cases
- make GEOIP,CN rules direct China traffic accurately in Clash or Surge
- replace GeoLite2 mmdb that requires registration to download
- reduce proxy tool memory and load time with a tiny China-only IP database
- fix wrong geo-lookup of Chinese IPs like Alibaba Cloud Hong Kong
- download a CN ip-cidr list for firewalls or older proxy tools
- auto-update China IP data every few days via CDN

## When to choose
- your proxy rules only need to distinguish mainland China IPs from everything else
- you use Surge, Clash, Shadowrocket, Quantumult X, or similar tools and want accurate, fast GEOIP,CN lookups
- you want a small, frequently updated, CDN-distributed database without MaxMind registration

## When to avoid
- you need GeoIP lookups for countries or regions other than mainland China
- you need detailed ISP, city, or ASN metadata for IPs
- you need a general-purpose global geolocation database

## Facets
- artifact type: dataset
- maturity: active
- function: search-engine, networking, security
- domain: networking, privacy, censorship-circumvention, developer-tools
- platform: cross-platform, self-hosted
- tags: geoip, geoip2, mmdb, china-ip, proxy-rules, surge, clash, shadowrocket, quantumultx, ip-database
