## プロジェクトの歴史と使われ方

ChinaDNS-C is the packaged C implementation of ChinaDNS, a small DNS forwarder built for networks affected by DNS poisoning and CDN split-horizon behavior.

### プロジェクトの歴史

The upstream repository started in 2014 and its README describes a DNS design that queries local resolvers for Chinese domains and foreign resolvers for foreign domains, using a relatively stable Chinese IP range file instead of fast-changing domain lists. The project is closely tied to the Shadowsocks-era anti-censorship tooling ecosystem and explicitly points users toward VPN software such as ShadowVPN for IP blocking.

### 採用の歴史

Upstream documented Linux/Unix builds, OpenWrt packaging, Tomato-router cross-compilation, and a Windows Python executable, which made the tool relevant beyond a single desktop formula. Homebrew packages the C port as chinadns-c and tracks the 1.3.2 release tarball.

### 使われ方

Typical use is running chinadns as a local UDP DNS server, often with dnsmasq on routers, with a chnroute.txt file generated from APNIC delegated address data and options such as DNS compression pointer mutation.

### パッケージ好きにとっての重要性

For package people, chinadns-c is a compact example of network-circumvention software moving from router firmware workflows into general-purpose package managers, with Homebrew preserving a once-active C utility from the Shadowsocks orbit.

### タイムライン

- 2014: First commits in the official ChinaDNS repository.
- 2014: 1.0.0 tag appears shortly after the initial import.
- 2015: README copyright and later 1.3.x tags show the mature C release line packaged by Homebrew.
- 2026: Homebrew still exposes chinadns-c as a bottled formula at stable version 1.3.2.

### Related projects

- The README names ShadowVPN as companion VPN software and dnsmasq as the recommended local DNS front end on OpenWrt. chnroute.txt generation is based on APNIC delegated address data.
