About:
ChinaDNS-C is a lightweight DNS server implementation designed to resolve irregularities in the Great Firewall of China. It intelligently filters and returns correct IP addresses for domains that are typically poisoned or hijacked by local DNS resolvers. This tool ensures reliable and fast internet access by bypassing DNS-based censorship.

Key Features:

Filters poisoned DNS responses to provide correct IP addresses
Lightweight C implementation for high performance and low resource usage
Simple configuration and easy deployment
Works as a local DNS resolver or forwarder

Use Cases:

Bypassing DNS censorship in restrictive network environments
Improving internet connectivity reliability for users in China
Setting up a local DNS server to handle polluted domains

Alternatives:

dnscrypt-proxy – Encrypts DNS traffic and bypasses censorship, but ChinaDNS-C is specifically optimized for the unique DNS poisoning patterns in China.
unbound – A general-purpose recursive DNS resolver with DNSSEC support, whereas ChinaDNS-C focuses specifically on circumventing GFW DNS interference.
