## What it is
ChinaDNS-NG is a rewritten and enhanced version of ChinaDNS that splits DNS queries between domestic (China) and trusted upstream DNS servers based on domain lists like chnlist and gfwlist. It supports UDP/TCP/DoT upstreams, dynamic ipset/nftset population, DNS caching, and fine-grained IPv6 filtering to support transparent proxy and anti-censorship routing setups.

## Use cases
- split DNS queries between Chinese and foreign DNS servers
- avoid DNS poisoning when resolving blocked domains
- populate ipset or nftables sets with resolved IPs for transparent proxying
- prevent DNS leaks when using a VPN or proxy
- run a lightweight DNS forwarder on an OpenWrt router
- resolve Chinese domains via domestic DNS for CDN-friendly results

## When to choose
- you need DNS-based traffic splitting for transparent proxy setups like ss-tproxy
- you want gfwlist/chnlist-based domain routing with ipset/nftset integration
- you run a Linux router or embedded device and need a fast, low-memory DNS splitter
- you need DoT support and DNS caching with stale-cache and pre-refresh features

## When to avoid
- you need a general-purpose full-featured DNS server like dnsmasq or AdGuard Home
- you are not in a censorship/DNS-pollution scenario and just need a simple DNS resolver
- you need DNS-over-HTTPS upstreams, which are not supported
- you need a GUI-managed DNS solution
