## What it is
SmartDNS is a local DNS server written in C that queries multiple upstream DNS servers concurrently and returns the fastest-responding IP to clients, improving network access speed. It supports DoT, DoH, and DoQ for encrypted queries, per-client rules, domain-based routing, and ad filtering, and runs on Linux, OpenWrt, ASUS routers, Raspberry Pi, and Windows/WSL.

## Use cases
- speed up website access by resolving the fastest IP
- run a local DNS server with DNS over HTTPS/TLS/QUIC
- block ads and malicious domains via DNS
- split DNS queries across different upstream servers per domain
- set up DNS on an OpenWrt or ASUS router
- apply parental controls per client device by MAC or IP

## When to choose
- you want faster browsing by picking the fastest IP from multiple upstream DNS servers
- you need encrypted DNS (DoT/DoH/DoQ) on a router or local network
- you want DNS-level ad filtering with high-performance domain matching
- you need per-client DNS rules or domain-based upstream routing with nftables/ipset integration

## When to avoid
- you need a full recursive authoritative DNS server rather than a forwarding/caching resolver
- you want a GUI-first DNS solution with minimal configuration
- your platform is unsupported (e.g., non-Linux embedded systems outside OpenWrt/ASUS)
