Knot Resolver

Full caching DNS resolver with DNSSEC, DNS over TLS and HTTPS, and a YAML-configured manager

Desktopfree

Knot Resolver is an open-source caching DNS resolver that answers and caches DNS queries for a network. It validates DNSSEC, supports encrypted DNS over TLS and HTTPS, scales by replicating worker processes across CPU cores without downtime, and is configured through YAML with an HTTP API for live changes. It is used by network operators running their own resolver and by researchers working with DNS data.
