Knot DNS is a high-performance open-source DNS server. It implements only the authoritative domain name service. Knot DNS can reliably serve TLD domains as well as any other zones.
Knot DNS benefits from its multi-threaded and mostly lock-free implementation which allows it to scale well on SMP systems and operate non-stop even when adding or removing zones.
The server itself is accompanied by several utilities for general DNS operations or for maintaing the server.
