The NLnet Labs Name Server Daemon (NSD) is an RFC compliant authoritative DNS nameserver. It was ﬁrst conceived to allow for more diversity for DNS server implementations used by the root-server system. It has been developed for operations in environments where speed, reliability, stability, and security are of high importance. NSD is currently used on root servers such as k.root-servers.net and is also in use by several top-level domain registries.
