NSD

In Internet computing, NSD is an open-source server program for the Domain Name System. The intention of this development is to add variance to the "gene pool" of DNS implementations used by higher level name servers and thus increase the resilience of DNS against software flaws or exploits. The collection of programs/processes that make-up NSD are designed so that the NSD daemon itself runs as a non-privileged user and can be easily configured to run in a Chroot jail, such that security flaws in the NSD daemon are not so likely to result in system-wide compromise as without such measures.
