 105 integrates with the DNS server and allows machines with DHCP-allocated

 374     (description "@dfn{NSD}, short for Name Server Daemon, is an authoritative
 375 name server for the Domain Name System (@dfn{DNS}).  It aims to be a fast and
 376 RFC-compliant nameserver.
 377
 378 NSD uses zone information compiled via @command{zonec} into a binary database
 379 file (@file{nsd.db}).  This allows fast startup of the name service daemon and
 380 allows syntax-structural errors in zone files to be flagged at compile time,
 381 before being made available to NSD service itself.  However, most traditional
 382 BIND-style zone files can be directly imported into NSD without modification.
 383
 384 The collection of programs and processes that make up NSD are designed so that
 385 the daemon itself runs as a non-privileged user and can be easily configured to
 386 run in a @code{chroot} jail, thus making any security flaws in NSD less likely
 387 to result in system-wide compromise.")
