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

 586
 587 NSD uses zone information compiled via @command{zonec} into a binary database
 588 file (@file{nsd.db}).  This allows fast startup of the name service daemon and
 589 allows syntax-structural errors in zone files to be flagged at compile time,
 590 before being made available to NSD service itself.  However, most traditional
 591 BIND-style zone files can be directly imported into NSD without modification.
 592
 593 The collection of programs and processes that make up NSD are designed so that
 594 the daemon itself runs as a non-privileged user and can be easily configured to
 595 run in a @code{chroot} jail, thus making any security flaws in NSD less likely

1014 addresses with several dynamic DNS service providers, such as
1015 @uref{https://www.dyndns.com/account/login.html,DynDNS.com}.
1016
1017 This makes it possible to use a fixed hostname (such as myhost.dyndns.org) to
1018 access a machine with a dynamic IP address.
1019
1020 The client supports both dynamic and (near) static services, as well as MX
1021 record and alternative name management.  It caches the address, and only
1022 attempts the update when it has changed.")
