The Digital Distributed Name Service (DECdns) is a network-
    wide service that makes it possible to use network resources
    without having to know their physical location.

    The DNS Clerk is the module of the DNA Naming Service that
    interfaces directly with client applications. A clerk module is
    required on every DECnet-Plus node whether or not that node also
    functions as a DECdns nameserver. The clerk is created during
    configuration of the network software.

    You can manage the DNS server and DNS clerk modules from either NCL
    or the DECdns control program (DNSCP). The commands are the same for
    both interfaces and are documented in the DECdns Management manual.
    On-line help for DECdns is available from DNSCP only.
