The decnet_register tool is the primary method used by the
    namespace administrator to manage the node objects contained
    in both the DECdns distributed name service (DECdns) and the
    Local namespace. The DECdns control program, dnscp, can also
    be used to manage the DECdns namespace and its contents.

    Refer to HELP NETWORK_MANAGEMENT TOOLS DECNET_REGISTER.
    Or see the DECnet-Plus Network Management book for information
    about decnet_register and for instructions on registering,
    deregistering, modifying, and renaming node names.
    See the DECdns Management guide for information about
    dnscp and for detailed instructions on managing the namespace
    and its contents.
