/DOMAIN=domain.name

    Required.

    Domain for which to extract data. Determines whether to perform
    forward translation or reverse translation. The following
    restrictions and instructions apply:

    o  The domain name must be fully qualified.

    o  The closing dot is not required.

    o  Do not use wildcards.

    o  Specify up to four parts of the IP address for varying degrees
       of selectivity. For example:

       /DOMAIN=16.IN-ADDR.arpa is less selective.

       /DOMAIN=8.20.16.IN-ADDR.arpa is more selective.

    The end of domain.name determines whether a forward or reverse
    translation is performed. For example:

    o  If the domain name ends in IN-ADDR.arpa:

       -  Reverse translation is performed.

       -  The domain is some part of an IP address, reversed, and
          added to IN-ADDR.arpa.

       -  The selection includes the contents of the hosts database
          in the output.

    o  If the domain name ends in anything else (for example,
       /DOMAIN=DAW.MAG.COM):

       -  Forward translation is performed.

       -  All hosts in domain.name or in any of its subdomains are
          selected for the output file.

       -  CONVERT/UNIX BIND does a forward translation and selects
          hosts in DAW.MAG.COM and in its subdomains.
