     NAME
          networks - network name information

     DESCRIPTION
          The file /etc/networks is a plain ASCII file that describes
          known DARPA networks and symbolic names for these networks.
          Each line represents a network and has the following struc-
          ture:

               name number aliases ...

          where the fields are delimited by spaces or tabs.  Empty
          lines are ignored.  The hash character (#) indicates the
          start of a comment: this character, and the remaining char-
          acters up to the end of the current line, are ignored by
          library functions that process the file.

          The field descriptions are:

          name The symbolic name for the network.  Network names can
               contain any printable characters except white-space
               characters or the comment character.

          number
               The official number for this network in numbers-and-
               dots notation (see inet(3)).  The trailing ".0" (for
               the host component of the network address) may be omit-
               ted.

          aliases
               Optional aliases for the network.

          This file is read by the route(8) and netstat(8) utilities.
          Only Class A, B or C networks are supported, partitioned
          networks (i.e., network/26 or network/28) are not supported
          by this file.

     FILES
          /etc/networks
               The networks definition file.
