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 structure:

              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 characters 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  execept  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 omitted.

       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,  par-
       titioned networks (i.e., network/26 or network/28) are not supported by this facility.

FILES
       /etc/networks
              The networks definition file.
