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 charac-
              ters 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,  partitioned
       networks (i.e., network/26 or network/28) are not supported by this facility.

FILES
       /etc/networks
              The networks definition file.
