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 charac‐
       ter  (#) 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
              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 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 file.

FILES
       /etc/networks
              The networks definition file.
