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  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 facility.
