NAME
      networks - network name data base

DESCRIPTION
      The networks file contains information regarding the known networks which
      comprise the DARPA Internet.  For each network a single line should be
      present with the following information:

            official-network-name   network-number    aliases

      Items are separated by any number of SPACE and/or TAB characters.  A `#'
      indicates the beginning of a comment; characters up to the end of the
      line are not interpreted by routines which search the file.  This file is
      normally created from the official network data base maintained at the
      Network Information Control Center (NIC), though local changes may be
      required to bring it up to date regarding unofficial aliases and/or
      unknown networks.

      Network number may be specified in the conventional `.'  notation using
      the inetnetwork routine from the Internet address manipulation library,
      inet(7).  Network names may contain any printable character other than a
      field delimiter, NEWLINE, or comment character.

FILES
      /etc/networks

NOTES
      A name server should be used instead of a static file.  A binary indexed
      file format should be available for fast access.
