NAME
     networks - network name data base

DESCRIPTION
     The networks file contains information regarding  the  known
     networks  which  comprise the DARPA Internet.  For each net-
     work 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  char-
     acters.  A `#' indicates the beginning of a comment; charac-
     ters up to the end of the line are not interpreted  by  rou-
     tines  which search the file.  This file is normally created
     from the official network data base maintained at  the  Net-
     work  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 delim-
     iter, NEWLINE, or comment character.

FILES
     /etc/networks

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