     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 blanks 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 inet_network() routine from the Internet
          address manipulation library, inet(3N).  Network names may
          contain any printable character other than a field
          delimiter, 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.
