NETWORKS(4)                                           NETWORKS(4)



     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

     SEE ALSO

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