networks(4N)                                         networks(4N)



NAME
     networks - network name database

DESCRIPTION
     The networks file contains information regarding  the  known
     networks  of  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  that  search  the  file.   This  file  is normally
     created from the official network database 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.

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

FILES
     /etc/networks
