networks(4N)                     (TCP/IP)                      networks(4N)


   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

   SEE ALSO
         getnetent(3N), inet(7).

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