NETWORKS(5)                   File Formats Manual                  NETWORKS(5)



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
       getnetent(3N)

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