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 main-
       tained 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.
