NAME
       networks - network name data base

DESCRIPTION
       The file associates Internet (IP) addresses with official network names
       and aliases.  This allows the user to refer to a network by a  symbolic
       name  instead of using an Internet address.  For each network, a single
       line should be present with the following information:

	      <official network name>	<network number>   <aliases>

       Aliases are other names under which a network is known.	For example:

       where the network named is also called

       A line cannot start with a blank (tab or space character).   Items  are
       separated  by  any  number or combination of blanks.  A character indi‐
       cates the beginning of a comment.  Characters from the up to the end of
       the line are not interpreted by routines which search the file.	Trail‐
       ing blanks are allowed at the end of a line.  For  the  Internet,  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 numbers can be specified in conventional Internet dot  notation
       using  the  routine from the internet address manipulation library (see
       inet(3N).  Network names can contain any printable character other than
       a white space, new-line, or comment character.
