NAME

       networks - network name information

DESCRIPTION

       The  file  /etc/networks is a plain ASCII file that describes known DARPA networks and symbolic names for these networks.  Each line repre-
       sents a network and has the following structure:

	      name number aliases ...

       where the fields are delimited by spaces or tabs.  Empty lines are ignored.  The hash character (#) indicates the start of a comment:  this
       character, and the remaining characters up to the end of the current line, are ignored by library functions that process the file.

       The field descriptions are:

       name   The  symbolic name for the network.  Network names can contain any printable characters except white-space characters or the comment
	      character.

       number The official number for this network in numbers-and-dots notation (see inet(3)).	The trailing ".0" (for the host component  of  the
	      network address) may be omitted.

       aliases
	      Optional aliases for the network.

       This  file is read by the route(8) and netstat(8) utilities.  Only Class A, B or C networks are supported, partitioned networks (i.e., net-
       work/26 or network/28) are not supported by this facility.

FILES

       /etc/networks
	      The networks definition file.
