	thats easy...   the number of allocated IPv4 /32s and the 
	number of allocated IPv6 /64s.  By definition, private
	networks (RFC 1918) space is not part of the Internet.

	Or, is your question actually the absolute number of globally
	reachable IP addresses at any given instant?  (reachable from where?)

	Or do you mean anything that might have an IP address associated with 
	it at some time in its existance?

	Clarity would be helpful if you want a repeatable answer.
