What about a tri-state variable:

	In-Use		--	Confirmed valid contact information within the last year
					Contact verifies that addresses are still in active use.
	Abandoned	--	Unable to reach contact.  Good faith efforts to contact
					organization and contacts have failed. in-addr delegation
					is lame/broken, not visible in routing table.
	Unknown	--	Similar to Abandoned, but, efforts to reach the org. and/or
					its contacts have not been completed yet.
