	    the last 3 months.

      7328 registered and never announced

		the IRR but have not been announced in the last three

		route objects is very easy.

      44595 never announced but aggregated
		This is the list of prefixes that are registered in
		the IRR but have not been announced in the last three
		months but are likely to still be reachable since and
		aggregate is announced. The route objects can be
		deleted, marked as withdrawn, or using RPSL, the
		aggregate can be marked to limit the scope of the more
		specific routes.

	There were 44595 prefixes that are registered in the IRR but
	have not been announced and recorded in the route dumps taken
	during the past 3 months, but are covered by an announced
	aggregate. These prefixes are likely to be due to previously
	registered and announced prefixes that are now aggregated and
	no longer individually announced. Route dumps are taken at all
	border routers within ANS every 1-2 days.

	Below is the set of 1417 origin AS under which these route
	objects are registered.  [ ... table follows ... ]

Please clean up your own origin AS.  We'll be cleaning up the no
longer announced prefixes in our origin AS and customer AS.
