This can't possibly be correct. The last figure I read was that there are
about 70k /24s. There are about 21k AS numbers out there. This means that
by far most of the announcements, including /24s, are the result of lack
of CIDR. Either because ISPs have a relatively large number of PA blocks
(address conservation) or because of lack of aggregation.
