They said that just before CIDR happened, too.
and CIDR bought us time to get a replacement ready.
From the routing-table summary posted to the NANOG list this morning:
Number of addresses announced to Internet: 1348239976
Equivalent to 80 /8s, 92 /16s and 130 /24s
Percentage of available address space announced: 36.4
Percentage of allocated address space announced: 58.8
Percentage of available address space allocated: 61.9
So 40% isn't even *allocated* yet (saying that we're probably burning /8's
faster than needed, but only 36% of the available space is actually
Sounds to me like we've got more time than 52 months, if we start doing
stuff now to increase the usage efficiencies....
Despite the desire to look for indicators that preclude having to learn
something new, it really doesn't matter how much of the space is routed.
What matters is the day someone new shows up to acquire space they intend to
route, only to find the reservoir dry. The number of routing entries is an
interesting operational measure, but what counts from a protocol viability
standpoint is the remaining useful space in the IANA pool.
We can always extend the lifetime of IPv4 by restricting the allocation
policies. The point is it is long past time to wake up and face the reality
that stricter conservation is directly contrary to expanding the reach and
capabilities of the global Internet. The IETF needs to be about developing a
growing and vibrant Internet, so resisting the inevitable change is counter
productive. In that light, it is time to remove the special status of
separate working groups for IPv6, and make it the default IP protocol for
all IETF work.
