(The numbers represent the number of addresses used up in that year as a percentage of the 3.7 billion total usable IPv4 addresses.)

Those years where the growth was smaller than the year before never happened twice or more in a row.

This basically means that unless things take a radical turn, the long- term trend is accelerating growth so that remaining 40% will be gone in less than 9 years. Probably something like 7, as Geoff Huston predicts.



        This is much less time than I have seen in previous reports. If
this is accurate and consistent there is a greater problem than I had
previously thought.
        If that is indeed the case then the "enhanced nat" road for ipv6
begins to make much more sense, even in the nearer term.

I am afraid the problem is even bigger.

I have seen again and again that cable providers are giving out
ip-addresses in the 10.0.0.0/8 area to save ip address space.

Not to mention wireless hotspots. The hotspots I have been playing
with own only a single one ip-address.

You notice something is awfully wrong, when your VoIP phone is not
working but your neighbar keeps telling you, his skype does.
