Which is fairly meaningless since half those 202 are instead delegated
to Large Organisations, Various Registries etc.
As has been stated things start getting hairly in about 10 years or so.
Less if IP enabled Cellphones start taking off, consider what is going to
happen in 5 years time if half the worlds population has an always on
ip-enabled cellphone and wants to run p2p apps talking to N arbitary other
hosts around the world.
As the cost of putting a full IP stack and connection drops to only a
couple of dollars or less all sorts of random things will start having
them. And before you say NAT remember that the power company will want to
directly access your meter and hotwater cylinder, your car company the
car, your whiteware company the fridge etc. Did I mention the games
When stuff like that comes along we really want them to be deployed on a
nice ipv6 internet rather than have to suddenly switch cause demand
increases by a factor of 10 overnight.
