Re: IPv6 end user addressing

It isn't hard to do some arithmetic and guess that if every household
in the world had IPv6 connectivity from a relatively low-density
service like the above example, we would still only burn through about
3% of the IPv6 address space on end-users (nothing said about server
farms, etc. here) but what does bother me is that the typical end-user
today has one, single IP address; and now we will be issuing them 2^16
subnets; yet it is not too hard to imagine a future where the global
IPv6 address pool becomes constrained due to service-provider
inefficiency.


what is the life expectancy of IPv6?  It won't live forever and we
can't reasonably expect it too.  I understand we don't want run out of
addresses in the next 10-40 years but what about 100? 200? 300?

We will run out and our decedents will go through re-numbering again.
The question becomes what is the life expectancy of IPv6 and does the
allocation plan make a reasonable attempt to run out of addresses
around the end of the expected life of IPv6.
