Re: North America not interested in IP V6

I have been plotting the IPv6 ASNs for some time. These should be the
ISPs running IPv6. See:
http://www.nlnetlabs.nl/ipv6/measurements/index.html

It would be interesting to see an analysis that combines this data with 
Geoff Huston's IPv4 analysis
http://www.potaroo.net/ispcolumn/2003-07-v4-address-lifetime/ale.html
and see if we can predict the point at which the number of IPv6 addresses 
deployed begins to exceed the number of IPv4 addresses deployed? I realize 
that  the IPv6 analysis is routes only, but one should be able to 
determine how many addresses are available in each ASN.

One could reasonably assume that at the point where the Internet shifts to 
IPv6 as the core protocol, more than half of the interfaces with an IPv4 
address will also have an IPv6 address. So to get to that point, one could 
make some assumptions about the allocation of IPv6 /48's based on the 
observed trends in IPv4 /32's.

I'm not sure where one would take this, but I think a lot of people would 
be interested in seeing some type of well-presented analysis of these 
questions.
