Internet2 is a consortium of universities developing high speed networks. They have a working group for IPv6
I can totally see an ISP getting a bunch of IPv6 addresses. The ISP can be assigned more than it will ever need and there will be enough.
There are a few IPv4 addresses available. Which is good because it will be a long time before all infastructure switches. There is tunnelling though IPv4, but in perhaps 5 years IPv6 will really take off.
The main reason I like IPv6 is the sheer overkill of IP addresses. We're not going to run out of them.
I still don't understand it fully, though.
