Hi, I support the concerns of Florian. We need addresses for addressing AND ROUTING. In the original design a few bits had been reserved for routing purposes in the IPv6 address scheme just to facilitate routing in the future. These bits completely disappeared -- which is not a a problem in the first phase of the transition, where we are now; however the missing functinality will case problems as the Internet will further grow. Jim, probably you are better expert in this field than me - what do you foresee about scaling of routing and the possibilities of chosing between different backbone service providers in the future?

If the Internet doles out a billion /64s every day -- several orders of magnitude more than any forseeable assignment rate -- it will take 50 million years to deplete the IPv6 address space. I'm happy to leave that problem to the next generation. :-)
There have been suggestions to use multiple /24s for each ISP using certain IPv6 deployment strategies. Exhaustion isn't so remote anymore if such efforts become widespread.
