No - but it is *phenomenally useful* if it does. Changing addresses is only ever something you want in very specific circumstances.
Bottom line... there's no pressing reason to make the jump, and a whole bunch of reasons to hold off. But you don't seem to care about any of that -- we should all continue driving our pintos with the exploding gas tank until your local shop has time to replace it. No. Thanks.
Wow, that's a metaphor that has been not merely mixed, but shaken and stirred as well. Are you for a move to IPv6 now or not? Is the Pinto IPv4 or IPv6? What does the exploding gas tank represent? If you mean we should hold off on moving to IPv6, then I disagree strongly. Here's a quote I like (because it's mine :-) "[...] the storm clouds have well and truly gathered, thunder is rolling in the hills, great big rain drops are splotting into the dust all around us, and what are we doing? Wandering around the outside of the Ark tut-tutting about the quality of the woodwork and loudly suggesting the construction of various sorts of rowboats." For what it's worth, I actually agree with you that 64 bits is way too short a prefix for the job. 80 would have been better, and some framework for *choosing* the prefix length and (say) hashing the MAC would have been even better. As it does you, the waste offends me, because I DO think we are repeating an IPv4 mistake. On the other hand - we have DHCPv6 to work around it. Noone HAS to use SLAAC. DHCPv4 is in every piece of home kit these days, with useful defaults, there's no show-stopper reason that DHCPv6 cannot do the same job. With a bit of work it could do a much better job.
