That IPv6 will be disaggregated into /40 or even /32 is disastrous.
It won't. No ISPs will deaggregate anything. Some multi-site enterprises might assign a /48 per remote site from their single prefix, and want those /48s routed via some transit peers. But this does not imply that their prefix is split into the maximum number of /48s. The number of routes is limited to the number of separate network sites. There is no need to worry about this number ever exceeding the number of IPv4 prefixes. And those /48s will most likely be filtered out of the global table forever. Enterprises wanting such a configuration will depend on special transit agreements to carry and aggregate them for the rest of the world. This is not a problem. There are real issues with dual-stack, as this thread started out with. I don't think there is a need neither to invent IPv6 problems, nor to promote IPv6 advantages. What we need is a way out of dual-stack-hell. Bjørn
