The most serious problem we're facing is NOT how to route to the existing allocations, but how we're going to route to all the new allocations that are due to the exponential growth of the Internet. With this in mind, why do you think that IPv6 allocation would be any different than CIDR IPv4 allocations (which is how all the new allocations suppose to be done) ? So far all the documents I've seen on IPv6 address allocation are quite similar to IPv4 address allocation documents. > that's the _plan_, mind you. I think this is not even "the _plan_". I think that is what some of us could wish be "the plan". Yakov.
