So, Benny is turning it upside down - instead of asking the registry for a number, we tell the registry which number we'd like (and the registry will say no if the number is already registered). It would work, but I don't see any particular advantage over having the registry pick a number. It's a

I actually see a lot of value in the /56 proposal; I really like the simplicity of creating the /56 from any MAC-48 in the network. It accomplishes the uniqueness property without requiring central registration, and should serve organizations up to considerable size very well. And it readily
