The big difference between IPv4 initial policies and IPv6 initial
policies is that with IPv4 there were no policies to speak of in the
early days. Space was handed out more or less willy-nilly - so some US
organisations ended up with multiple A-classes each, while later on all
of Vietnam got one /26.

With IPv6 there is a policy, it's been there from day one, it's well
thought out, and if followed will see everyone (yes EVERYONE) getting
vastly more address space than they are ever likely to need *even if our
wildest expectations are exceeded*.

Four billion isn't really that much. It never was. It was obvious
decades ago that it would run out. IPv6 was designed with that in mind.

That's the big difference - IPv6 has been designed to provide abundant
address space. Restrictions like /56 instead of /48 are unnecessary
limitations - limitations that the protocol was designed to remove!
