It's that kind of weasel-wording that I object to. The words "up to"
make this wording directly contradict RFC 3177. The addition of a /56
size for consumer sites is a minor change to the IPv6 addressing
architecture which has support within the IETF. But your statement about
/128's etcetera is in direct contradiction to the IPv6 architecture.

IPv6 is *NOT* the same as IPv4.
