        ah... but the trick is to only need enough IPv4 in the pool
        to dynamically talk to the Internet.  Native v6 to Native v6
        never has to drop back to the Internet, It uses native v6
        paths.  So the larger the v6 uptake, the fewer Internet addreses
        you'll need to keep around in your pool.
