a /56 is a tad over 1000 networks, each the size of the entire IPv4 space.
this is a little fallacy we keep playing on ourselves. it is only usefully true if you think you will be deploying absolutely jigongous layer two flat networks of O(2^64) size. and we all know that's not possible. or are you suggesting that we all throw the /64 magic lan boundary back in the ietf's face at this late date? while this would not break my little black heart, i don't think it's very likely to succeed. randy
