    heh, these days, lots of it is still tunneled, though through more
    conventional means. But yes, I should have been more clear. Just too
    used to seeing 2001::/16 and too lazy to figure out the proper
    terminology (The original topic is something I've been heavily testing
    lately while I figure out how closely I can get to customer edges and
    how they will react).

    Agreed, and thanks for correcting my post. Would hate for others to take
    my offhanded comments on addressing and use them in production apps.
