      Hi Randy
      thanks for your comments.
      fully agree to them, and I also have
      another reason to be concerned.
      there is a higher chance of being hijacked
      with 1/8 then with others because of the
      naughty usage of the /8 in the past.
      I seriously doubt these people that misbehave
      check allocation status.
      There's more but I won't go on.
      For now, I cannot think of a good way to
      go about this. If we had RPKI now,
      this would be one less worry...
      I think they are doing testing right now, but
      it would feel a bit more comfortable if APNIC handed out
      1/8 after they've done with 27/8.
      Any others that have suggestions?
