[arin-ppml] [Fwd: Draft Policy 2011-5: Shared Transition Space for IPv4 Address Extension]
I would support change number 1.
I would argue that change number 2 is unnecessary and potentially harmful.
Why should 9 ISPs who have made very large use of this space suddenly have
it revoked simply because they are the last 9 to deprecate its use?
