[arin-ppml] Draft Policy 2011-5: Shared Transition Space for IPv4 Address Extension - IAB comment

[John Curran]

On February 15th, the following update to staff assessment for Draft Policy 
2011-5 was made:

> 

> In keeping with the spirit of RFC 2860 with respect to the assignment
> of specialized address blocks, ARIN Staff will consult with the IANA and
> the IAB regarding implementation of this draft policy.

Please find attached correspondence regarding consultation with the IAB on 
Draft Policy 2011-5 "Shared Transition Space for IPv4 Address Extension". 
The ARIN Board will consider this response and the recommendation to adopt 
2011-5 at an upcoming meeting.  It is quite possible that this will result 
in the policy proposal being referred to the IETF for reconsideration, and 
any parties interested in this Draft Policy should note this possibility 
for purposes of planning their ongoing efforts in this area.

FYI,
/John
