I would like to join the chorus of applause for Interop's generosity. I 
agree with those who've said that this only buys us a little more time, 
but they did the right thing, and we should applaud them for that; along 
with the DOD and others who have returned their unneeded space.

As for the fact that the block was released to ARIN as opposed to going 
back in the free pool, the effect may ultimately be the same. 
Allocations from IANA to the RIRs happen under the policy posted at 
http://www.icann.org/en/general/allocation-IPv4-rirs.html. The 
determination of when to allocate a new /8 is based on the amount of 
free space that the RIR has on hand at the time of the request. There 
are 12 /8s remaining atm, and 5 of those will automatically be allocated 
1 per RIR when the other 7 have been allocated under the normal policy. 
I am confident that ARIN will also do the right thing here and include 
the /8 from Interop in their free space calculation before requesting an 
allocation of one of the 7 /8s in the free pool.

hth,

Doug
