So far there has been very little discussion on this policy.

Therefore, as one of the AC shepherds for this policy I would like to 
initiate some discussion of this policy.  Here are a few questions for 
the ARIN community to think about and provide feedback on;

- The current CI reservation is for all CI not just IXPs, the problem 
statement discusses growth primarily in the IXPs as justification to 
expand the reservation.  Should we split off a separate reservation pool 
for IXPs?  Or, keep the current common CI pool?

- ARIN-2011-4 the policy that made the original CI reservation had a 
Policy Term of 36 Months following implementation, but this was not in 
the policy text itself and therefore did not get included in the NRPM.


If applicable, this would have expired July 2014.  So, should there be 
expiration date included in this policy text?  If there should be no 
expiration date, should we explicitly note the removal of any expiration 
date in the discussion of this policy?

- There was discussion of smaller and larger than /24 IXP allocations, 
like /26 on the smaller side and that some very large IXPs are starting 
to need as large as a /22.  Also discussed was, sparse allocation for 
IXPs to allow expansion without renumbering.  Should this policy 
includes any changes along these lines?  Why or why not?

- Should we try to get this to the PPC at NANOG 63 in San Antonio as a 
Recommended Draft Policy?  Or should it wait go to the PPM at ARIN 35 in 
San Francisco as a Recommended Draft Policy?  What about ARIN free pool 
run-out timing?

Do you support the policy as written, if not are there any changes that 
could be made that would allow you to support the policy?
