If the answer is zero (because you are still allocating from smaller blocks), how much CI space has been allocated in the last year? If I'm reading </span><a href="https://www.arin.net/knowledge/micro_allocations.html">https://www.arin.net/knowledge/micro_allocations.html</a> right, it looks like you have issued a total of about 1.2 /16 equivalents for CI, plus another 0.3 /16 equivalents for IXPs.</div>

<br>
ARIN received the following policy proposal and is posting it to the<br>
Public Policy Mailing List (PPML) in accordance with the Policy<br>
Development Process.<br>
<br>
The ARIN Advisory Council (AC) will review the proposal at their next<br>
regularly scheduled meeting (if the period before the next regularly<br>
scheduled meeting is less than 10 days, then the period may be extended<br>
to the subsequent regularly scheduled meeting). The AC will decide how<br>
to utilize the proposal and announce the decision to the PPML.<br>
<br>
The AC invites everyone to comment on the proposal on the PPML,<br>
particularly their support or non-support and the reasoning<br>
behind their opinion. Such participation contributes to a thorough<br>
vetting and provides important guidance to the AC in their deliberations.<br>

ARIN-prop-177 Revising Section 4.4 C/I Reserved Pool Size<br>
<br>
Proposal Originator: Martin Hannigan<br>
<br>
Proposal Version: 1.0<br>
<br>
Date: 27 JUNE 2012<br>
<br>
Proposal type: NEW<br>
<br>
Policy term: PERMANENT<br>
<br>
Policy statement:<br>
<br>
Change Section 4.4 Paragraph 2 from:<br>
<br>
ARIN will place an equivalent of a /16 of IPv4 address space in a<br>
reserve for Critical Infrastructure, as defined in section 4.4. If at<br>
the end of the policy term there is unused address space remaining in<br>
this pool, ARIN staff is authorized to utilize this space in a manner<br>
consistent with community expectations.<br>
<br>
Change Section 4.4 Paragraph 2 to:<br>
<br>
ARIN will place an equivalent of a /15 of IPv4 address space in a<br>
reserve for Critical Infrastructure, as defined in section 4.4.<br>
<br>
Rationale:<br>
<br>
Additional critical infrastructure is being added to the Internet and<br>
in a number greater than anticipated. The original CI pool was created<br>
to serve new IX and new CI requirements. The pending need is estimated<br>
in the 600 new gTLD range. With a /24 assignment from the existing<br>
boundary and the likelihood of some sharing platforms, assigning a /15<br>
would seem prudent. I also have removed the limited term. If at a<br>
later date we opt to remove or reduce the pool, it's simpler to do so<br>
without an extra step, namely the term. The process for completing the<br>
additions still has some time to play out, but it is likely we will<br>
have exhausted by the time that the process does fully play out.<br>
