ARIN-prop-177 Revising Section 4.4 C/I Reserved Pool Size

Proposal Originator: Martin Hannigan

Proposal Version: 1.0

Date: 27 JUNE 2012

Proposal type: NEW

Policy term: PERMANENT

Policy statement:

Change Section 4.4 Paragraph 2 from:

ARIN will place an equivalent of a /16 of IPv4 address space in a
reserve for Critical Infrastructure, as defined in section 4.4. If at
the end of the policy term there is unused address space remaining in
this pool, ARIN staff is authorized to utilize this space in a manner
consistent with community expectations.

Change Section 4.4 Paragraph 2 to:

ARIN will place an equivalent of a /15 of IPv4 address space in a
reserve for Critical Infrastructure, as defined in section 4.4.

Rationale:

Additional critical infrastructure is being added to the Internet and
in a number greater than anticipated. The original CI pool was created
to serve new IX and new CI requirements. The pending need is estimated
in the 600 new gTLD range. With a /24 assignment from the existing
boundary and the likelihood of some sharing platforms, assigning a /15
would seem prudent. I also have removed the limited term. If at a
later date we opt to remove or reduce the pool, it's simpler to do so
without an extra step, namely the term. The process for completing the
additions still has some time to play out, but it is likely we will
have exhausted by the time that the process does fully play out.
