Policy Proposal Name: Revising Section 4.4 C/I Reserved Pool Size
name: Martin Hannigan
email: hannigan at gmail.com
organization: Elected ARIN Advisory Council Member
Proposal Version: 2.0
Date: 10 JULY 2012
Proposal type: NEW
Policy term: PERMANENT
Implementation: When the equivalent of less than a /8 is left in ALL
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.
Additional critical infrastructure is being added to the Internet and
in a number greater than anticipated when this proposal was written
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 have removed the limited
term. I have proposed implementation to occur at the point where there is
only an equivalent of a /8 available overall. The process for
gTLD 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.
