You are encouraged to discuss the merits and your concerns of Draft
Policy 2014-16 on the Public Policy Mailing List.

The AC will evaluate the discussion in order to assess the conformance
of this draft policy with ARIN's Principles of Internet Number Resource
Policy as stated in the PDP. Specifically, these principles are:

Draft Policy ARIN-2014-16
Section 4.10 Austerity Policy Update

Date: 16 May 2014

Problem Statement:

NRPM section 4.10 defines an IPv4 to IPv6 transition pool which was 
intended to be used by new entrants after the IPv4 free pool has been 
exhausted. This policy was written prior to exhaustion in the APNIC and 
RIPE region and has largely not been used to date. It is believed that 
the current policy may be too restrictive to be useful to many 
organizations within the ARIN region. Furthermore the during the ARIN 33 
public policy meeting experience report (1), ARIN staff noted issues 
with the current IPv4 policy after the IPv4 free pool is exhausted.

RIPE & APNIC adopted an “austerity” policy which allows organizations to 
obtain a small single block directly from the registry. These policies 
appear to have been quite effective at getting IPv4 resources to 
organizations without address space after IPv4 exhaustion. Learning from 
other regions, we have crafted a policy to update section 4.10 to adopt 
some of the policy text from the RIPE & APNIC region while looking at 
the unique aspects of the ARIN region’s number resource needs.

Policy statement:

Replace Section 4.10 with the following policy.

4.10 Dedicated IPv4 block to facilitate IPv6 Deployment

When ARIN receives its last /8 IPv4 allocation from IANA, a contiguous 
/10 IPv4 block will be set aside and dedicated to facilitate IPv6 
deployment and continued transition from IPv4 to IPv6.

Address space received from IANA under the “Global Policy for Post 
Exhaustion IPv4 Allocation Mechanisms by the IANA (NRPM 10.5)” by ARIN 
shall be allocated or assigned under this section.

Allocations and assignments from this block must be justified by 
immediate IPv6 deployment requirements. Organizations must obtain an 
IPv6 block to receive a block under section 4.10 and show documentation 
on how the IPv6 and IPv4 block will be used to facilitate an 
organization’s operational needs.

This block will be subject to a minimum size allocation of /28 and a 
maximum size allocation of /22. ARIN shall use sparse allocation within 
these blocks.

In order to receive an allocation or assignment under this policy:

1. the organization, nor it parent(s) or subsidiary organizations, may 
not have received IPv4 resources greater than or equal to a /22 from 
ARIN or any other RIR;

2. the organization must show immediate use (within 30 days) of 25% of 
the allocation;

3. the organization is eligible to receive only one contiguous IPv4 
block under this section;

4. the organization may apply to ARIN for an increase in their 
allocation up to a /22, if the previous allocation under this section 
shows a utilization of at least 80%, increases will only be granted if 
adjacent bit-boundary aligned space is available at the time of request.


a. Timetable for implementation: immediately

b. Anything else: (1)
