Draft Policy ARIN-2019-17: Returned Addresses to the 4.10 Reserved Pool

Problem Statement:

An inconsistent and unpredictable stream of address space is an 
unsuitable method of populating the waiting list (4.1.8.1) and 
fulfilling subsequent requests.

Policy statement:

Change "4.10. Dedicated IPv4 Block to Facilitate IPv6 Deployment" to 
"4.10 Dedicated IPv4 Pool to Facilitate IPv6 Deployment"

Change" 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. Allocations and assignments from this block " to "In 
addition to the contiguous /10 IPv4 block set aside and dedicated to 
facilitate IPv6 deployment, all returns and revocations of IPv4  blocks 
will be added to the pool of space dedicated to the facilitation of IPv6 
deployment. Allocations and assignments from this pool "

Change "This block will be subject to a minimum size allocation of /28 
and a maximum size allocation of /24. ARIN should use sparse allocation 
when possible within that /10 block." to "This pool will be subject to a 
minimum size allocation of /28 and a maximum sized allocation of /24. 
ARIN should use sparse allocation when possible within the pool."

Comments:

Timetable for implementation: Immediate
