Dear SIG members,
Version 2 of the proposal, 'IPv6 deployment criteria for IPv4 final /8
delegations', has been sent to the Policy SIG for review. This proposal
has been revised by the authors based on feedback received from the
community at APNIC 28 and on the Policy SIG mailing list. Please note
that as part of the revision, the title of the proposal has also been
changed.
Version 2 of the proposal will be presented at the Policy SIG at APNIC
29 in Kuala Lumpur, 1-5 March 2010.
We invite you to review and comment on the proposal on the mailing list
before the meeting.
The comment period on the mailing list before an APNIC meeting is an
important part of the policy development process. We encourage you to
express your views on the proposal:
- Do you support or oppose this proposal?
- Does this proposal solve a problem you are experiencing? If so,
tell the community about your situation.
- Do you see any disadvantages in this proposal?
- Is there anything in the proposal that is not clear?
- What changes could be made to this proposal to make it more
effective?

Version: 2

1. Introduction
----------------
This policy proposal seeks to ensure account holders use IPv4 addresses
from the final /8 space for transitioning to IPv6. The proposal
supplements the final /8 policy [1] by requiring applicants to
demonstrate IPv6 deployment needs or a transition plan.
The intent is to stimulate native IPv6 deployment as much as possible,
while supporting the need for future networks to communicate with the
IPv4 world.
2. Summary of the current problem
----------------------------------
The Internet will use IPv4 for many years during the adoption of
IPv6. During this period, account holders will need to connect to the
IPv4 Internet while they deploy services using the IPv6 Internet.
The final /8 policy[1] has the objective of assisting account holders to
participate in the IPv4 Internet while they deploy services using the
IPv6 Internet. However, the final /8 policy does not specifically
require account holders to demonstrate IPv6 deployment needs or a
transition plan.
This means that under the current final /8 policy, small account holders
could use their /22 allocation gained under the policy to grow IPv4
services and not to begin the transition to IPv6.
To make the message clear and ensure IPv4 space will remain available
for account holders' IPv6 deployment, this policy proposal seeks to
ensure account holders use the final /8 space for IPv6 transition.
3. Situation in other RIRs
---------------------------
AfriNIC has a similar policy proposal under discussion:
AFPUB-2009-v4-003: IPv4 Soft Landing Policy
http://www.afrinic.net/docs/policies/AFPUB-2009-v4-003.htm
ARIN has adopted a similar policy:
2008-5: Dedicated IPv4 block to facilitate IPv6 Deployment
https://www.arin.net/policy/proposals/2008_5.html
RIPE has similar policy proposal under discussion:
2009-04: IPv4 Allocation and Assignments to Facilitate IPv6
Deployment
http://www.ripe.net/ripe/policies/proposals/2009-04.html
LACNIC currently has no similar policy or proposal.
4. Details
-----------
It is proposed that to receive IPv4 addresses under the final /8 policy,
account holders must meet the following additional criteria:
1. The account holder must demonstrate either:
i. an IPv6 transition plan, OR
ii. IPv6 deployment needs, especially the needs for IPv6 to IPv4
internetworking.
2. The account holder must have either:
i. existing IPv6 addresses, OR
ii. a valid application for IPv6 addresses.
This proposal does not remove the existing conditions specified in the
current final /8 policy[2].
The /16 reserved for future uses[3] is exempted from the IPv6
requirement.
5. Pros/Cons
-------------
5.1 Advantages
- This proposal ensures account holders use the final /8 space for
IPv6 transition, supporting the needs for future networks to
communicate with the IPv4 world.
5.2 Disadvantages
- Some account holders will not be eligible to receive addresses
from the final /8 if their sole intent is to grow IPv4 services.
6. Effect on APNIC Members
---------------------------
This proposal requires APNIC account holders (existing and new) to
demonstrate IPv6 deployment needs or transition plan to receive IPv4
addresses from the final /8.
7. Effect on NIRs
------------------
This proposal will have the same effect on NIRs as it does on APNIC
Members.
