[sig-policy] prop-105-v001: Distribution of returned IPv4 address blocks



Dear SIG Members

The proposal "prop-105-v001: Distribution of returned IPv4 address
blocks (Modification of prop-088)' has been sent to the Policy SIG for
review.

It will be discussed at the Policy SIG at APNIC 35 in Singapore,
Thursday 28 February 2013.

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?

prop-105-v001: Distribution of returned IPv4 address blocks
               (Modification of prop-088)

----------------------------------------------------------------------

1. Introduction
---------------

After the final /8 policy is implemented, IPv4 address blocks received
by APNIC are handled as being part of the final /8 pool and to
redistribute these resources according to the final /8 policy
(prop-088). This policy proposes to define a separate distribution
policy for all non-103 IPv4 address blocks in the APNIC pool, to start
the distributions once "Global policy for post exhaustion IPv4
allocation mechanisms by the IANA" is activated.


2. Summary
----------

While rapid implementation of IPv6 is in progress throughout the APNIC
region, demands for IPv4 address still continue. According to our survey
conducted to the APNIC community, over 70% of the respondents expressed
the needs to receive IPv4 address space, if a separate distribution
policy is defined from the final /8 policy.

In May 2012, the global policy âGlobal Policy for Post Exhaustion: IPv4
Allocation Mechanisms by the IANAâ was ratified by ICANN board, and it
will be implemented soon. Based on this policy, IPv4 address space
returned to IANA will be distributed to RIRs, and its size is not
expected to be so large but substantial enough to be able to consider an
additional minimum allocation for APNIC members.

Currently, these address blocks will be added to the reserve for
distributions according to the final /8 policy, in addition to 103/8
block already reserved for the purpose. Therefore, even if additional
blocks are added in APNIC's pool while reserves remain in the 103/8
block range, it is reserved for distribution under the final /8 policy.
We propose to distribute this newly received address block and address
blocks returned to APNIC to APNIC account holders.


3. Situation in other RIRs
--------------------------
-----------------------------

ARIN: no final /8 like policy.

RIPE-NCC: similar /8 policy.


4. Details
----------

Modify prop-088 to distribute non-103 IPv4 address blocks to APNIC
account holders who meet the IPv4 distribution criteria define in APNIC
policies.

If APNIC account holder, who was allocated an /22 from final /8 pool,
needs an additional IPv4 address block, they are eligible to receive
another distribution of IPv4 block.

The same policy as the final /8 policy will be appied in terms of the
criteria and the size of the distribution given the requestor has
utilized a total of /22 block from 103/8.


This policy will be effective after allocation of returned IPv4 address
blocks from IANA, based on "Global policy for post exhaustion IPv4
allocation mechanisms by the IANA".

The distribution policy for 103/8 block will remain unchanged, based on
the final /8 policy.


5. Pros/Cons
------------

Advantages: Able to utilize non-103/8 address pool in APNIC for
immediate distribution, instead of keeping as a reserve, in addition to
103/8.

Disadvantages: Some may feel the concern that adopting this policy
discourages IPv6 deployment in the APNIC region. However, according to
our survey, majority of the respondents responded revising the policy
does not impact their IPv6 deployment plan.



6. Effect on APNIC
------------------

APNIC account holders can obtain one more IPv4 block of minimum
allocation size as the upper limit (currently /22).



7. Effect on NIRs
-----------------

NIRs can choose whether to implement this policy or not.
