Re: [sig-policy] prop-111-v001: Request-based expansion of IPv6 default

5. Explain the advantages of the proposal

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

- It will be possible for LIRs to control traffic easier.

And I guess traffic is under control with existing minimum initial allocation.

- It is possible to use current reserved blocks efficiently.

The idea is to use the allocated block (no matter how big or small it is) efficiently.

6. Explain the disadvantages of the proposal

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

Some people may argue this will lead to inefficient utilization of

IPv6 space. However, the space up to /29 is reserved by APNIC

secretariat for each /32 allocation.

No, the argument is nothing is broken here to be fixed. Option is already there to request for larger then minimum initial allocation with proper justification. If the need is there to have larger address block then justification won't be an issue. The only purpose this policy serve is remove the "Justification" portion.

presented at the Policy SIG at APNIC 37 in Petaling Jaya, Malaysia, on

Thursday, 27 February 2014.

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?

prop-111-v001: Request-based expansion of IPv6 default allocation size

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

1. Problem statement

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

Currently, IPv6 minimum allocation size to LIRs is defined as /32 in

the "IPv6 address allocation and assignment policy", while APNIC

currently reserves up to /29 for each /32 allocation. It's better to

expand this minimum allocation size up to /29 since:

- For traffic control purpose, some LIRs announce address blocks

longer than /32 (e.g. /35). However, some ISPs set filters to block

address size longer than /32. If LIRs have multiple /32, they can

announce these blocks and its reachability will be better than

longer prefix.

- If an LIR needs address blocks larger than /32, LIRs may tend to

announce as a single prefix if a /29 is allocated initially at

once. i.e., total number of announced prefixes in case 1 may be

smaller than in case 2.

case 1:

The LIR obtains /29 at the beginning of IPv6 network construction.

case 2:

The LIR obtains /32, and /31, /30 additionally with the subsequent

allocation mechanism.

- Before sparse allocation mechanism implemented in late 2008, /29

was reserved for all /32 holders by sequence allocation mechanism

in the early years. It is possible to use these reserved

blocks efficiently with this modification.

2. Objective of policy change

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

This proposal modifies the eligibility for an organization to receive

an initial IPv6 allocation up to a /29 by request basis.

3. Situation in other regions

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

RIPE-NCC:

The policy "Extension of IPv6 /32 to /29 on a per-allocation vs

per-LIR basis" is adopted in RIPE-NCC and LIRs in RIPE region can get

up to /29 by default.

4. Proposed policy solution

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

- Change the text to "5.2.2 Minimum initial allocation size" of

current policy document as below:

Organizations that meet the initial allocation criteria are

eligible to receive an initial allocation of /32. For allocations

up to /29 no additional documentation is necessary.

- Add following text in the policy document:

for Existing IPv6 address space holders

LIRs that hold one or more IPv6 allocations are able to request

extension of each of these allocations up to a /29 without meeting

the utilization rate for subsequent allocation and providing

further documentation.

5. Explain the advantages of the proposal

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

- It will be possible for LIRs to control traffic easier.

- It is possible to use current reserved blocks efficiently.

6. Explain the disadvantages of the proposal

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

Some people may argue this will lead to inefficient utilization of

IPv6 space. However, the space up to /29 is reserved by APNIC

secretariat for each /32 allocation.

7. Impact on resource holders

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

NIRs must implement this policy if it is implemented by APNIC.
