Re: [sig-policy] Final call for comments: [prop-031-v002] "Proposal to amend APNIC IPv6 assignment and utilisation requirement policy"

I am NOT favor for this change at this momemnt.
I see the mis-usage of HD-Ratio in the current operation.

Original intention of introducing "HD-Ratio" criterion
was to judge an applicant eligibility to receive sub-
allocation for minimizing the "Sub-allocation" judgement
overhead.
Not to decide the "size" of "Initial" allocation.
Before we change the "magic" number, we ought review the
current RIR operation of "Initial Allocation" application
process which is easily applying the HD-Ratio to decide
the allocation size even an applicant does not require
that size.

The following is my idea for the initial allocation.

1) to an applicant for initial allocation "without" any
   specific IPv6 deployment plan (network design), but
   an applicant has their intention to provide IPv6 service
   in near future
  -> allocate /32

2) to an applicant for initail allocation "with" their IPv6
   service plan and network design based on their current
   IPv4 customers
  -> judge the minimum initial allocation size just accomodating
     enough number of /48s in their planned.

for both cases:
     when the applicant need to expand the network size later,
     once they register enough number of /48s for sub-allocation
     criterion set by the HD-Ratio table, they can automatically
     have the sub-allocation block which is the same size of
     initial allocation as the current policy (i.e., the total
     block would be doubled)
     * in this case, HD-Ratio of 0.8 is good for LIRs.

Thanks

Dear colleagues
APNIC welcomes comments, questions, and suggestions on the following policy 
proposal:

____________________

Final call for comments: [prop-031-v002]
"Proposal to amend APNIC IPv6 assignment and utilisation requirement policy" 
____________________

This is the final call for comments on policy proposal [prop-031-v002]
"Proposal to amend APNIC IPv6 assignment and utilisation requirement policy". 

Version one of this proposal was discussed at APNIC 20. The proposal to
amend the IPv6 HD ratio from 0.8 to 0.94 reached consensus and is now
documented in [prop-031-v002]. Other parts of proposal [prop-031-v001]
did not reach consensus.

Regarding the amendment of the IPv6 HD ratio, the following consensus  was
reached:

   "The SIG accepted by consensus the proposed policy process,
    which requires the text proposal to be sent to the mailing
    list one month before the meeting, an eight week comment
    period on the mailing list after the meeting, and final
    endorsement from EC."

This proposal is now submitted to the sig-policy mailing list for an
eight week discussion period. At the end of that period, if consensus
appears to have been achieved, the Chair of the Policy SIG will
ask the Executive Council to endorse the proposal for implementation.

*   Send all comments and questions to:   <sig-policy@apnic.net>
*   Deadline for comments:                  16 November 2005

Authors:    Stephan Millet  <stephan (a) telstra.net>
            Geoff Huston    <gih (a) apnic.net>

Version:    2.0

Date:       19 September 2005

Purpose
-------

To amend the APNIC IPv6 address allocation policies regarding the
definition of the threshold value for end-site allocation efficiency.

These measures, if undertaken generally by all RIRs, and assuming that
further measures are undertaken by the addressing community regarding
the general adoption of an end-site allocation size that would be
substantially smaller than the existing default value of a /48, would
increase the anticipated useful lifetime of IPv6 to encompass a period
in excess of 100 years, in which case no further allocation policy
changes would be anticipated.


Proposal
--------

To amend the IPv6 threshold end site allocation utilisation level to
that matching an HD Ratio value of 0.94.


Impact summary
--------------

  End users:

    There is no impact arising from this policy proposal.


  ISPs and LIRs:

    With the higher threshold end-site allocation efficiency level,
    when based on a 0.94 HD Ratio, ISPs will need to undertake network
    address plans according to this target level.


  NIRs:
These proposed policy changes are not anticipated to have any impact on 
    NIR operation, other than implementation of a 0.94 density metric
    to replace the existing 0.80 value, as per APNIC policy.


  APNIC:

    APNIC will need to amend its IPv6 criteria to reflect the altered
    HD ratio.
