Hi all, I'm David Chen. I would like to confirm that if IPv6 HD ratio is amended from 0.8 to 0.94, will the utilisation be changed to a higher number under HD 0.94 in the fee schedule? As I know in the APNIC fee schedule, IPv6 per-address fee is calculated according to current HD ratio requirement. http://www.apnic.net/docs/corpdocs/member-fee-schedule.html. Following this rule, it would be a big influence on per-address fee. For example, The utilisation number of /48s for /32 under HD ratio 0.8 is 7,132. The total per-address fee payable for an allocation of /32 to a "Very Large" member is calculated as : 7,132 * 0.03 = $213.96 If under HD ratio 0.94, then the utilisation number of /48s for /32 is around 33,690. The total per-address fee payable for an allocation of /32 to a "Very Large" member is calculated as : 33,690 * 0.03 = $1,010.7 Am I right? Please clarify this for me, 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

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.
