Dear SIG members
Version 2 of the proposal 'Removing aggregation criteria for IPv6 initial allocations' has been sent to the Policy SIG for review. It will be presented at the Policy SIG at APNIC 29 in Kuala Lumpur, 1-5 March 2010.
Information about this and other policy proposals is available from:
This new version of the proposal reflects feedback from the community received on the Policy SIG mailing list:
- The wording of section 4.1 has been changed to more closely reflect the current policy.
- The first advantage listed in section 5.1 has been amended following community feedback.
- Effects on APNIC members and NIRs have been added to sections 6 and 7.
We encourage you to express your views on the proposal:
- Do you support or oppose 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?

1. Introduction ----------------
This is a proposal to remove the aggregation requirement from the IPv6 initial allocation policy.
2. Summary of the current problem ----------------------------------
The initial IPv6 address allocation criteria requires that LIRs:
"Plan to provide IPv6 connectivity to organizations to which it will make assignments, by advertising that connectivity through its single aggregated address allocation."
However, there is no similar aggregation requirement in either the criteria for subsequent allocations, or in the new IPv6 allocation criteria for APNIC members.
Including the aggregation requirement is problematic for two reasons:
1. It is inconsistent the criteria for IPv6 allocations under two other APNIC policies, which do not require aggregation. These policies are:
- Subsequent IPv6 allocations - The new kick start IPv6 allocation criteria to be implemented 10 February 2010 
2. Registry policy should not concern itself strongly with routing issues.
3. Situation in other RIRs ---------------------------
The LACNIC community is currently discussing the following proposal to remove the requirement to announce an initial allocation as a single prefix in favour of announcing the prefix with the minimum possible level of disaggregation:
2007-01: Modifications to the IPv6 Prefix Initial Allocation Policy http://www.lacnic.net/documentos/politicas/LAC-2007-01v3-propuesta-en.pdf
The RIPE community has recently removed routing requirements from IPv6 policy:
2009-06: Removing Routing Requirements from the IPv6 Address Allocation Policy http://www.ripe.net/ripe/policies/proposals/2009-06.html
AfriNIC and ARIN initial IPv6 allocation criteria require a plan to aggregate, with no requirement for aggregation for subsequent allocation criteria. Neither RIR is has any proposal to modify these criteria.
4. Details -----------
This is a proposal to:
4.1 Remove the requirement under the initial IPv6 allocation criteria to advertise an initial allocation as a single (aggregate) prefix.
4.2 Include a stronger recommendation about the importance of aggregation to the IPv6 policy document.
The APNIC IPv6 policy document currently does include information about the importance of aggregation. However, it is the opinion of this proposal's authors that the recommendation should be more strongly expressed.
5. Pros/Cons -------------
- This policy reduces the number of requirements to obtain IPv6 address.
- Other RIR communities are discussing removing aggregation requirements from their policies, so it would be appropriate for APNIC policy to maintain similar criteria to other regions.
- By removing the aggregation requirement in the policy, deaggregated routes may begin to be announced more frequently.
6. Effect on APNIC members ---------------------------
APNIC members can apply for IPv6 addresses without ensuring aggregation.
7. Effect on NIRs ------------------
NIRs should remove the aggregation requirement from IPv6 initial allocation criteria.
