[rpd] Proposal Update received: IPv4 Soft Landing-bis

Wed Apr 19 01:38:21 UTC 2017

It is unclear from the positioning and wording of 5.4.4 whether this applies beginning with the applicability of 5.4.3 (or rather at the implementation of this policy), or beginning upon triggering 5.4.3.2, or at some point after 5.4.3.2.

It’s also (IMHO) better if we define the beginning of exhaustion phase 2 as part of 5.4.3.2 rather than as part of 5.4.3.1.

I do commend the authors for addressing most of my concerns in redrafting this proposal. I’m still rather unconvinced that the problem statement represents an actual problem to be solved, but I am no longer so opposed to the adoption of the actual policy text.

I am opposed to allowing Core DNS service providers in 5.4.6 as they are not part of facilitating IPv6 deployment (or at least their IPv4 usage is not).

There is no limit to the number of times an organization may obtain a /24 under 5.4.6. I believe this is contrary to its intended use and purpose.

> 1.0 Summary of the Problem Being Addressed by this Policy Proposal
> The soft-landing policy ratified by the board on the 11/11/2011 describes how AFRINIC should manage allocations/assignments from the last /8. It defines 2 phases for the IPv4 exhaustion. During phase 1, it sets the maximum to be /13 instead of /10 and in phase 2, the maximum to /22 and the minimum to /24. It makes no difference between existing LIRs or End-Users and new ones. The policy also does not impose IPv6 deployment.
>  
> IPv4 exhaustion in other regions combined with other factors has imposed huge pressure on the AFRINIC IPv4 pool with requests for large IPv4 blocks, with very little IPv6 deployment. The pressure on the AFRINIC IPv4 pool has led to some policy proposals to reserve some blocks for certain sub-communities.

LIRs must be members of an RIR like AFRINIC; which serves the Africa Region and part of the Indian Ocean (Comoros, Madagascar, Mauritius, and Seychelles).

> 5.4.3 Exhaustion Phase
> During the Exhaustion Phase, the following allocation and assignment policy will be used. This policy applies to both LIRs and End Users, and applies to all IPv4 address space allocated, assigned, or otherwise managed by AFRINIC during the transition to and after the beginning of the Exhaustion Phase, regardless of whether or not such IPv4 address space is a part of the Final /8. The exhaustion phase will be divided into two parts:

> The allocation and assignment period shall be of 8 months. This will help to ensure that LIRs request only for resources they need in the short to medium term, and promote fairness in the equitable distribution of the last IPv4 address pool. This allocation/assignment period will remain the same throughout the life span of this Policy
>  
> 5.4.5 Allocation Criteria
> In order to receive IPv4 allocations or assignments during the Exhaustion Phase, the LIR or End User must meet IPv4 allocations or assignment policies requirements and have used at least 90% of all previous allocations or assignments (including those made during both the Pre-Exhaustion and the Exhaustion Phase).
> In the case of new LIRs or End Users with no previous allocations or assignments, this requirement does not apply to their first allocation or assignment request.
> AFRINIC resources are for AFRINIC service region and any use outside the region should be solely in support of connectivity back to the AFRINIC region
>  
> 5.4.6 IPv6 deployment reserve
> A contiguous /12 IPv4 address block will be reserved out of the Final /8 to facilitate IPv6 deployment. When AFRINIC, can no longer meet any more requests for address space (from the Final /8 or from any other available address space), allocations and assignments from this block must be justified by needs for IPv4 addresses space to support IPv6 deployment. Examples of such needs include: [IPv4 addresses for Core DNS service providers dual stack DNS servers, 464XLAT translators or any other translators as defined by the IETF. This block will be subject to a maximum size allocation of /24.
>  
> AFRINIC staff will use their discretion when evaluating justifications and should use sparse allocation when possible within that /12 block.
>  
> In order to receive an allocation or assignment from the IPv6 deployment reserve:
> The applicant may not have received resources under this policy in the preceding six (6) months;
> The applicant must demonstrate that no other allocations or assignments will meet this need.
