  • Amends:Soft Landing Policy - Section 5.4 of the CPM
  • Staff Assessment

1. Summary of the problem being addressed by this proposal

The current Soft-Landing Policy describes how AFRINIC should manage allocations and/or assignments from the last /8.

While the stated policy objective is to ensure that allocations/assignments are managed in a manner that is acceptable to the AFRINIC community, there is a general feeling from the AFRINIC community that certain provisions in the policy are not consistent with this objective.

Specifically, the current Soft-landing Policy:

a. Allows a maximum allocation size of a /13 in Phase 1. The authors feel that this is too large based on average allocation/assignment size of the last 5 years.
b. Allows organizations to request allocations/assignments without limiting the number of times or maximum size that can be requested. The authors of this policy feel this is not prudent management of the last /8 block.
c. Does not make any specific provisions for new entrants. The authors feel that AFRINIC should encourage new entrants during the exhaustion phase, especially if such measures don’t create significant barriers to existing members.


2. Summary of how this proposal addresses the problem

This proposal tries to address these problems by:

  • Reducing the maximum prefix in phase 1. We arrived at this figure by looking at the average allocation prefix. We found the average to be between /17 and /16.
  • Disallowing allocation to organisations who have been allocated up to the maximum prefixes during each phase for certain duration.
  • Adjusted the maximum prefix for phase 2, to bring it closer to average allocation size.


3. Proposal

Modify Section of the CPM to the following:
Exhaustion Phase 1:
During this phase, allocation/assignment of address space will continue as in the Current phase (/24 for a EU and /22 for a LIR) but the maximum will change from /10 to /16.

Modify Section of the CPM to the following:
Exhaustion Phase 2
During this phase, a minimum allocation/assignment size will be /24, and the maximum will be /20 per allocation/assignment.

Modify section 5.4.4 of the CPM to the following:
For any LIR or End User requesting IPv4 address space during the Exhaustion phases: An organization may request additional IPv4 address space in both Phase 1 and Phase 2. However, such an organisation's total allocations/assignments must not exceed the maximum allowable prefix of /16 for Exhaustion Phase 1 and /20 for Exhaustion Phase 2. Notwithstanding, an organization that has received the maximum allowable prefix in each phase may request for another round of allocation/assignment in the same phase (as per, after 24 calendar months waiting period.

Version 1.0

07 Apr 2017

Version 2.0

  • Modification of maximum prefix allowed during phase 1 based on staff analysis and community feedback
  • Modification of section 2 of the proposal, specifically to provide justification for change in prefix which is based on community feedback and staff analysis
  • Re-wording and renumbering of section 5.4.4,  specifically to provide more clarity based on community feedback and ensure that exhaustion is steady enough. It also ensures that new entrants are granted sufficient opportunity to acquire space by disallowing early return of existing members who have reached their maximum prefix in the respective phases.
  • Addition of revison history to section 4


01 May 2017

Version 3.0
Based on community feedback on the rpd list, the following modifications were done:

  • Modification of the problem statement to make it more clearer and less ambiguous.
  • Reduction of the wait period from 36 months to 24 months.

Proposal AFPUB-2017-V4-001-DRAFT-02
Title Soft Landing - SD
Assessed 15 May 2017


1.0 Staff Understanding of the Proposal

  • Proposal reviews some articles in the current Soft Landing policy to further make it consistent with the "soft landing" intent/spirit behind the original policy.
  • Reduces the maximum issuable prefix size in exhaustion phase 1 to /16
  • Sets the maximum issuable prefix size in exhaustion Phase 2 to /20 and minimum issuable prefix size to /24 per allocation/assignment.
  • Disallows allocation to organisations who have been allocated up to the maximum issuable prefix size during each exhaustion phase for 36 months. 


2.0 Staff Comments

  • Text in and are somewhat difficult to understand.
  • In, is the "total allocations/assignments" the total for that organisation over all time, or the total issued during a particular phase, or something else?
  • In, is the ability to "request for another round" restricted to only one additional round, or may there be more?
  • seems to be an exception to  They could be re-worded in such a way that no exception is needed.


3.0 Comments from Legal Counsel

None observed.


4.0 Implementation:

4.1 Timeline & Impact

The proposal can be implemented as written without significant impact to AFRINIC resources within the timeline recommended by the PDP.

4.2 Implementation Requirements

The following work shall be required from IT:

  • Codification of new minimum and maximum allocation sizes as well as allocation validity time (36 months) in MyAFRINIC and whois
  • Revision of Resource Request forms (in MyAFRINIC and NMRP)
