[rpd] IPv4 Soft Landing-bis Statement Post AFRINIC-26

[Omo Oaiya]

Dear Community,

On 9 February 2016, we initiated a policy proposal to update the IPv4 Soft
Landing policy (SL) adopted in 2011 and which followed the Global IPv4 soft
landing policy that granted the 102/8 to AFRINIC in February 2011

The existing Soft landing policy defines how to fairly distribute the 102/8
and other remaining v4 space to support a smooth transition to IPv6.  It
defines 2 phases (phase 1 and Phase 2) and keep a reserve of /12 for
unforeseen future. More detail at
http://www.afrinic.net/library/policies/1829-afrinic-consolidated-policy-manual#SoftLanding

The IPv4 Softlanding-Bis (SL-Bis) proposal aimed to make the distribution
more equitable based on AFRINIC IPv4 allocation/assignment statistics. It
stayed in the spirit of the Soft Landing policy (Need based allocations,
fair distribution, no limit on request from members) with the following
changes:

- reduce the max allocation/assignment in phase 1 from /13 to  /18 ([latest
version]

- change nothing in Phase 2

- remove the minimum allocation of /24 and empower staff to determine the
minimum as we go through the exhaustion and the transition to IPv6

- cancel the unforeseen future reserve(to be used at BoD discretion) and
create a dedicated reserve  for IPv6 deployment[ latest version] :

- allocation/assignment to root ops and  African ccTLDs operating in the
region for dual stack  DNS servers

- v4 space for new comers with IPv6 network for 464XLAT/ transition
mechanisms

On 12 February 2016,  a policy proposal named “Soft Landing
Overhaul”(SL-overhaul) was submitted. Section 2.0 of the proposal reads

======

2.0 Summary of How this Proposal Addresses the Problem

This proposal still maintains a block of space reserved for new entrants,
but beyond that, it allows for the natural depletion of IPv4 through
standard demand, and hence encourages the uptake of IPv6 in a more
aggressive manner.

The two proposals were presented at AFRINIC24 held in Gaborone (June 2016).
Despite the fact that many participants supported SL-Bis proposal, the
chairs declared that none of the 2 proposals got consensus.

During AFRINIC-25 held in Mauritius (November 2016), to avoid the Gaborone
scenario, the authors of SL-Bis offered to work together with the authors
of SL-overhaul to find a common ground about how to update the SL policy
despite the differences in the problem statements of the two proposals.

SL-overhaul authors withdrew their proposal thereafter and the
consolidation attempts by the Co-chairs produced the following document -
https://goo.gl/AWCCWd

The Chairs called for volunteers to take on points from that document and
propose policy while SL-bis was still in the PDP track.  As a consequence,

Soft Landing SD (SL-SD) was proposed on 30th March 2017. Section 2.0 of the
proposal reads:

 =======

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.

=========

The proposal modifies section 5.4.4 of the CPM to the following:

==============

For any LIR or End User requesting IPv4 address space during the Exhaustion
phases:

5.4.4.1 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.

5.4.4.2 Notwithstanding 5.4.4.1, an organisation that has received the
maximum allowable prefix in each phase may request for another round of
allocation/assignment in the same phase (as per 5.4.4.1), after 24 calendar
months waiting period.

=====================

SL-BIS and SL-SD were presented at AFRINIC26 held in Nairobi (May 2017). As
in Gaborone, the chairs declared no consensus for the 2 proposals despite
the overwhelming support for SL-BIS.  The SL-SD team withdrew their
proposal which only got support from author present.. See withdrawal
message at https://lists.afrinic.net/pipermail/rpd/2017/006924.html

Some discussions have occurred on the list after the AFRINIC26 meeting
about consolidating Soft landing policy update around SL-bis, etc…

In conclusion, if the chairs got the message from the community and are
ready to vary the PDP as per section 3.6 of the CPM, the authors will
happily work on submitting an update of SL-bis.  Otherwise, the authors
consider that based on the timing of the exhaustion phases and current PDP
process, we have reached a juncture at which a further update has
diminished value. As such, we would find it more productive to work
separately on aspects of the Soft landing that do not have time constraints
and can still go through the normal PDP.

The authors thank you all for your contribution and support all along the
SL-bis journey.
