Douglas,
Looks good overall. A few comments/suggestions inline... (You can take
them or leave them as you wish. I have no definitive opinions either
way: I just wanted to throw out some suggestions based on previous
experience with similar policies in our region.)

As Policy author, i hereby submit the policy for further review; your
comments on the same are welcome.
==============================================================
Incentive
------------
In order to ensure a flexible transition from IPv4 to IPv6, the
lifespan of IPv4 can be increased in order to give network operators
more time to make the transition. This document proposes a strategy
for allocation and maintenance of AfriNIC's final /8 block of IPv4
from IANA.
Background
---------------
Following the much anticipated IPv4 pool exhaustion, a global policy,
"Global Policy for the Allocation of the Remaining IPv4 Address
Space", has been ratified. The policy ensures that IANA reserves one
(1) IPv4 /8 address block for each RIR. Details of the Global Policy
for the Allocation of the Remaining IPv4 Address Space can be found
at: http://www.afrinic.net/docs/policies/afpol-v4gp200802.html.
This policy (IPv4 Soft Landing) applies to the management of address
space that will be available to AfriNIC under the Global Policy
The purpose of this document is to ensure that this last block will be
used in a manner that is acceptable by the AfriNIC community.
Policy Documents to be affected:
--------------
(a) IPv4 Allocation Policy
http://www.afrinic.net/docs/policies/afpol-v4200407-000.htm
(b) Proposal to Change the Allocation & Assignment Period to 12 months
http://www.afrinic.net/docs/policies/afpol-af200611.htm
Definitions
--------------
(a) Local Internet Registry (LIR)
A Local Internet Registry (LIR) is an Internet Registry (IR) that
receives allocations from an RIR and primarily sub-allocates or
assigns address space to 'end-users'. LIRs are generally ISPs. Their
customers are other ISPs and possibly end-users. LIRs must be members
of an RIR like AfriNIC; which serves the Africa Region and part of the
Indian Ocean (Comoros, Madagascar, Mauritius, Seychelles).
(b) Existing LIR´s An existing LIR is defined as being an organization
that
assigns address space to 'end-users' and who has already been
assigned or allocated
IPv4 address space by AfriNIC.
(c) New LIR´s A new LIR is defined as being an organization that
assigns address
space to 'end-users' and who is a member of AfriNIC but has not
been assigned or
allocated any IPv4 address space prior to the Exhaustion phase.
Summary
------------
This proposal describes how AfriNIC shall allocate and manage IPv4
resources from the last /8 block of IPv4 address allocated by IANA at
the time of total depletion of the IANA IPv4 address free pool.
(i) Current Phase:
During this phase, AfriNIC will continue allocating IPv4 addresses to
the LIR's using the current allocation policy
http://www.afrinic.net/docs/policies/afpol-v4200407-000.htm. This
phase will continue until a request for IPv4 address space from any
LIR to AfriNIC either cannot be fulfilled with the IPv4 address space
available in the AfriNIC pool (with the exception of the last
allocated /8 address block from IANA) or can be fulfilled but leaving
the AfriNIC IPv4 address pool empty (with the exception of the last
allocated /8 address block from IANA).
This will be the last IPv4 address space request that AfriNIC will
accept from any LIR in the Current Phase, AfriNIC, will declare that
the Exhaustion Phase has begun at this point.
(ii) Exhaustion Phase:
During the exhaustion phase, the following allocation and assignment
policy for the last /8 IPv4 address will be used:
a) Instead of the /22 block (1024) addresses allocated in the current
policy, the new minimum allocation size of /23 (512 addresses) will be
allocated to any LIR that requests for IPv4 resources.
This could be construed to mean that any LIR that requests resources
gets them automatically. You might want to say "any LIR that is
approved for" rather than just "requests".
This is also the maximum allocation size, even though LIRs may request
for more than a /23. No LIR may get more than 4 allocations once the
Exhaustion phase has begun.
b) Together with the v4 allocation, AfriNIC shall allocate an IPv6
address block in compliance with the current IPv6 allocation policy
(http://www.afrinic.net/docs/policies/afpol-v6200407-000.htm) to the
LIR (in case it doesn't have any).
The current allocation and assignment period of 12 months shall be
changed to 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.
Allocation Criteria
---------------------
a) Existing LIR's
At the time of the first IPv4 allocation made during the exhaustion
phase, AfriNIC shall also allocate an IPv6 address block in compliance
with the current IPv6 allocation policy
(http://www.afrinic.net/docs/policies/afpol-v6200407-000.htm) to the
LIR. In order to receive additional IPv4 allocations in the exhaustion
phase, the existing LIR must have used at least 90% of the previous
allocations from the exhaustion phase
This statement that the 90% usage criterion (only) applies to
allocations from the last /8 would seem to create a loophole. If an
organization gets a /23 and uses that up, but has a bunch of free space
in their non-exhaustion-phase allocations, it would seem that they can
get another /23 based solely on the exhaustion-phase usage without
regard to overall usage. I'm not sure if that's what you intended, but
if not, you might want to just have it say something like "90% of all
previous allocations."
b) New LIR's
Each New LIR will receive IPv4 addresses which they can use for
supporting legacy IPv4 services to ensure their full presence on the
IPv4 Internet during the transition to IPv6. The following will apply:
Upon application, a New LIR may receive a maximum of four (4) address
blocks according to the minimum allocation size in effect at time of
allocation in the AfriNIC region. However, the /23 address blocks
shall be issued one at a time.
In order to receive additional IPv4 allocations, the New LIR should
have used at least 90% of the previous allocations from the exhaustion
phase.
New LIRs may apply for and receive this allocation once they meet the
criteria to receive IPv4 address space according to the policy in
effect at the time.
IPv4 Address Space Reserve
---------------------------------
A /16 IPv4 address block will be in reserve out of the last /8 pool.
This /16 IPv4 address block shall be preserved by AfriNIC for some
future uses, as yet unforeseen. The Internet is innovative and we
cannot predict with certainty what might happen. Therefore, it is
prudent to keep this block in reserve, just in case some future
requirement creates a demand for IPv4 addresses.
In the event that the reserved /16 IPv4 address block remains unused
by the time the remaining /8 address space covered by this policy has
been allocated to LIRs, it returns to the pool to be distributed in
compliance with this policy.
It would seem that this clause would defeat the purpose of having the
reservation in the first place. In other words, the /16 wouldn't really
be "reserved" if it is thrown back in the general pool as soon as the
general pool is fully allocated.
-Scott
AfriNIC resources are for the AfriNIC geographical region. None of
these resources can be used outside of the AfriNIC region. All LIR's
requesting resources must have operations in Africa and all of the
allocations shall be used to support the LIR's African Operations.
