Douglas,
I'll hold off for now on expressing a position on the overall
issue of whether rationing IPv4 space in this manner is an
improvement over current AfriNIC policy. There are good arguments
on both sides, and the question of where to strike the balance
depends a lot on the characteristics of the Internet market in
Africa, which I don't understand all that well, being from outside
the region.
The text looks good overall. A few comments:
It's unclear to me what happens if there remain smaller blocks
outside the last /8 at the point a (large) request cannot be met.
For example, AfriNIC might have a /17, /19, /22, and four /24s
left, when it gets a request for a /16 that it cannot meet. At
that point, the policy says that "During the exhaustion phase, the
following allocation and assignment policy for the last /8 IPv4
address will be used:", but doesn't specify whether addresses
outside the last /8 will also be allocated in this way. Perhaps
it would be best to simply strike "the last /8", leaving something
like "During the exhaustion phase, the following allocation and
assignment policy for IPv4 address will be used". That would also
cover any reclaimed space from outside the last /8.
You might want to specify conditions for exiting the exhaustion
phase someday (when sufficient space has been reclaimed and/or
IPv4 demand has dwindled).
It's unclear to me how many times an existing LIR can come back
for address space in the exhaustion phase. The Summary section's
mention of 4 allocations seems to apply to everyone, but under
Allocation Criteria for Existing LIRs it doesn't mention that like
it does for New LIRs.
It appears that there is no time limit on how frequently a New LIR
can come back for space. You may well have them getting a /23,
using it immediately, and coming right back for another block.
You might want to at least make sure that AfriNIC reserves the
entire contiguous /21 for them, to avoid extra routes in the table.
And some minor nits:
I noticed an apparent contradiction in the definition of 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."
Specifically, "primarily sub-allocates or assigns address space to
'end-users'" seems to conflict with "Their customers are other
ISPs and possibly end-users." It looks like you inherited that
definition from AFPUB-2005-v4-001, but it might be worthwhile to
clarify that while we're at it. :-)
You might want to have the definitions for "Existing LIR" and "New
LIR" simply reference the LIR definition rather than repeating the
"defined as being an organization that assigns address space to
'end-users'" part. So, for example, "An existing LIR is an LIR
that has already been assigned or allocated IPv4 address space by
AfriNIC."
You should probably replace all instances of "LIR's" that are
plural and not possessive with "LIRs".

Hello all,
I am presenting the latest version of the proposal for your
review in preparation for the the face-to-face meeting that is a
couple of weeks away.
Your input in required
==================================================================
Your Name: Douglas Onyango
Your Organisation: Delta IT Solutions
Policy Afected: AFPUB-2005-v4-001
Date: 27-11-09
Proposal: IPv4 Soft Landing Policy
Incentive
------------
In order to ensure a smooth 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 this Global
Policy
The purpose of this document is to ensure that this last block is
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, and
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 /24 (256
addresses) will be allocated to any LIR that qualifies for IPv4
resources - /23 (512) will be the maximum allocation size
possible and even though LIRs may request for more than this,
LIRs will not be able to get more a /23 in a single allocation
- they also will not get more than 4 allocations once the
Exhaustion phase has began.
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
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 allocation size in effect at the
time of allocation in the AfriNIC region. However, the 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 /12 IPv4 address block will be in reserve out of the last /8
pool. This /12 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.
When AfriNIC can no longer meet any more requests for address
space from the last /8 pool because the pool is either empty or
has no more contiguous blocks, the board will based on the demand
and other factors at the time exercise the prerogative to
replenish the exhaustion pool from the reserve pool in a manner
that is in the best interest of the community.
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.
