Below is updated Policy text will the following changes.
An Existing LIR is a LIR that assigns address
space to 'end-users' and has
already been assigned or allocated
IPv4 address space by AfriNIC.
A New LIR is a LIR that assigns address space to 'end-users' and is
member of AfriNIC that has not been assigned or allocated any
space prior to the Exhaustion phase.
An End User is an organization that receives assignments of IP
exclusively for use in its operational networks.
above paragraph says that the allocation size used is the one in effect
at the time of the application. That's the numbers mentioned in
> 4) AfriNIC resources are for the AfriNIC
geographical region. For each allocation or assignment made during the
Exhaustion Phase, no more than 10% of these resources may be used
outside of the AfriNIC region, and any use outside the AfriNIC region
shall be solely in support of connectivity back to the AfriNIC region.

In order to ensure a smooth transition to IPv6, AfriNIC's pool should be managed to provide members with routable blocks after the IPv4 pool is depleted, in order to maintain and deploy IPv4 networks while deploying IPv6 networks during a gradual transition to IPv6. This document proposes a strategy for allocation and maintenance of AfriNIC's final /8 block of IPv4 from IANA.
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
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
Policy Documents to be affected:
(a) IPv4 Allocation Policy
(b) Proposal to Change the Allocation & Assignment Period
to 12 months
(a) Local Internet Registry (LIR)
A Local Internet Registry (LIR) is an Internet Registry
(IR) that receives allocations from an RIR and assigns
address space to customers who use its services. LIRs are
generally ISPs and their customers are end-users and
possibly other ISPs. LIRs must be members of an RIR like
AfriNIC; which serves the Africa Region and part of the
Indian Ocean (Comoros, Madagascar, Mauritius, and
(b) Existing LIR's
An Existing LIR is a LIR that assigns address space to
'end-users' and has already been assigned or allocated IPv4
address space by AfriNIC.
(c) New LIR
A New LIR, is a LIR that assigns address space to
'end-users' and is a member of AfriNIC but has not been
assigned or allocated any IPv4 address space prior to the
(d) End User
An End User is an organization that receives assignments of IP addresses
exclusively for use in its operational networks
(e) Final /8 block of IPv4 address space, or "Final /8".
The Final /8 block of IPv4 address space, or "Final /8", is
the /8 block of IPv4 address space that will be allocated by
the IANA to AfriNIC in terms of section 2.2 C of the Global
Policy for the Allocation of the Remaining IPv4 Address Space
at the time of exhaustion of the IANA pool of IPv4 address space.
AfriNIC's version of the Global Policy for the Allocation of the
Remaining IPv4 Address Space is also known as AFPUB-2009-v4-001
This proposal describes how AfriNIC shall assign, allocate, and manage
IPv4 resources during an "Exhaustion Phase" which begins when AfriNIC
first needs to assign or allocate IP addresses from the Final /8 block
of IPv4 address space.
(i) Current Phase:
The "Current Phase" is the status quo at the time of adoption of
this policy. During this phase, AfriNIC will continue allocating
or assigning IPv4 addresses to LIRs and End Users using the current
policies, including AFPUB-2005-v4-001
any future amended versions of such policies.
The current phase will continue until an otherwise-valid request for
IPv4 address space from any LIR or end user to AfriNIC either (a) cannot
be fulfilled with the IPv4 address space available in the AfriNIC pool
(with the exception of the Last /8), or (b) can be fulfilled, but would
leave the AfriNIC IPv4 address pool empty (with the exception of the
The request that results in either of the above conditions being
fulfilled will be the last IPv4 address space request that AfriNIC
will accept from any LIR or End User in the Current Phase. If the
request can be processed in terms of the Current Phase policies,
then it will be so processed; otherwise, it will be processed in
terms of Exhaustion Phase policies.
AfriNIC will publically announce that the Exhaustion Phase has begun
at this point.
(ii) 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 at all times after the transition to
the Exhaustion Phase, regardless of the amount of IPv4 address space
available to AfriNIC.
a) The minimum allocation or assignment size for IPv4 will be
a /24 block (256 addresses). The maximum alocation or assignment
size will be a /23 block (512 addresses). No LIR or End User
will receive more than 4 allocations or assignments during the
b) If any LIR or End User requesting IPv4 address space during the
Exhaustion Phase does not already have IPv6 address space, then AfriNIC
shall allocate or assign an IPv6 address block in compliance with the
IPv6 allocation or assignment policies in effect at the time.
c) 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.
1) In order to receive IPv4 allocations or assignments during the
Exhaustion Phase, the LIR or End User must have used at least 90% of all
previous allocations or assignments (including those made during both
the Current Phase and the Exhaustion Phase). In the case of new LIRs or
End Users with no previous allocations or asignments, this requirement
does not apply to their first allocation or assignment request.
2) An LIR or End User may receive a maximum of four (4) address blocks
during the Exhaustion Phase, according to the allocation size in effect
at the time of the application. The four address blocks shall be issued
one at a time, in response to separate applications.
3) If an LIR or End User does not already have IPv6 address space, then
AfriNIC shall allocate or assign an IPv6 address block in compliance
with the IPv6 allocation or assignment policies in effect at the time of
the LIR or End User's first request for IPv4 address space during the
4) AfriNIC resources are for the AfriNIC geographical region.
For each allocation or assignment made during the Exhaustion Phase,
no more than 10% of these resources may be used outside of
the AfriNIC region, and any use outside the AfriNIC region
shall be solely in support of connectivity back to
the AfriNIC region.
IPv4 Address Space Reserve
A /12 IPv4 address block will be in reserve out of the Last
/8. 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.
