[AfriNIC-rpd] Softlanding Proposal Update

Wed May 13 07:15:36 UTC 2009

Hi all,
This is the most recent Version of the Softlanding Policy Proposal.

I am submitting it for comments ahead of the face-to-face discussion next week; your input will be appreciated.
==================================================================

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 has
already been assigned or allocated IPv4 address space by AfriNIC 

(c) New LIR´s A new LIR is defined as being an organization which has recently
become a member of AfriNIC but has yet to be assigned or allocated any IPv4
address space.

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 is also the maximum allocation size,
even though LIRs may request for more than a /23. No LIR may get more than 4
additional 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 

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.

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.
