I support this proposal
Name: Hytham Zakaria EL Nakhal
Organisation: National Telecom Regulatory Authority, Egypt
Date: 07 July 2007
Status: Open for discussion
Authors: Roque Gagliano (ANTEL), Francisco Obispo (CENIT), Hytham EL
Nakhal (MCIT), Didier Allain Kla (ISOC Cote d'Ivoire)
Policy Affected: The current on-demand global policy for the
distribution of IPv4 address space to the Regional Internet Registry
Incentive: In order to assure the equal distribution of the IPv4 address
space across RIR regions, this policy proposal describes a process for
the allocation of the remaining IPv4 space from
IANA to the existing RIRs
Policy Proposal Name: Global Policy for the Allocation of the Remaining
IPv4 Address Space.
This policy describes the process for the allocation of the remaining
IPv4 space from IANA to RIRs. When a minimum amount of
available space is reached, an identical number of IPv4 allocation units
will be allocated from IANA to each RIR, replacing the current IPv4
In order to fulfill the requirements of this policy, at the time of its
adoption, an identical number of IPv4 allocation units (N) will be
reserved by IANA for each RIR. The number N is
defined as 5. The reserved units will no longer be part of the available
space at IANA pool.
The process for the allocation of the remaining IPv4 space is divided in
two consecutives phases:
1. Existing Policy Phase:
During this phase IANA will continue allocating IPv4 addresses to the
RIRs using the existing allocation policy. This phase will continue
until a request for IPv4 address space from any RIR to IANA can not be
fulfilled with the remaining IPv4 space available in the IANA pool.
This will be the last IPv4 address space request that IANA will accept
from any RIR. At this point the next phase of the process will be
2. Exhaustion Phase:
IANA will automatically allocate the reserved IPv4 allocation units to
each RIR (N units to each one) and respond to the last request with the
remaining available allocation units in IANA pool (M units).
2.1. Size of the final IPv4 allocations:
During this phase IANA will automatically allocate N allocation units to
each RIR from the reserved space defined in this policy. IANA will also
allocate M allocation units to the RIR that submitted the last request
for IPv4 addresses.
2.2. Allocation of the remaining IPv4 Address space:
After the completion of the evaluation of the final request for IPv4
addresses, IANA must:
A) Immediately notify the NRO about the activation of the second phase
of this policy.
B) Proceed to allocate M allocation units to the RIR that submitted the
last request for IPv4 address space.
C) Proceed to allocate N allocation units to each RIR from the reserved
The IANA pool of allocation units of IPv4 addresses (/8s) is decreasing
rapidly. A new policy is proposed to replace the current "on demand"
policy in order to bring certainty on how the remaining space will be
allocated. This policy eliminates the pressure on the remaining central
pool of addresses by allocating equal amount of allocation units (N) to
RIR may be studying slow-landing policies or the possibility to reserve
specific address spaces for "critical infrastructure" or new companies
in order to comply with anti-trust regulations in its region. This
policy allows each RIR to adopt those policies through its PDP, which is
simpler than a global policy discussion process. Each RIR will have the
exact information on the amount of address spaces that they will be
receiving as a last allocation from the IANA.
The policy is written in such a way that the discussion could be split
in two sections: first do we agree on the concept of the policy and
second what is the appropriate value for the last allocation units N.
Thanks and best regards
