Policy Affected: The current on-demand
global policy for the distribution of IPv4 address space to the
Regional Internet Registry (RIR) system.
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.
Proposal:
--------------
Policy Statement:
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 (/8s)
will be allocated from IANA to each RIR, replacing the current IPv4
allocation policy.
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 initiated.
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
space.
Rational:
---------------
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 each RIR.
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.
