DRAFT: Global Policy for the Allocation of the Remaining IPv4 Address Space

In order to fulfil the requirements of this policy, at the time it is adopted, an identical number of IPv4 allocation units (N units) will be reserved by IANA for each RIR. The number N is defined as: 5. The reserved allocation units will no longer be part of the available space at the IANA pool. The process for the allocation of the remaining IPv4 space is divided in two consecutive 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 cannot be fulfilled with the remaining IPv4 space available at 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 at the 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:

  • Immediately notify the NRO about the activation of the second phase of this policy
  • Proceed to allocate M allocation units to the RIR that submitted the last request for IPv4 address space
  • Proceed to allocate N allocation units to each RIR from the reserved space
