In my capacity as a member of the ASO Address Council appointed
by the AfriNIC Board, and in terms of my responsibilities as
recorded in clause 2 of attachment A of the ICANN ASO Mou
(, I hereby submit the
appended proposal in terms of the AfriNIC policy development process
(, and request that this proposal be
placed on the agenda of the next AfriNIC open policy meeting.

This is a proposed global policy, which is intended to
be handled in terms of attachment A of the ICANN ASO MoU

AfriNIC Proposed policy:
        Allocation of IPv6 Address Space by the Internet Assigned       
        Numbers Authority (IANA) to Regional Internet Registries 
Submitted by: A P Barrett
Date: 1 August 2005

Related policies and proposals in other regions:

Note: The wording below is identical to the wording of ARIN policy
        2004-8.  Some of the other RIRs are considering proposals with
        similar but not identical wording.

Policy statement:

This document describes the policy governing the allocation of IPv6     
address space from the IANA to the Regional Internet Registries         
(RIRs).  This document does not stipulate performance requirements in    
the provision of services by IANA to an RIR in accordance with this     
policy.  Such requirements will be specified by appropriate agreements   
between ICANN and the NRO.                                              

1. Allocation Principles 

The unit of IPv6 allocation (and therefore the minimum IPv6 allocation) 
from IANA to an RIR is a /12                                            

The IANA will allocate sufficient IPv6 address space to the RIRs to     
support their registration needs for at least an 18 month period.       

The IANA will allow for the RIRs to apply their own respective chosen   
allocation and reservation strategies in order to ensure the efficiency 
and efficacy of their work.                                             

2. Initial Allocations 

On inception of this policy, each current RIR with less than a /12      
unallocated address space, shall receive an IPv6 allocation from IANA   

Any new RIR shall, on recognition by ICANN receive an IPv6 allocation   
from the IANA                                                           

3. Additional Allocations 

A RIR is eligible to receive additional IPv6 address space from the     
IANA when either of the following conditions are met.                   

The RIR's AVAILABLE SPACE of IPv6 addresses is less than 50% of a /12.

The RIR's AVAILABLE SPACE of IPv6 addresses is less than its            
established NECESSARY SPACE for the following 9 months.                 

In either case, IANA shall make a single IPv6 allocation, sufficient    
to satisfy the established NECESSARY SPACE of the RIR for an 18 month   

3.1 Calculation of AVAILABLE SPACE 

The AVAILABLE SPACE of IPv6 addresses of a RIR shall be determined as


FRAGMENTED SPACE is determined as the total amount of available blocks  
smaller than the RIR's minimum allocation size within the RIR's         
currently available stock.                                              

3.2 Calculation of NECESSARY SPACE 

If the applying Regional Internet Registry does not establish any       
special needs for the period concerned, NECESSARY SPACE shall be        
determined as follows:                                                  

THE PAST 6 MONTHS * LENGTH OF PERIOD IN MONTHS                          

If the applying RIR anticipates that due to certain special needs the   
rate of allocation for the period concerned will be different from the  
previous 6 months, it may determine its NECESSARY SPACE as follows:     

Calculate NECESSARY SPACE as its total needs for that period according  
to its projection and based on the special facts that justify these     

Submit a clear and detailed justification of the above mentioned        
projection (Item A).                                                    

If the justification is based on the allocation tendency prepared by    
the Regional Internet Registry, data explaining said tendency must be   

If the justification is based on the application of one or more of      
the Regional Internet Registry's new allocation policies, an impact     
analysis of the new policy/policies must be enclosed.                   

If the justification is based on external factors such as new           
infrastructure, new services within the region, technological advances  
or legal issues, the corresponding analysis must be enclosed together   
with references to information sources that will allow verification of  
the data.                                                               

If IANA does not have elements that clearly question the Regional       
Internet Registry's projection, the special needs projected for the     
following 18 months, indicated in Item A above, shall be considered     

4. Announcement of IANA Allocations 

The IANA, the NRO, and the RIRs will make announcements and update      
their respective web sites regarding an allocation made by the IANA to  
an RIR. ICANN and the NRO will establish administrative procedures to   
manage this process.
