Draft
Policy Text
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
An RIR is eligible to receive additional IPv6 address space from
the IANA when either of the following conditions are met.
In either case, IANA shall make a single IPv6 allocation, sufficient
to satisfy the established NECESSARY SPACE of the RIR for an 18
month period.
3.1 Calculation of AVAILABLE SPACE
The AVAILABLE SPACE of IPv6 addresses of a RIR shall
be determined as follows:
AVAILABLE SPACE = CURRENTLY
FREE ADDRESSES + RESERVATIONS EXPIRING DURING THE FOLLOWING THREE
MONTHS - FRAGMENTED SPACE
- 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:
NECESSARY SPACE = AVERAGE NUMBER
OF ADDRESSES ALLOCATED MONTHLY DURING THE PAST SIX 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 six 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 needs.
-
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 enclosed.
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
valid.
4. Announcement of IANA allocations
The IANA, the NRO, and the RIRs will make announcements and update
their respective websites regarding an allocation made by the
IANA to an RIR. ICANN and the NRO will establish administrative
procedures to manage this process.
