[sig-policy]Proposal for Address Policy SIG
A proposal(P) is submitted below for the forthcoming Address
Policy SIG in Korea on August 21st. It describes IANA policies
for the allocation of IPv4 blocks to RIRs.
Your comments and feedback are appreciated and most welcome.
Best wishes,

Text of proposal:
INTERNET ASSIGNED NUMBERS AUTHORITY (IANA)
POLICIES FOR ALLOCATION OF IPv4 BLOCKS TO REGIONAL INTERNET
REGISTRIES (RIRs)
This document describes the policies governing the
allocation of IPv4 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 these
policies. Such requirements should be specified by
appropriate agreements among the RIRs and ICANN.
1. Allocation Principles
- The IANA will allocate IPv4 address space to the RIRs
in /8 units.
- The IANA will allocate sufficient IPv4 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
Each new RIR shall, at the moment of recognition, be
allocated a new /8 by the IANA. This allocation will be
made regardless of the newly formed RIR's projected
utilization figures and shall be independent of the IPv4
address space that may have been transferred to the new RIR
by the already existing RIRs as part of the formal
transition process.
3. Additional Allocations
A RIR is eligible to receive additional IPv4 address space
from the IANA when either of the following conditions are
met.
- The RIR's AVAILABLE SPACE of IPv4 addresses is less
than 50% of a /8 block.
- The RIR's AVAILABLE SPACE of IPv4 addresses is less
than its established NECESSARY SPACE for the following 9
months.
In either case, IANA shall make a single allocation of a
whole number of /8 blocks, 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 IPv4 addresses of a RIR shall be
determined as follows:
AVAILABLE SPACE = CURRENTLY FREE ADDRESSES +
RESERVATIONS EXPIRING DURING THE FOLLOWING 3 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 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:
A) Calculate NECESSARY SPACE as its total needs for that
period according to its projection and based on the special
facts that justify these needs.
B) 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
When address space is allocated to a RIR, the IANA will send
a detailed announcement to the receiving RIR. The IANA will
also make announcements to all other RIRs, informing them of
the recent allocation. The RIRs will coordinate
announcements to their respective membership lists and any
other lists they deem necessary.
The IANA will make appropriate modifications to the
"Internet Protocol V4 Address Space" page of the IANA
website and may make announcements to its own appropriate
announcement lists. The IANA announcements will be limited
to which address ranges, the time of allocation and to which
Registry they have been allocated.
