Proposal Version: 1.0
Submission Date: Oct-30-2007
Proposal type: new
Policy term: permanent
Policy summary:
This policy will establish a process for RIR-to-RIR redistribution
of the
tail-end of the IPv4 pool, taking effect after the IANA Reserve is
exhausted. Each redistribution Allocation will be triggered by the
recipient
RIR depleting its reserve to a 30 day supply, and will result in up
to a 3
month supply being transferred from the RIR with the longest
remaining time
before it exhausts its own pool.
Policy statement:
At the point when any given RIR is within 30 days of depleting its
remaining
IPv4 pool, a survey will be taken of the other 4 to determine the
remaining
time before each of them exhausts their pool (including both member
use and
recent redistribution allocations to other RIRs). The one with the
longest
window before exhausting its pool will be designated as the source
RIR. The
recipient RIR will follow procedures for an LIR in the source RIR
region to
request a block that is expected to be sufficient for up to 3
months, but is
no larger than 1/8th of the source RIR's remaining pool. At the
point where
no RIR can supply a block that is less than 1/8th of their
remaining pool
that will sustain the recipient RIR for 30 days, the recipient RIR
will
collect its requests each week, and forward those individual
requests to the
source RIR designated that week.
Rationale:
This policy will establish a mechanism for the Allocation of IPv4
address
blocks between RIR's, but will not go into effect until the IANA
pool has
been depleted.
It is really bizarre to watch the maneuvering as the global RIR
community
grapples with 'fairness' of distributing the last few IANA Reserve /8
blocks. On one level this just appears to be petty sibling rivalry, as
people are bickering over who gets the last cookie and whimpering
about
'fairness'. At the same time, each RIR is chartered to look after the
interests of its membership so it is to be expected that they will
each want
to get as much as possible to meet the needs of their respective
membership.
Existing practice requires RIR's to acquire blocks from IANA, which
leads to
the current round of nonsense about optimal distribution of the
remaining
pool based on elaborate mathematical models.
This globally submitted policy proposal attempts to resolve the
issue by
shifting to an RIR-to-RIR Allocation model after the IANA pool is
depleted.
This policy would effectively result in each RIR becoming a virtual
LIR
member of all of the other RIR's for the sole purpose of managing the
tail-end of the IPv4 pool.
Timetable for implementation: Before 1/1/2009
