As far as I can tell, this is the most current policy for allocation of
IPv6 Blocks to Regional Internet Registries:
There is nothing in it regarding transfering control of portions of these
blocks to a different RIR. In fact, based on the formulas contained
therein, if a RIR were to transfer enough of its space out, it would be
unable to obtain more, as transfered space is not accounted for in the
This policy was ratified in 2006. At that time I doubt there was any
real discussion about allowing transfers of IPv6 between RIRs.
Reading the policy it also does not seem to allow interRIR transfers.
This is the list of currently assigned IPv6 blocks:
Even here, I see nothing granting consent by IANA or otherwise to the
transfer to another RIR of portions of Blocks contained on this list.
Even if ARIN is permitted to allow it, I do not think it to be a good
idea. Right now, without a policy change I can look at that list and know
that 100% of each Block of IPv6 addresses is managed by the RIR listed.
That allows for clean filter lists in IPv6 for those that choose to filter
out abuse routes from other RIR's. Allowing transfers will eliminate that
clean fixed line that currently exists. Also, return and renumbering has
always been part of the policy since the beginning of IPv6 and should be
Also as pointed out by others, if we want to allow interRIR transfers, I
think the global policy needs to be changed to allow it. Otherwise
without global consensus, I think IPv6 transfers should NOT be permitted.

>> I am unaware that IANA/ICANN has EVER voted to permit ARIN or any other RIR to give control of portions of the blocks of IPv6 numbers assigned to ARIN to a different RIR, which is what an inter-RIR transfer of IPv6 resources is.
>> In the IPv6 space there are no legacy addresses. Every Block of IPv6 space was assigned to a specific RIR. That includes every address within that block. Transfers would require a policy at IANA/ICANN to permit these actions. Does such permission exist, and can anyone point me towards it?
>> In any case, even if it is possible, does not mean that it is a good idea. I still maintain that every IPv6 registrant knew the rules of the road when they received their block. Those rules were that they were not transferable between RIR's. If they later choose a different RIR, I say let them renumber.
