Global Policy for post exhaustion IPv4 allocation mechanisms by the IANA
Dear Colleagues, NRO NC is asked by the IANA Staff for a clarification on the reading of this policy, Global Policy for post exhaustion IPv4 allocation mechanisms by the IANA, in regards to "when" the first allocations from the Recovered IPv4 pool can be made. The Council decided to check further with the communities, hence this mail. The policy document (http://www.ripe.net/ripe/docs/ripe-529) states the following: ---- 1.0 Recovered IPv4 Pool …. When one of the RIRs declares it has less than a total of a /9 in its inventory, the Recovered IPv4 pool will be declared active, and IP addresses from the Recovered IPv4 Pool will be allocated as stated in Section 2.0 below. 2.0 Allocation of returned IPv4 address space by the IANA 1. Allocations from the IANA may begin once the pool is declared active. 2. In each "IPv4 allocation period", each RIR will receive a single “IPv4 allocation unit” from the IANA. 3. An "IPv4 allocation period" is defined as a 6-month period following 1 March or 1 September in each year ... ---- While clause 1 seems to be pretty clear, it contains a "may" and clauses 2 and 3 together talk about "allocation periods" and that they are the “6-month period following 1 March or 1 September in each year.” In practice, if the pool is declared active on 1 January and IANA makes the first allocations immediately this would be outside of the allocation period, which begins at the start of March. So mainly the question is about the first allocations from the the Recovered IPv4 pool; a) Should they be made straight away or b) Should IANA wait and make them at the start of the next "IPv4 allocation period," the "6-month period following 1 March or 1 September. In my personal opinion I see no problems with starting straight away (option a above), and then continue the rest in the regularity of the allocation periods as stated in the policy. Would you agree or is your reading towards option b above? Please let us know of your opinions on this list until 23 February 2014. Kind regards Filiz Yilmaz as NRO NC Member from RIPE Region
Hi Filiz, everyone, Looking at your question from the perspective of a RIPE NCC member, I do not think it matters that much (or even at all). I've seen the discussion happening in the ARIN region as well, a few months ago but I do not remember what their decision was. Anyway, regarding both options, here are my comments: option a) - the IANA allocates the Recovered pool straight away Once one of the RIRs reaches less than a /9, the Recovered pool will be divided by 5 and the RIRs will each receive one fifth.. I see no impact on any operations of the RIPE NCC and I would vote for this option. option b) - the IANA waits a few months The RIR that has reached less than a /9 will probably not distribute the whole /9 in the days left before the first 'IPv4 allocation period' starts (1st of March or 1st of September) so even if the IPv4 allocation period starts on the fixed date, the operations of the RIPE NCC will not be impacted (*) * looking at the current policies in ARIN, I am unsure if ARIN could distribute their last /9 within _less than 6 months_ in that case, their operations may be impacted. Therefore, to conclude, I agree with your point, that it would make sense to start right away and not wait for the allocation period to start. cheers, elvis On 05/02/14 19:57, Filiz Yilmaz wrote:

I should probably add that the policy requires the allocations to be "rounded down to the next CIDR (power-of-2) boundary." Consequently, it is likely that the pool would take a number of allocation periods to be fully emptied, depending on whether additional space was returned to it. Kind regards, Leo Vegoda ICANN IANA
I believe option A was the intent behind the global policy. There is no downside to choosing option A, but there could conceivably be a downside to option B (an RIR runs out of space, stops allocations, and then resumes when they get more from IANA). Therefore, I believe that the IANA should proceed based on option A. -Scott P.S. Yes, I am affiliated with ARIN, but also represent a RIPE member. My opinions in this case, though, are based on my evaluation of what is best for the Internet community as a whole, which seems to be the same for everyone involved.

I agree with you, Filiz. Here is how I read the policy. Clause 3 makes no reference to whether the pool has already been declared active; it establishes the beginning of the current and subsequent allocation periods. Whether or not the pool has been activated, we are now (5 Feb 2014) living in an activation period which began on 1 Sep 2013 and looking forward to another which will begin on 1 Mar 2014. In clause 1, the word "once" means "as soon as". Here too, "may" simply indicates that the action is authorized in the circumstances mentioned; no complementary "or may not" option is to be inferred. Clause 4 provides that the allocation unit to be used in the allocation period during which the pool is declared active need not be calculated according to the conditions prevailing at the beginning of this allocation period, but rather according to the conditions current at the moment of activation. I hope this helps. Best regards, Niall O'Reilly
Hi Filiz,
a) Should they be made straight away or b) Should IANA wait and make them at the start of the next "IPv4 allocation period," the "6-month period following 1 March or 1 September.
It makes no practical difference to the RIPE community. This is because even if we were the first region to be the first to hit the low point of a /9 of remaining inventory, which in itself is extremely improbable, there is absolutely no chance of us fully depleting that /9 in during that initial (partial) "IPv4 allocation period", even if that period ended up being 6 months - 1 day. The only real difference is whether or not our 1/5 share of the Recovered IPv4 Pool will formally reside in "IANA storage" or "RIPE NCC storage" in that period. AfriNIC and APNIC are in the same situation. In all likelihood, either ARIN or LACNIC will be the region to first hit the /9 low point, as they plan on allocating normally up until (and beyond) that /9 point. For that reason I suspect those regions prefer option A, as that might prevent them from hitting their own trigger point for implementing their respective austerity policies within the timeframe of that initial (partial) "IPv4 allocation period". If either of those regions do indeed prefer option A, then I think the collegial thing to do would be to let them have it their way. If however ARIN and LACNIC have no preference, I'd say «whichever option makes Leo's job easier». Tore

Your kind thoughts are appreciated. I do not think either option has a greater operational impact than the other. Regards, Leo Vegoda

or 1 September of the previous year, in this case. My reading is that "IPv4 allocation period[s]" run regardless of the status of the pool (active or not).
So mainly the question is about the first allocations from the the Recovered IPv4 pool;
a) Should they be made straight away
At least they "may" (as per 1. above) start immediately. Whether they ought to start immediately, i.e., whether any and all RIRs can derive a right to allocation, is a differrent issue. That becomes more interesting if the state change occurs on 27 Feb rather than 1 Jan. -Peter
Dear Colleagues, It was 23 February 2014 yesterday and so it is time to conclude this thread as announced earlier. From the responses that Peter Koch, Tore Anderson, Niall O’Reilly, Scott Leibrand and Elvis Velea had sent (and considering Leo Vegoda’s post informational), I see there is either support for Option A or people do not see much difference between the options and nobody strongly prefers Option B over A. So my understanding is that there is consensus for Option A from our region, as the reading of Global Policy for post exhaustion IPv4 allocation mechanisms by the IANA: The first allocations from the the Recovered IPv4 pool should be made straight away as soon as the pool is declared active. I will communicate this back to the NRO NC/ASO AC. Thank you very much for your feedback.
