Roques,
- IANA to distribute a single /8 to each RIR when the IANA free
pool hits 5 /8s. This date is defined as 'IANA Exhaustion Date'.
Seems fine, although just to be explicit:
Suppose there are 6 /8s remaining in the free pool. An RIR comes to
IANA and indicates they want another allocation. Current practice is
to allocate 2 /8s (if justified). IANA allocates the 2 /8s, leaving
4 /8s. The obvious approach would be to allocate the remaining 4 /8s
to the other 4 RIRs. Is that the intent?
We though a lot about this issue when we came out with our proposal,
because it needs to be crystal clear for IANA. We first discussed using
some integer value formulas and finally came out with the reservation
idea. We did not received any comment about problems in our text and I
am not very sure why you rather propose a different text than supporting
the existing one with a different value for the last allocation (the
only main difference).
If you are refering to the formula (R * N <(X-A)) I'm personally quite
happy to follow your formula for this part, but I still have to talk to
the others as this is a group proposal.
I'm not sure if I follow your idea on reservation though. Are you
refering to the phrase below?
------
In order to fulfill the requirements of this policy, at the time it is
adopted, an identical number of IPv4 allocation units (N units) will be
reserved by IANA for each RIR.
