I’m not making any suggestions about the order in which ARIN issues AS Numbers.

I’m simply suggesting that we stop treating AS Numbers as anything other than a single
collective pool of 32 bit integers from which ARIN issues them.

High to low, low to high, or random order is fine with me. However, the community adopted
a policy that said ARIN is to treat them as a single pool of 32-bit identifiers and so long
as we continue to ask questions like this in the application process, it’s pretty clear that
policy isn’t being followed.
