On slide 4 in Tim's material, we can see only /32 and /35. But if my
understanding is correct, some ISPs already obtains shorter (larger)
prefix than /32.

I can find the number /27 in the slide of IPv6 routing table only. Is
this one large prefix assigned to one big ISP? Such things are not
clear to me.

I would like to know how many /32, /31, /30, /29, etc are already
assigned from APNIC report.

What I referred to is Paul's "IPv6 allocations to IPv4 networks" in
Policy SIG. Am I confused? It would be appreciated if you kindly
clarify things relating to the HD ratio.
