To state the obvious: there are the same number of /32s in IPv4 space as in IPv6 space. In mathematics, yes, not in actual networks, because of RFC 1715 :-)
I'm not sure the context of the smiley here, but just to be clear: the H ratio is irrelevant. There really are the same number of /32s in IPv4 space as there are in IPv6. Further, as we're talking about PI allocations, there is no hierarchy so the H ratio doesn't apply. The fact that an IPv4 /32 can address 1 interface (or, with NAT, more) and IPv6 can address "a few" more doesn't really matter. Rgds, -drc
