Please enlighten me. 2^24/2^128 x 100 is many orders of magnitude smaller than 2^24/2^32 x 100: gromit% bc scale=50 2^24/2^128*100 .00000000000000000000000000000493038065763132378300 2^24/2^32*100 .39062500000000000000000000000000000000000000000000 There are of course the same number of IPv4 and IPv6 /24s.
