Using your numbers, if one looks at the Address Table ratio of 600 to
30, thats 20:1
Using your ASN count ratio - its now 60:20 or 3:1.
a 3:1 ratio seems a lot worse than a 20:1 ratio
I'd still like to see what the real ratios are though.
I did find at:-
"At 70%, the percentage of IPv4 address space announced by ASNs that
also announce IPv6 is in stark contrast with the fact that only around
1.5% of end users can actually use the IPv6 Internet, according to

With that - I agree,
