has the current numbers, and they say the ratio "ASes with IPv6 to ASes
with IPv4" is about 0.163 now (=16%).  This is just AS numbers, not
correlating amount of announced space - so what Emile has is "most large
providers with lots of IPv4 space have IPv6 now", while my numbers seem
to suggest that "too many leaf nodes are still lagging behind".
