On the other hand, when we can deprecate global routing of IPv4, we will see an earth shattering improvement as the current 10:1 prefix to provider ratio (300,000 prefixes for ~30,000 active ASNs) drops to something more like 2:1 in IPv6 due to providers not having to constantly run back to the RIR for additional slow-start allocations.

I suspect as we start seeing the CIDR report for IPv6, we'll see that ASNs are announcing considerably more prefixes than that, in order to localize traffic better. I don't think it'll be 300,000 prefixes, but I'd be willing to bet it'll be more than 100,000--not exactly "earth shattering improvement".

Currently: 3,134 IPv6 ASNs active. Currently: 4,265 IPv6 prefixes. Looks like less than 2:1 to me. That's as close as I think I can get to an IPv6 CIDR report for the moment. Owen
