“We’ve seen an increase in the past year or so in the percentage of traffic to the DNS root servers carried over IPv6 from somewhere around one percent to between three and four percent,” Kaliski said. “That means of all the queries we receive on a daily basis about three times as many are carried over IPv6 than a year ago and that’s an encouraging sign.”
Growth in IPv6 DNS traffic is a leading indicator of IPv6 adoption. But, while DNS traffic over IPv6 has grown, that doesn’t necessarily translate into a growth of IPv6 traffic for .com and .net top level domains.
