Arbor Networks has released the largest analysis to date of IPv6 traffic on the Internet…and finds there’s almost none. During July 2008, there was about 600 Mbps of interdomain IPv6 traffic measured on the Internet, compared to four Tbps of old-school IPv4 Internet traffic. Put another way, IPv6 traffic accounted for just 0.0026 percent of total Internet traffic for the month.
"It is now clear the original optimistic IPv6 deployment plans have failed," said Arbor Networks’ chief scientist Craig Labovitz, in a statement. "Based on our analysis, at the current rate of adoption, we are a decade or more away from pervasive adoption of dual stack support for IPv6."
