Testimonials on the First Anniversary of World IPv6 Launch

June 2012

“Web-enabled businesses will need to ensure their applications are available over IPv6 in order to keep pace with the Internet’s ever-expanding audience,” said Tom Leighton, Co-Founder & CEO, Akamai. “Akamai is committed to helping our customers with a smooth transition to IPv6 without impacting performance or requiring disruptive changes to their original networking infrastructure. The global breadth of our IPv6 deployment has helped enable a seamless experience for businesses as more content becomes available via IPv6. The Akamai Platform has reached rates of 10 billion requests per day over IPv6, and has seen twice as many Akamai customers with dual-stacked sites since World IPv6 Launch last year.”

Internode founder Simon Hackett says that 10 percent of the Australian ISP’s customers now use IPv6 to access the Internet. “Done right, most customers won’t notice the change to IPv6,” he said.

“Since World IPv6 Launch began on June 6, 2012, the use of IPv6 around the world continues to grow steadily,” said Yoshiharu Shimatani, Senior Vice President of KDDI. “Our measurement shows that IPv6 users of KDDI have doubled and IPv6 traffic has increased about 3 times from last year. We will continue to promote IPv6 deployment in cooperation with world industry leaders of IPv6.”
