"The majority of our revenue is booked through the Cisco.com website, and 80% of our technical cases are solved through it," explained Cisco Fellow Mark Townsley. "It was a big commitment by us to run this over IPv6."
Cisco also demonstrated a beta version of its WebEx application that was enabled for IPv6 at the press conference. Townsley said Cisco would ship an IPv6-enabled version of WebEx before Sept. 30, when U.S. federal agencies are required to support IPv6 on their websites to meet an Obama administration mandate.
World IPv6 Launch Day participants reported no major technical glitches or security incidents as they deployed IPv6 across their products, services and content.
Google resolved what it called "minor issues" with its advertising partners as it launched AdSense and content ads with IPv6. Google also said it ran into problems with IPv6 support in its Street View service, and it reported that it was not serving up what are called Quad-A records for IPv6 to a few networks -- primarily in Japan -- that were having problems with IPv6 service.
"Overall, it's been a tremendous success," said Erik Kline, IPv6 software engineer at Google.
Kline noted that Google saw IPv6 adoption increase 150% in the last year, in addition to continued growth with IPv4. "At this rate, 50% of users will have IPv6 in about six years, hopefully sooner as deployment accelerates," he added.
John Brzozowski, distinguished engineer and chief IPv6 architect for Comcast, echoed the view that Comcast saw no major issues with IPv6 on Wednesday. "Call center volumes were at par for this time of the year or below," he said. "It was a seamless event."
Internet pioneer and Google IPv6 evangelist Vint Cerf urged businesses to begin adopting IPv6 immediately.
"There are no more excuses," Cerf said. "You have to be able to run both IPv4 and IPv6 all the time, anytime, because this is not going to be turned off. For any ISP and any edge provider, if you are not capable of running IPv6, you are not being noticed. ... Get going. Get IPv6 running."
