IPv6 Traffic Keeps Growing, Cable ISPs Say
Speaking at an IPv6 Summit, held as part of The Cable Show, John Brzozowski, chief IPv6 architect for Comcast Corp. (Nasdaq: CMCSA, CMCSK), and Lee Howard, director of network technology for Time Warner Cable Inc. (NYSE: TWC), both say their companies saw second-day spikes of IPv6 traffic after major websites such as Google had turned off the IPv6 connections they had set up for the June 8 global test.

Phil Roberts, technology program manager for the Internet Society (ISOC) , says that its tracking shows that many websites that created a front-door approach for IPv6 on World IPv6 Day either had determined in advance that they would leave the connections open or were satisfied enough with how the test went that they saw no reason to turn off the connectivity.
"Everyone is on a different trajectory," Roberts acknowledges, "but as of yesterday, about two-thirds of the websites that turned on IPv6 for World Day have left it on, and that includes some big ones globally."
"We saw a six-times increase in IPv6 traffic during World IPv6 Day, and our traffic levels not only went up but we saw them stay at a higher rate," says Brzozowski. "That is what we are looking for, a sustained uptick in traffic."
Time Warner Cable continues to see a high level of IPv6 traffic, Howard says, leading to the "new normal," as he called it. While there were some unexplained anomalies to the massive global testing event, trouble calls were few and far between.
"We had more wrong number calls than real trouble calls," Howard says.
