YouTube, Netflix Dominate IPv6 Traffic

5:40 PM -- Comcast Corp. (Nasdaq: CMCSA, CMCSK) is hungry for more IPv6 traffic, but it certainly can't pin any of the blame on YouTube Inc. and Netflix Inc. (Nasdaq: NFLX). (See Comcast: More IPv6 Traffic Please .)

They're doing their part as, together, they represent almost all of the native IPv6 traffic in the early going, according to some preliminary data released by Sandvine Inc. Thursday, the day after World IPv6 Launch Day. (See IPv6 Launch Day: Should Milestones Be Boring?)

Sandvine notes that there was a slight uptick in IPv6 traffic on June 6, just as Comcast witnessed, but points out that the big spike occurred in late May, when Netflix and Facebook enabled their sites. YouTube's had IPv6 enabled for much longer, so it's been the driving force in the category for a while:

But even with Facebook 's recent entry, YouTube (57 percent of distribution) and Netflix (32.56 percent) rule the native IPv6 world. Here's how Sandvine data sees the IPv4 and IPv6 domains stacking up:

Sandvine also noticed that it appears as though Netflix may have created its own IPv6-specific domain, rather than operating a single domain with IPv6 and IPv4 records, meaning (tsk, tsk...) Netflix "might not be in full compliance with the spirit" of World IPv6 Launch Day.

But we won't hammer them too hard. At least Netflix is on the board, while IPv6 is hardly on the radar for most of the Web. That may change, though, as Vint Cerf and the gang try to nag everyone else to get with the program posthaste. (See IPv6 Hoopla Not Over Yet.)

But you can see why Comcast's John Brzozowski wouldn't mind seeing more v6 traffic. Despite the contributions of Netflix and YouTube, there's not much to speak of yet. The sad number here is that just a bit more than .4% of downstream bandwidth on the big day was native IPv6 in N. America, according to Sandvine, which did pledge to dive a bit deeper into the data and post some additional results soon. JB

re: YouTube, Netflix Dominate IPv6 Traffic

A few years ago, there was a study sponsored by a US government agency (perhaps NIST) on transitioning to IPv6. A key finding in the study on why users might be slow in moving to v6 was the cost of retraining IT staff. If that is correct, then hesitation on the part of businesses to adopt v6 is, in a way, understandable.
