The long steady slog toward IPv6 continues. The Internet Society reports that Comcast has hit the 30 percent mark for IPv6 deployment, AT&T is now past the 20 percent mark and Time Warner Cable crossed over 10 percent threshold. Last month, Verizon Wireless was the first operator in North America to reach 50 percent (it is at 53.5 percent this month).

Comcast’s entire broadband network is now fully deployed to support IPv6 dual stack connectivity, reported Comcast Cable Fellow and Chief IPv6 Architect John Brzozowski in a recent blog post.

IPv4 resources continue to dwindle, Brzozowski reminded, as next generation network technologies, like IPv6 Segment Routing and Service Function Chaining, begin to take shape.

He said Comcast’s IPv6 penetration is expected to reach nearly 50 percent by the end of 2014.

“Beyond that, our plans include support for additional residential devices, as well as the launch of IPv6 capability for our Business Internet customers.  In addition, Comcast continues to leverage IPv6 across the entire product and service portfolio, with IPv6 only support planned for both the Xfinity X1 platform and Xfinity Voice, with trials slated for later this year.

The company also recently launched IPv6 support for several NBCUniversal digital properties, including nbc.comnbcsports.com and universalstudios.com.

Many content companies are making content IPv6-enabled, but Google has notably given IPv6 a significant push by making YouTube streaming dual-stack enabled by default.

Brzozowski said companies such as Google have helped Comcast hit a traffic watermark of 1Tb/s of Internet facing, native IPv6 traffic.
