World IPv6 Day

June 8, 2011 (this Wednesday) is World IPv6 Day, a day that several major organizations will offer content over IPv6 during a 24-hour time period. As stated on the ISOC website, “the goal of the test flight day is to motivate organizations across the industry – Internet service providers, hardware makers, operating system vendors and web companies – to prepare their services for IPv6 to ensure a successful transition as IPv4 addresses run out.”

Organizations who are taking part in World IPv6 Day include Google, Facebook, Yahoo, Akamai, Limelight Networks, CISCO, Comcast, and many more. You can find the entire list of stated participants here,

wolfSSL has support for IPv6 as well! wolfSSL was designed as IP neutral, and will work with both IPv4 and IPv6. The test applications included in the wolfSSL download currently default to using IPv4 (to apply to a broader number of systems). In order to change the test applications to use IPv6, use the –enable-ipv6 option while building the wolfSSL embedded SSL library.
