IPv6 Day

Many of my students have insistently questioned when, where, why and how the heck IPv6 is going to be implemented? Well, kids, get ready for some fun, because World IPv6 Day is coming, and it’s the biggest network test I’ve ever dreamed of. And oh ho, most people will have no problem, except say 1,000,000 people trying to access Yahoo, for instance. In other words, there will be glowing coals here and there and hot flames in places. And that’s just tech support!

NetworkWorld has a nice writeup: “Yahoo IPv6 upgrade could shut out 1 million Internet users” at http://www.networkworld.com/news/2011/011911-yahoo-ipv6.html . Even more interesting is the “ugly hack” Yahoo has proposed to deal with the issue: creating a IPv6 DNS “white list” to determine who has valid connections, forcing a fallback to IPv4 if your network isn’t on the list. Hmmmm. More at: http://www.networkworld.com/news/2010/032610-yahoo-dns.html.

In short, get ready for June 8, 2011. See: http://www.networkworld.com/news/2011/011211-world-ipv6-day.html?t51hb&hpg1=mp . Polish up those IPv6 skills! And review v4/v6 tunneling, while you’re at it.
