IPv6 - MP3s & presentations This site has PPTs and MP3s from last year's IPv6 Conference. IPv6 is the next generation of Internet IP addressing. It is rapidly becoming necessary to replace the old IPv4 numbering scheme because we are running out of unique numbers with the explosion of devices such as cell phones and smart appliances. Although many of the presentations are technical, be sure to check out Latif Ladid's opening presentation. It is full of gorgeous mockups of future smart devices.
