The internet is running out of IP addresses. Engineers at network operators and equipment manufacturers, and test labs such as the UNH-IOL have been implementing IPv6 in equipment and operating systems for years, but much of the Internet's traffic still uses Ipv4. On Wednesday, June 8, 2011, major internet players conducted a test to find out how many internet connections might break if IPv6 were fully implemented today. I spoke with Tim Winters, IPv6 Consortium manager at the UNH-IOL (University of New Hampshire InterOperability laboratory) about the test.T&MW:What was World Day all about?
Winters: The reason for IPv6 World Day was to get more exposure to IPv6. The Internet is currently set up so that most operating systems, when given the choice of using Ipv4 or IPv6, network equipment, browsers, and Web sites will default to IPv6.
