This is a good summary of the experiment at a recent IETF to disable IPv4 for one hour to test the issues with using an IPv6-only network infrastructure.The night the IETF turned off IPv4
After working on the new Internet Protocol version 6 (IPv6) for a decade and a half, the Internet Engineering Task Force decided it was time to turn off the old protocol (IPv4 or just IP). So this is what they did for an hour on the network used at the IETF meeting in Philadelphia this week. Network traffic plummeted from some 30Mbps to around 3Mbps as the meeting attendees who had IPv6 enabled could now only get at IPv6-reachable destinations on the Internet. Leslie Daigle, chief Internet technology officer for the Internet Society, who coordinated the IPv4 outage, considers the outage a success.Tweet Posted by mofoghlu at March 18, 2008 3:05 PM | TrackBack
