According to this Wired news article, IANA has begun to "roll out" IPv6. Though it doesn't go into specifics, one assumes this means that the three major IP registries will begin assigning IPv6 addresses. The article mentions another chicken and the egg problem: no IPv6 software (correct me if I'm wrong, but doesn't Linux have IPv6 software?), so there is no need for IPv6 addresses, and vice-versa. It also mentions every traffic light on the planet could have its own IP. Update: 07/16 02:48 by J : Dave Whitinger at LinuxToday sent a link to a mail which clarifies the situation a bit.
