IPv6, as you’re probably aware by now, is the successor to the current Internet Protocol (IPv4). Developed in the 1990s, it provides more address-space, and has little bonuses like more efficient routing, and small, but measurably improved performance. With IPv4 largely having run out of address-space (earlier this year), and ISPs charging ever-increasing rates for their remaining stocks of IPv4 addresses, there’s a small, but increasing number of systems that are only accessible through IPv6, and a much larger pool that are available through both.

As a major consumer of IPv4 addresses, the question of whether the Lab has any plans to add IPv6 support to Second Life is an interesting question – and one that has been being asked since 2004. However, Lab’s answers take some interpretation at times.

However, being the ingenious sods that we sometimes are – as a species – we managed to cook up a number of “Plan-B”s to buy us more time in which to act.

And then we took that time, we squandered it, and ultimately we lost it.
