When it became clear that 32-bit IP addresses just wouldn't cut it for a growing Internet, the Internet Engineering Task Force did what its name suggests and created a new version of IP. IPv6 has so many addresses that it will resist our best efforts to waste all of them for many decades, if not centuries. Of course to benefit from the larger IPv6 address space, it's necessary to actually migrate from the existing IPv4 to the new IPv6. That part has been sorely lacking in the 15 or so years since the first IPv6 specifications were published. The good people over at Arbor Networks did a study in 2007 that showed surprisingly little uptake of the new protocol. And remember, that surprise was on top of the already set-in realization that IPv6 wasn't taking the world by storm in the first place. And now, as IPv4 addresses have run out in part of the world already, Arbor has repeated its study.
The result? A reduction in tunneled IPv6 traffic during the study period.
