I have some code for doing breakdowns of IPv6 addresses which runs on web logs. It was written for my own consumption, but I've put some instructions on how to use it here: http://www.maths.tcd.ie/~dwmalone/v6classify/instructions.html If anyone is interested in playing with it, I'd be interested to see how it does.
