Hey folks, Where's a good place to learn about IPv6? I've *mostly* got my head around IPv4 these days, and my ISP still only has an unsupported 6rd gateway which I've tried with momentary success on my router. I understand that the address space is 128 bits vs 32, that successive colons mean 0000 between them, that devices can have "local" and "global" scoped addresses, and it's *supposed* to do away with NAT... but that's about as far as I've gotten :) A server I lease overseas has an IPv6 address block assigned to it, and I'm struggling to figure out how I'm supposed to assign a reverse DNS to it, so Google and friends don't flag it for the MTA not having a reverse lookup (for now, I just lock it to IPv4)... I figured I might as well learn more about how it works, different to IPv4.. Any practical pointers?
