Comment Adding IPv6 is not difficult (Score 1, Interesting) 406
I upgraded my systems to ipv6 even though I just have IPv4 by signing up for a free tunnel broker service. I recommend SixXS if you are serious, or one of the others if you just want to flirt around with IPv6. Basically, you open a tunnel on one of the machines, it starts radvd which activates ipv6 on every machine on your LAN automagically, and thats all you do. Perhaps edit a config file here or there to turn on ipv6 if its lacking for some reason. The radvd machine broadcasts on your net and provides something like DHCP for all your ipv6 enabled machines which usually just pick it up on the fly with no reboot or anything required.
