Today I have setup IPv6 on my home LAN. Now I can connect to websites, which use IPv6 with my unique address from my laptop. Most work was done on a Linux router, on client it was only one command:

sysctl -w net.inet6.ip6.accept_rtadv=1

That’s all. On Linux (router) except for setup tunnel to tunnelbroker it’s only matter of configuring and running radvd. And of course, reconfigure some daemons to listen on IPv6. And now this site can be accessed both by both protocols. Hurray! :-)
