At work, we’ve been running IPv6 for a while and back home I’ve also got v6 on my DSL connection (not native, though, silverserver implemented that with a tunnel). My root-server also got v6 connectivity via a Tunnel from the nic.at network (easy enough to do if you’re the router-admin :-), but I never used that for serious stuff.
Now that Hetzner finally provides native IPv6 connectivity, I made the necessary changes to the configuration of my server and now this blog is reachable via IPv6, too.
Next task: Get cacti to graph how many visitors use v4 versus v6.
