Just a quick note to let you know that www.nowhere.dk is now accessible through IPv6
$ host -t AAAA www.nowhere.dk www.nowhere.dk CNAME coredump.nowhere.dk coredump.nowhere.dk AAAA 2001:2010:0:2:0:0:0:DEAD
The only thing I had to do was to enable IPv6 in Lighttpd, enable IPv6 in ufw (done in
/etc/default/ufw) and then re-add any rules to ufw that affect IPv6 (like web and ssh). The last part is crucial and not very well documented.
