I'm running nearly all my services in dual stack mode, as my dedicated server provider hetzner.de offers native IPv6 for quite some time. Basic IPv6 is not that hard but when it comes to things like iptables you have to take care: Most iptables frontends can only handle IPv4 or do that as default. You have to take care of the IPv6 yourself or activate it. E.g. Phusion Passenger/nginx installer did not activate the IPv6 module on compile time (not sure if this is still the case) Also I've disabled all RA/autodiscovery functionality which is probably not a good idea to run/listen to on the server side anyway. I can recommend a nice directory of IPv6 ready sites: http://sixy.ch/ http://sixy.ch/

looks like rails.io currently has some ipv6 problems: Fast:~ schmidp$ host rails.io rails.io has address 188.40.182.49 rails.io has IPv6 address 2a01:4f8:100:9461::49 rails.io mail is handled by 10 mail100.fks.de.moriz.net.
