Depending on your local configuration, you may have to change some minor options (e.g add a IPv6 Listen line for Apache), but yeah, in general it's as simple as adding an AAAA record in the DNS. The only troublesome applications I still encounter these days are Munin (monitoring stuff: http://www.munin-monitoring.org/) and anything that's Java based. If its running on a IPv6-enabled host, Java wants to use IPv6 sockets for everything - including IPv4 connections. Most modern operating systems do not allow this; you have to force the use of either IPv4 or IPv6 and disable the other protocol. I had to put these options in a Tomcat startup script: -Djava.net.preferIPv4Stack=false -Djava.net.preferIPv6Addresses=true -- Francois Tigeot
