I was amazed. Ipv6 is fully supported in Centos 6. Even the firewall tools (system-config-firewall and lokkit) configure ipv4 and ipv6 automatically. I also noticed that my RackSpace server has an ipv6 address, so I'm guessing they support it as well. It looks like I'll be using ipv6 sooner than I thought! Thanks for the presentation, Mike. c
