22 As an end user of hardened working in a California educational institution I note that my institution doesn't yet have either firewall or router rules stabilized for ipv6 yet and don't expect them for probably another 6 months so whatever is decided it will be off on the servers I administer.
23 Alex makes good points about the lack of expertise in ipv6 firewalls. Having ipv6 on by default would seem to be going against the spirit of the hardened profile since it opens systems to new attack vectors created unwittingly.
