Our IPv6 implementation comes with the code to enable this feature,
but by default it is turned off. My proposal is to enable it by
default, and give the user a knob in rc.conf to turn it off.
the only drawback is that forward and reverse dns would not be easily
filled. but anyone who relies on a mac address for dns hacking is
asking for trouble; use dhcpv6 or hard code the host's ip address in
/etc/rc.conf.
DNS in this context is really of least concern, and there are simple
ways around that as Randy states.
I would think that enabling IPv6 Privacy Extensions by default would
have no worse effect on a host in regards to DNS than a similar
situation with IPv4 Auto Configuration.
so i have no problem with the change. thanks for asking.
I also support following the specification by default.
