Oh, good point. Yes, it seems to be enabled-by-default, and since the
operating system on the client system does not *know* that it's 6to4
(for the client, it's just "IPv6 that someone announced a RA for on the
local LAN"), it can't properly (de-)prioritize it...
The Airport Extreme seems to do it automatically if you give it a public IP
- I have one, it interfered with my native IPv6, so I turned it off. But
it was on-by-default.
