Uh, when did *this* happen? I see privacy addresses change "every few hours" and "on reconnect", but not for every single connect (tested from MacOS and Linux, curling http://v6only.v6.de/ip.html 10 times in sequence, no change in IPv6 address displayed). If this happens on mobile phones (which are known to do funny things), the point is a bit moot for the discussion here... Gert Doering -- NetMaster -- have you enabled IPv6 on something today...?
