Wow, nice lecture... :-)

Thanks a lot... I should open more tickets here, very instructive... ;-)

Seriously now, I changed my LEDE router to "stateful only", which to my understanding means it only hands out IPv6 addresses via DHCPv6 as you described above. Still my Mac immediately got an IPv6 address (/64!) after I pulled out and reconnected my Ethernet cable.

Anyway, I do have Linux machines in my LAN, so I could do some further testing. I tried to find out how to "forcibly request a prefix ['of given length', I suppose?!]", but I couldn't.

Can you please share an example how to do it in Linux? (I use Debian and Ubuntu...)

Thanks!
