No, they call it dynamic, because they do not guarantee that the /56 prefix 
will never change. Since November 2017 it has only changed once. That was after 
a three hour unscheduled power down. Short power interuptions do not seem to 
cause a change.

Even so, all THEY set is the prefix. Within the /64, I can either use SLAAC or 
configure it manually. The latter I did for the ::f1d0:2:280:5555 part.


Cheers, Michiel
