Hi again Oliver,   
      
   Setting the MAC and setting register $001a to $06 works perfectly with   
   IP65. However with Contiki I am still getting :11:11:11.  I tested with   
   WEBBROWS.SYSTEM.   
      
   I checked the version of Contiki I am running and it is the release from   
   2019-05-08. I am not sure if there is a more recent one -- if so, I wasn't   
   able to find it.   
      
   Is there a newer build I can grab from somewhere?   
      
   All the best,   
   Bobbi
