In the ROBIN address allocation described here http://robin-mesh.wik.is/Documentation/Router_Configuring/Advanced_Configuration/Robin_IP_Space I'm curious how collisions are avoided.
 
If you generate IP 5.dd:ee:ff from aa:bb:cc:dd:ee:ff won't you get a collision if you other devices with MACs ending in dd:ee:ff like aa:aa:cc:dd:ee:ff, aa:aa:aa:dd:ee:ff, and so on.
