All IP addresses are derived by device's MAC address, if MAC is

format).

Similarly to the case of
MAC-Adress is:
P(r)=1-65536!/(65536^r * (65536-r)!)
Robin uses 3 bytes of the MAC address to choose the IP address of the
mesh interface, not only 2 bytes = 65536 possibilities. This leads to
2^24 = 16777216 different addresses.
