IPv6 address generation.


I have a question concerning address generation. I have been working on an old copy of RIOT system (December 2015) and every node generated its own unique local unicast IPv6 address. I suppose this address was generated thanks to CPUID which was unique for every processor. I made an update recently (April 2016) and all nodes has the same address.

May someone explain me how the address is generated? I would be grateful for any help.

Hi, The addresses should still be based on the CPU ID, so it would be great if you would tell us what hardware you are using (both MCU and radio).
