Hello,
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.
