MAC ID, real UUID?
Posted: Thu Jul 02, 2020 5:05 pm
Hey esp-team
Maybe you can help me:
I want to have an UUID for each esp. Therefore I think the MAC address (6 byte = 54 bit = 2^54 possiblites) is necessary.
But how unique is this MAC address really?
In some cases of other vendors the MAC address is splitted in vendor id and address id. Then this 2^54 possiblites would be much fewer.
The question: Is the MAC address a real random uuid number or are there any dependencies which makes this possiblites fewer.
Thank you very much
