MAC ID, real UUID?

[AlexESP32]

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

The MAC is globally unique and not random, as it's given out sequentially to each ESP32/ESP8266/.... Espressif (and on a higher level, the IANA and the companies that bought address blocks from them) make sure that there are no devices with the same MAC anywhere in the world.

All right. Thank you
