### Q: does the card have a MAC address stored in a memory?
A: No. There is no memory where the MAC address is stored. So SPEC boards do not come with a MAC address that is set or programmed by the manufacturer.<br/>
When you use the White Rabbit PTP core, it uses the ID of digital 1-wire thermometer available on the SPEC board to generate unique MAC address for each board. There is a specific [WRPTP FAQ entry about MAC addresses(https://www.ohwr.org/project/wr-cores/wikis/Wrpc-faq#mac-addresses).

Actually, in 2019 the production test system (PTS) has been expanded with the possibility to program a MAC address during production. That address is then stored in the flash eeprom. (April 2020)
