Are There Illegal MAC Addresses? Can They Cause Issues? or Are There Illegal MAC Addresses? What You

Are there illegal mac addresses? Not *illegal*, but some are reserved for special uses (like broadcast FF:FF:FF:FF:FF:FF).

Spoofing can confuse DHCP servers tho. Had a Pi-hole once that went nuts ‘cause of duplicate MACs.

If you’re testing, ifconfig (Linux/macOS) or ipconfig (Windows) can show your current MAC. Change at your own risk.
