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

Wait, illegal? Nah, but some MACs are *blocked* by ISPs if they’re tied to fraud or hacking.

Spoofing can trigger security systems tho. Like, my uni WiFi once banned me for a day ‘cause my laptop’s MAC kept changing.

If you’re curious, Wireshark can help sniff out MAC conflicts. But tbh, unless you’re doing shady stuff, you’re probably fine.
