This means that it is possible for two machines in the same network to have the same MAC address.
What happens if someone gets your MAC address?
Your MAC address is your machine’s hardware address. This is mostly only important when an attacker is on the same network as you. At this point an attacker could do deauth attacks or intercept your traffic by posing as the networks router. … You can also change your MAC address as you please.
