All the MAC layer operations will happen with the random MAC. ![]() If this feature is enabled, the device will not be shown its reals MAC in the air. MAC Randomization is a technique that protects WiFi enabled devices being tracked. I have used wpa_supplicant to test the scenarios and the post refers to Random MAC implementation in WPA supplicant. Locally Administered MAC Addresses There are 4 ranges of Locally Administered Address Ranges that can be used If any device is generating the random MAC Address then it should set the locally administered bit. Now we will learn about this feature and we will see the sniffer captures for different MAC Randomization settings.īefore we learn about the WiFi MAC Randomization, we will first check the locally administered MAC Addresses range that devices will be generating as a random MAC Addresses. First 3 bytes are organization OUI and it identifies the manufacturer of the device, and next 3 bytes uniquely identifies the device and it is NIC Specific.
