In some cases, the first octets (1/6ths of the MAC address) still represent the device manufacturer and model, pseudo-randomizing the rest of the address. MAC randomization is a process where software changes the hardware MAC addresses (also known as global MAC addresses) to random and unpredictable strings. What happens when every third device has a random MAC address on a network? Read on to find out! What Is MAC Randomization
This is a cause for concern, as our device intelligence analysts working on CUJO AI Explorer expect over 30% of all mobile devices to use MAC randomization by Feb 2021. Many networking services still rely on MAC addresses for device authentication and security. This means that MAC randomization is quickly becoming the de facto standard in the mobile networking industry. Randomized MAC addresses are meant to obscure mobile devices and increase their privacy, making some networking and authentication solutions obsolete.ĭownload a short MAC randomization whitepaper.Īccording to separate research studies done by Microsoft and Singular, most users do not change default settings on their devices. All iOS 14 devices have randomization enabled by default, as well as Android 10 devices from Google, Samsung, and OnePlus. Media access control (MAC) address randomization is a challenge for most traditional network operators and public Wi-Fi services.
