Does Android randomize MAC address?
Starting in Android 8.0, Android devices use randomized MAC addresses when probing for new networks while not currently associated with a network. In Android 9, you can enable a developer option (it’s disabled by default) to cause the device to use a randomized MAC address when connecting to a Wi-Fi network.

Should I use randomized Mac or phone Mac?
The idea is to increase your privacy by making it impossible to track you. This is not a perfect solution and there are ways around MAC address randomization that still enables tracking if someone really wants to track you. However, like all security methods, it helps and it is certainly better than no randomization.
Can I identify device with MAC address?
3 Answers. MAC addresses can sometimes be used to identify the maker and potentially model of the device even without the device in hand. This is called the OUI (organizationally unique identifier).
Is spoofing your MAC address illegal?
While this is generally a legitimate case, MAC spoofing of new devices can be considered illegal if the ISP’s user agreement prevents the user from connecting more than one device to their service. Moreover, the client is not the only person who can spoof their MAC address to gain access to the ISP.
How do I make my Mac address private?
Open the Settings app, then tap Wi-Fi. Tap the name of the network you joined. If you haven’t joined the network yet, swipe left on its name and tap more . Tap to turn Private Address on or off.
How do I know if my MAC is randomized?
Fortunately it is easy to identify randomized MAC addresses. There is a bit which gets set in the OUI portion of a MAC address to signify a randomized / locally administered address. The quick synopsis is look at the second character in a MAC address, if it is a 2, 6, A, or E it is a randomized address.
Does VPN hide your MAC address?

How can I get rid of Mac randomization?
Turn MAC randomization off. Connect to the same network and verify that the factory MAC is being used. Delete the network by tapping Forget on the Network details page. Connect to the same network and verify that the same randomized MAC address is being used.
How to run a Mac randomization integration test?
To run an integration test, use the ACTS file, WifiMacRandomizationTest.py, located in tools/test/connectivity/acts/tests/google/wifi, to verify that the device uses the randomized MAC address and correctly stores the randomized MAC address for each network.
How is Mac randomization used in WiFi aware?
MAC randomization prevents listeners from using MAC addresses to build a history of device activity, thus increasing user privacy. Additionally, MAC addresses are randomized as part of Wi-Fi Aware and Wi-Fi RTT operations. To implement MAC randomization on your device:
