Question: What is MAC address randomization and why is it used?

Answer: MAC address randomization is a privacy-enhancing trend in device connectivity using a random, anonymous device identifier instead of the real address when connecting to wireless networks to prevent tracking. 

Question: What if we use MAC filtering on our network?

Answer: MAC randomization is an Android setting, not within uAttend's scope of support. Some clients have reserved and set a static IP address for the time clock when dealing with MAC filtering on their network.

LAN MAC addresses remain static and only change when the device is disconnected from the network.
