Privacy & Random MAC's
Some operating systems incorporate randomize MAC addresses to improve privacy.
This functionality allows you to hide the real MAC of the device and assign a random MAC when we connect to WIFI networks.
This behavior is especially useful when connecting to WIFI's that we do not know, but it is totally useless when connecting to our own WIFI's or known networks.
I recommend disabling this on-device functionality when connecting our devices to our own WIFI's, this way, NetAlertX will be able to identify the device, and it will not identify it as a new device every so often (every time iOS or Android randomizes the MAC).
Random MACs are recognized by the characters "2", "6", "A", or "E" as the 2nd character in the Mac address. You can disable specific prefixes to be detected as random MAC addresses by specifying the UI_NOT_RANDOM_MAC
setting.
