If I’m creating a whitelist for a mobile device on my network and that device is using a randomized MAC, is it going to work at all? How are randomized MACs not a nightmare on small networks?

    I see. Thanks.

    What other way is there if the the IP is dynamic. I thought to create a whitelist for devices I had to add the client’s MAC to the custom group. It seems to work fine so far. I was just concerned that it wouldn’t continue to work if the iPhone changed its MAC.

      That person is missing the point that a randomized MAC will often get a different DHCP lease, and the MAC address is used in that, so the IP address will change.

      On a trusted Wi-Fi network, disable MAC randomization on your clients, and if possible reserve an IP address for their non-random MAC address. Some devices have deterministic random per WiFi network, which could also work. In iOS this is WiFi network -> private WiFi address “fixed”. “Rotating” would cause your pihole problems.
