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?

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.
OK thanks. This makes sense. I guess if I’m going to go through the trouble of whitelisting the MAC, I can go and disable randomization on the device and assign it a static IP.
