I've recently set up arpwatch with notifications. It's working perfectly however every few minutes my apple TV keeps flip flopping MAC addresses. The apple tv is wired into the network (ethernet) therefore wifi should be disabled. Also to add, my internal Wifi has a hidden SSID as well as MAC filter and the MAC of the Apple TV isn't permitted so there's no way for it to get on the wifi.
I have a second Apple TV that's only on wifi and doesn't flip flop.
The question in this post is how to disable flip flop entirely or for a specific device IP or set of MAC addresses.
