I recently upgraded my Verizon Fios router to Gigabit. I was adding devices to the new WiFi network and noticed that as soon as I added my iPhone, two new MAC addresses appeared. The first corresponds to my iPhone’s private MAC, but I can’t figure out what the second MAC is for. It doesn’t appear to be my Apple Watch’s MAC. I also tried turning off my iPhone private MAC to see the underlying MAC, but that isn’t it either.
I tried changing the WiFi network name and password and each time the same thing happens (albeit with new MACs) when I go to add my phone
I did notice that this mysterious MAC always has an IP address that is +1 the value of the iPhone IP address. Otherwise, I’m at a complete loss.
Perhaps it’s related to AirPods case?
Any help would be appreciated!
