This is my first Apple TV, however I was reading for about a year how Yosemite would rename Apple TV and other network computers with crazy numbers on the end. As far as I read, Apple dumped discoveryd part-way through Yosemite and in iOS 9. Why then, is my new Apple TV 4 showing up on my El Capitan and iOS 9 devices with increasingly higher numbers tacked on the end? For reference, my Apple TV is connected by Ethernet to an AirPort Extreme. Does anyone know what's happening here?
