I've got an unknown Airplay device on a network that keeps showing up as "Apple TV" on my Mac and iPhone. I don't want to connect to it, but I would like to get some details on it (ideally a MAC address and/or IP address.) Is there a CLI utility buried in MacOS that I can use to enumerate Airplay devices and get more detail on them?

  • This is a bit broad - what you’re looking for can be obtained from the router/DHCP server lease table, or by issuing the command arp -a and looking for the AppleTV in the results. – Allan Sep 10 at 21:10
  • Looking through an ARP table doesn't help if I have neither an IP or MAC address to look for. It's intermittent and I'm not sure if there's something cached or what. To the best of my knowledge, I've never ever connected to an Apple TV. And AFAIK AirPlay is not routed, but there is not an Apple TV on my subnet. – miken32 Sep 12 at 17:28
  • You can also try pinging the broadcast address to “scan” your subnet. Eg. ping 192.168.1.255 you can get the broadcast address by issuing the command ifconfig en0 (or en1 depending on how you’re connected to your network – Allan Sep 12 at 17:41
