This is a repeatable bug.
While in sleep mode, the AppleTV3 spits out a DHCP request about once a minute. As soon as the device is awakened – pressing any key on the remote will do it – the requests stop until the lease expires.
Hi. Is Apple TV connected via ethernet? Do you know the lease duration? This is an old problem, see AppleTV 3 floods DHCP when ethernet connected which has persisted into the ATV 4.
I was wrong about one important detail: my device is actually an AppleTV 4! (Apologies.)
It is connected via ethernet and the IP lease duration is 1 hour.
I did read that other thread post prior to my original post. There is an important detail missing in that discussion, however, which I why I started a new topic. That is, the problem persists only when the AppleTV4 is asleep.
I'm hoping that it helps an Apple engineer to solve the issue.
Good point, and you should report it to Apple here https://www.apple.com/feedback/appletv.html. But it is a very long-standing issue, so solutions may not be forthcoming.
