Syslog Error

Interesting that an Apple TV would request a prefix.

DNS / MDNS is completely unrelated.

Found this post in another forum:

 "The new Apple TV 4K supports the new Thread network protocol (https://en.m.wikipedia.org/wiki/Thread_(network_protocol)), which is IPv6 based. Since my network did not have IPv6, the Apple TV created an IPv6 network itself, so the devices on the network would be able to communicate to each other via Thread and to the Apple TV."

I think Sonos also creates its own little network so it can communicate with other Sonos devices.

Locking the DNS in the Apple TV did not fix the debug problem either.
