AppleTV 4k is or has two ipv4 addresses showing in router

Is is possible that appletv 4k is attempting to reserve an ipv6 address and ipv4 address, even with ipv6 shut down at the eero router? There are two ip’s listed under the same hostname xxx.xxx.xxx.x24 (active) and xxx.xxx.xxx.x31 which is unreachable.

New Apple TV 4K acting as router and giving out IPv6 (ULA) addresses I run a strictly IPv4 network as my ISP does not support IPv6 and some devices in my network still not ready for it. On my router I have disabled it on kernel level, so there is no way IPv6 is able to get into my network, or so I thought. Since about a week ago I started noticing that my computer and iPhone started getting IPv6 unique local addresses (ULA), so nothing on the internet, but still. They were in the range of fd94:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx. I immediately went to the router and double checked all the settings, IPv6 was seemingly still disabled and the IPv6 ULA-Prefix was also empty. I tried some different settings, but I still kept getting an IPv6 address on my devices. It seemed to me that a device inside my network was giving out these addresses, but which one? I started by removing all cables one by one from the switch and noticed that I did not receive an IPv6 address when the cable to the TV (and related devices) was unplugged. Checking further I noticed that the new 2021 Apple TV 4K was the culprit. Unplugging it made my whole network clean of IPv6, replugging made them receive IPv6 ULAs again. I tried resetting the Apple TV multiple times, but this did not solve the problem. I also set it up without logging into iCloud, not using any previously saved settings. After resetting the Apple TV, the IPv6 address range it was giving out only changed (from fd94:... to fd53:...). To be completely sure that it is not my own router I tried two different routers, with IPv6 disabled, but to no avail. When the Apple TV was not plugged in I only received an IPv4 address, but when it was plugged in I also received an fd53:... address (see the following images). Is this a known bug? And is there possibly a solution to this? Or is my new Apple TV faulty? Some devices in my network cannot handle IPv6 (ULA) addresses, so I can basically not have this device connected to it (unless completely isolated in a VLAN). I am currently running the latest version of tvOS 14.6. Updating from 14.5 to 14.6 went fine. I also tried using "Reset and Update," to possibly clean install the software, but I received an error message saying "Apple TV can't download the latest update right now. Try again later." This might be tied this same bug, where the Apple TV possibly tries to check for an update on an IPv6 server, but has no possible connection to it.

AppleTV presents multiple MAC addresses, sends packets to non-existent local IPs Monitoring our AppleTV on our router, I've noticed two odd things with it (connected only via WiFi): The AppleTV will present three different MAC addresses to DHCP to get IP addresses. I think this is the AppleTV as the HomeKit controller grabbing IP addresses for a pair of connected HomePods, but am not sure. One MAC is the one you see from within the AppleTV menus, the other two are apparently randomly generated and are not the same from reboot to reboot. The AppleTV is sending a couple of packets per minute to local (non-routable) IP addresses that do not and have never been on our LAN: 10.0.0.135 192.168.0.148 192.168.99.177 192.168.99.185 192.168.99.200 They are TCP to port 7000, which I understand to be involved with Airplay. But, again, those have never been legitimate subnets for us and our AppleTV was brand new and never used on any other network. (There's the possibility that the 192.168.0.148 IP was from the initial setup of our network -- a couple of years ago now -- when the router might've defaulted to the 192.168.0 subnet. But not the others.)

Changing WiFi on AppleTV We recently changed our home Wi-Fi to a mesh network, and we have not been able to reset our AppleTV Wi-Fi. We have gone into settings in AppleTV (with the remote, displayed on the TV) and carefully put in the new network and password using correct case sensitive login and it just doesn’t recognize it. I have also gone into the AppleTV app on my iPad to try to reset it from there, but under TV there is no Settings mode (even when I search, it doesn’t have a Settings mode). Any advice on what’s wrong or what to try?

One of them would not be IPv6, as that would look very different (longer, and with colons instead of dots). Both numbers are IPv4. The Apple TV is happy with one IPv4 address, and does not try to ‘reserve’ another address.

Something else is happening. Have you tried restarting the router?
