Just the other day I realised there is a new "link" in my Network in Finder. It is named openthread.thread.home.arpa

Any suggestions as to what that is?

I just noticed it too. No idea what it is. Just installed the Public Beta of Monterey, and that's when it showed up. Digging deeper someone said it has to do with Nest thermostats and things like that, but I don't have anything like that in the house.

Some sort of new Apple Home thing?
 
Anyone got an understanding of this, and why it's there? And importantly, how to remove it?

I have tried turning off Home, reseting networks etc. When I turn of wifi, it disappears, but immediately returns when turned back on. Using Hotspot on an iPhone, and it goes.

Really disappointing that no one seems to want to engage in this topic, but I guess they are all out there salivating at the return of the MagSafe!
 
I raised this issue, but it has gone away, and I no longer see it in my Finder. I am the RC client.

Do you have an HomePod mini?

As thread is an network protocol (very similar to zigbee used by hue lightbulbs) used by smart home devices and the HomePod mini works as thread border router allowing you to control them from your iPhone etc


its Still there for me on the RC build.
 
I just recently bought a HomPod Mini and now I see the openthread.thread.home.arpa icon in the Network in Finder. Probably something related to that? I'm running macOS Monterrey 12.0.1.

it would appear to be related to the HomePod mini thread border router capability and it goes away if I unplug my HomePod mini. Maybe something to do with the upcoming matter standard

I don't use HomeKit, nor do I have a HomePod, in many ways I have the most simple of setups, as other than Microsoft 365 (Word and Excel), yet I have this issue, from a clean install.
 
Completely wiped system, only device connected is my MacBook Pro, running todays public release of OS Monterey, and again I have the open thread.thread.open.arpa WTF

I also have openthread.thread.home.arpa showing up under networks. Does anyone know what this is or how to remove/delete it??
 
Damn - after the upgrade to Monterey RC the ICON shows up again...

Once upon a time, a bug like this would have the Mac Rumorites salivating at getting their teeth into a fix. Sadly these days, all that seems to get posted are; look at my/me new toy. Without the help and assistance to help users fix issues, what is the purpose going forward with this site?

I have "openthread.thread.home.arpa" on my network folder as well after upgrading to Monterey. I don't have a Google Nest or something and didn't change anything on my home network in the last days.

How to find out which device is this? Can we get the internal network IP of "openthread.thread.home.arpa"?

Edit: Might it have something to do with that?

I used Terminal to run "nslookup openthread.thread.home.arpa" and resolved the IP of my raspberry pi running Pi-Hole.

Thank so much, that is the solution! (not OP, but thanks heaps!)
 
I don't have any HomePods, Nest thermostats, or other thread devices. But I do have an AppleTV. And am seeing it too.
 
I just upgraded my AppleTV 4K to the latest, way faster, model and noticed the openthread address, and thought it sounded familiar. I tried HomeKit when it was released for Hue Lighting, but hated my phone kind of being the Home Kit hub, if you will. So this is nice, now if I can figure out how to use it on my Mac. Thanks to this forum, I was able to make the connection.

Anyway, this is where I saw "Thread"

Super old post but wanted to clarify for the people whom may stumble upon this eventually.

No, openthread.thread.home.arpa is not malware, and it is not a bug, it's simply, well as the name implies, a visible device running on your network, more specifically a thread border router, this may happen if you own a: HomePod, HomePod mini, recent AppleTV 4k or other thread border routers.
