Studio Display Ethernet Adapter

I bought a Mac mini and a Studio Display in March 2023 and now I realized that the Ethernet interface of the studio display is sending packages continuously to another device and that device respond and I don’t know what device it is. it”s using ipv6 address even that the ipv6 address of my Mac mini is set to local link and not connected to the internet.

The Studio Display firmware is 16.4 (Build 20F246)

I succeeded to stop it with sudo ifconfig en6 down when the Mac mini was not connected to the Internet, but if the Mac mini is connected to the Internet, I cannot stop the connection, the command it’s not working.

Any idea?

Thank you.

How are you observing this communication? Can you observe the content of the packets?

The delay between the outgoing packet and the response will give you a clue about how far away the recipient is!

Port number?
