What is lo in Network connections

After today’s update, I got another connection that I didn’t have before. And it cannot be removed, disconnected from it. What could it be?
Is Big Brother watching us?

lo is the loopback network device, it is present on all computers, you should only worry if you did NOT have one :wink:

Sometimes on certain computers it is not shown, but it IS always present…

Thanks for the tip, otherwise I already started encrypting data and disconnecting all devices from the network (just kidding).
Didn’t know about it. I’m surprised they only showed up today…

It’s a change in NetworkManager 1.42.
Will be fixed in Plasma 5.27.1.


I searched for the phrase lo network. I didn’t get clear information about it. I’m sorry for creating a burden.
