And scroll to the Managing the loopback interface.
I also looked what is about wicked but for some reasons wicked seems gone?
Not really understanding, I did not see any update that required to uninstall wicked.
Anybody knows what is the use of "lo" and what is going on? Thank you, and this was a supplemental interesting reading.
I have to admit that I struggle to see if it is a usecase for me or not.
With the loopback interface always guaranteed to exist in one instance, a connection on a loopback interface can be used to specify configuration that’s always supposed to be applied. This includes things like adding an extra IP address or perhaps a DNS server.
Humm, not that I am very good in networking but as far as I understand what is written the use of lo is a kind of constituting a "template"? I find the new behavior a bit confusing. Before I had the ethernet cabled connection set up without IP to be used via the bridge (and that bridge would then serve and is necessary to me, as interface for my KVM virtual machines. Now however I have the loopback interface that is always there and always connected....to 127.0.0.1 but...my cabled ethernet connection is not shown anymore in the list, only lo and br0. And to make it more curious when I hover over the symbol of the Network manager in the tray, I DO(!) see three cabled ethernet lo, cabled ethernet enp7s0 and br0 interfaces. But not in the list of interfaces when I open it, there just lo and br0 Is this intentional? (If you happen to know of course).
