Thanks for the commands!

Results:
--------
On two Ubuntu 20.04.3 desktop machines:
1st command:
enp0s25
wlo1

2nd command
enp0s25
wlo1

On one Ubuntu 20.04.3 *server*, which has been release-upgraded from 16 to 18
before finally to 20:
1st command
eth0
wlan0

2nd command
tun0
tun1
eth0

So on the server the results vary between the commands but not on the desktops.


I still wonder about the real reason for changing the names...
Bitcoin mining with thousands of units all interconnected?
