Interesting and new to me is that my network interface which was known to be called eth0 is now called eno16777736 in my new installs.

The following document indicates that 16777736 is the device’s acpi_index as provided by the firmware (BIOS/EFI)

This seems to happen on my VMware hosts where I’ve installed the latest Ubuntu OS releases. I am still looking into why this is happening and will update as soon as I have a better understanding.

For now, here is some info I found:

What does “eno” stand for?

en is for Ethernet
o is for on-board
The number is a firmware/BIOS provided index.
