Ubuntu 16.04: Where is the network configuration?
I am using Ubuntu 16.04. In the past, I have always configured my network through the /etc/network/interfaces file but for this install, I have used the 'Edit Connections' option from the Gnome taskbar network menu. My network is configured and works, but the interfaces file just contains
auto lo
iface lo inet loopback
So, where is the actual configuration for the network stored and why is it not in the interfaces file?

I keep coming back to this answer. Maybe it's my bad memory, but whatever the case, I'd like to award it an extra thank you. :)

If you setup a connection using Network Manager, it is stored in
/etc/NetworkManager/system-connections/
A file for each connection is created there.

Thanks for clearing that up. I'd still like to know why this tool can't just put this configuration information in the /etc/network/interfaces file. Why use one way when you can have multiple confusing ways to do the same thing, eh?

These are different ways of setting network. If you edit/etc/network/interfaces, NM will be disabled. Nothing is confusing. For a desktop forget about theinterfacesfile ;-)
