This new tool replaces the static interfaces (/etc/network/interfaces) file that had previously been used to configure Ubuntu network interfaces.
Now you must use /etc/netplan/*.yaml to configure Ubuntu interfaces.
The new interfaces configuration file now live in the /etc/netplan directory.
A file called 01-netcfg.yaml is used to configured the first interface.
Below is the default configuration for a interface using DHCP.

network:
version: 2
renderer: networkd

dhcp4: yes
dhcp6: yes
