To configure a static IP address using the new NetPlan tool, the file should look like this: IPv4 address (192.168.1.2), Gateway (192.168.1.1), DNS Servers (8.8.8.8,8.8.4.4)

Run the commands below to create a new network configuration file

sudo nano /etc/netplan/01-netcfg.yaml

Then configure IPv4 addresses as shown below… take notes of the format the lines are written…
