Configure Netplan & Network Interfaces on Linux Operating Systems
If your IP has changed, or if you wish to change your IP, you must edit the network configuration in your operating system. To do so, open your Terminal and run the following command.
sudo nano /etc/network/interfaces
This file may look like the following.
Edit the configuration as follows. Please note that individual configurations may look different from this.
Make sure not to change the loopback adapter config. Use the arrow keys to navigate through the configuration file and remove your old IP address, subnet, etc. Type in your new address information on each line. After the change, it will look something like the following screenshot.
Save the file and exit from the editor.
