How to Configure Static IP Address on Ubuntu Server 23.10

To configure a static IP address on Ubuntu Server 23.10, follow these steps:

Step 1 : Begin by updating the package list and installing net-tools:

sudo apt update

            nameservers:
                  addresses: [ "8.8.8.8", "8.8.4.4" ]

Step 4 : Apply the changes with the command:
