Changing Your Ubuntu Server 20.04 IP Address: Step-by-Step Guide

To change your Ubuntu Server 20.04 IP address, follow these steps:

Step 1: Identify the Current IP Address

To change your Ubuntu Server 20.04 IP address, you first need to identify the current IP address. You can do this by opening a terminal window and entering the following command:

ip addr show

This command will display a list of network interfaces and their associated IP addresses. Look for the interface that is connected to the network you want to change the IP address for.

Step 2: Edit the Network Configuration File

Once you have identified the interface you want to change the IP address for, you need to edit the network configuration file. You can do this by entering the following command:

sudo nano /etc/netplan/00-installer-config.yaml

This command will open the netplan configuration file in the nano text editor. Look for the section that corresponds to the network interface you want to change the IP address for. It should look something like this:

network:
version: 2

ethernets:
eth0:
dhcp4: yes

To change the IP address, you need to modify the dhcp4 line to static, and add the IP address, netmask, and gateway information, like this:

network:
version: 2

ethernets:
eth0:
dhcp4: no
addresses: [192.168.1.10/24]
gateway4: 192.168.1.1

Make sure to replace the IP address, netmask, and gateway information with your own network settings. Save the file by pressing Ctrl+X, then Y, then Enter.

Step 3: Apply the Changes

Once you have edited the netplan configuration file, you need to apply the changes. You can do this by entering the following command:

sudo netplan apply
