How to configure static IP address on Ubuntu 24.04

Introduction

If you like using the command line or need to set up a server without a GUI, the command line method is simple and effective.

Step 1: Open terminal

You can open Terminal by pressing Ctrl + Alt + T or searching for "Terminal" in the applications menu.

Step 2: Identify your network interface

Type the command ip link to see all network interfaces.

ip link

Find the interface you want to configure, such as eth0 for a wired connection or wlan0 for wireless.

Step 3: Edit your Netplan configuration

Ubuntu 24.04 uses Netplan to manage network settings. Find the Netplan configuration files in /etc/netplan/. Open a file with a text editor, for example type:

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

Step 4: Configure Static IP

Edit the file to add your static IP details. For example:

network:
 version: 2
 renderer: networkd
 ethernets:
 eth0:
 dhcp4: no
 addresses:
 - 192.168.1.100/24
 gateway4: 192.168.1.1
 nameservers:
 addresses:
 - 8.8.8.8
 - 8.8.4.4

Change eth0 to your network interface and adjust IP settings as needed.

Step 5: Apply your changes

Save the file and update the changes with sudo netplan apply.

sudo netplan apply

Check the new settings with ip addr show or by pinging another device.
