How to Configure Static IP Address on Ubuntu Server 24.10

To configure a static IP address on Ubuntu Server 24.10, follow these simple steps.

Step 1 : Update and Install net-tools

First, update your server and install the net-tools package, which includes essential networking utilities like ifconfig.

sudo apt update
sudo apt install net-tools

Step 2 : Check Ethernet Interfaces

Use the ifconfig -a command to list all the Ethernet interfaces available on your server. Identify the interface for which you want to set a static IP address (e.g., eth0 or enp0s3).

ifconfig -a

Step 3 : Open the Netplan Configuration File

Next, open the Netplan configuration file located at /etc/netplan/50-cloud-init.yaml. Use your preferred text editor (like nano or vim).

sudo nano /etc/netplan/50-cloud-init.yaml

Step 4 : Add Static IP Configuration

In the configuration file, modify or add a section for the Ethernet interface to configure a static IP. Here's an example configuration:

network:
    ethernets:
        enp0s3:
            dhcp4: no
            dhcp6: no
            addresses: [192.168.1.30/24]
            routes:
                - to: default
                  via: 192.168.1.1
            nameservers:
                  addresses: [ "8.8.8.8", "8.8.4.4" ]
    version: 2

Step 5 : Apply the Changes

After saving the file, apply the changes to the network configuration by running the following command:

sudo netplan apply

Step 6 : Check Connectivity

To verify that the static IP has been successfully applied, ping an external server like Google:

ping google.com

Congratulations! You have successfully configured a static IP address on your Ubuntu Server 24.10.
