How to configure static IP address on Ubuntu 22.04 Jammy Jellyfish Desktop/Server

The purpose of this tutorial is to configure a static IP address on Ubuntu 22.04 Jammy Jellyfish Linux. When it comes to IP addresses on Ubuntu 22.04, you have two main options for how you configure your network interfaces. You can either obtain an IP address automatically with DHCP, or configure the system to use a static IP address, which never changes.

In this tutorial, we’ll show how to configure a static IP address on Ubuntu 22.04. This can be done either through GUI or command line, and we’ll be going over both methods. Once a static IP address is configured, it won’t change again unless you manually change the IP address later, or turn DHCP on.

In this tutorial you will learn:

• How to set static IP address on Ubuntu Desktop and Server
• How to set static gateway and DNS server

Follow the appropriate section below depending on whether you would like to configure a static IP address via desktop GUI or via command line.

Configure Static IP address on Desktop

1. Click on the top right network icon and select settings corresponding to the network interface you wish to assign with the static IP address.

   

2. Next, click on the gear box icon next to your network connection you wish to configure. This could be wired or wireless connection.

   

3. Click on the IPv4 or IPv6 tab, depending on which type of IP you want to configure. Then, select “manual” and fill in your desired IP address, subnet mask, and default gateway. Optionally, you can also fill in a DNS server. Click “apply” when you’re done.

   

4. Restart your network by using the provided ON/OFF switch.

5. Check your new static IP address configuration by clicking on the cog wheel.

   

Configure Static IP address on Server

In this example we will set a static IP address on the Ubuntu 22.04 server to 192.168.1.202/24 with default gateway to 192.168.1.1 and DNS servers 8.8.8.8, 8.8.4.4, and 192.168.1.1.

1. Locate and edit with administrative privileges the /etc/netplan/01-network-manager-all.yaml file with the following configuration. Update your desired static IP address, DNS server and gateway where appropriate:

   # This file is generated from information provided by
   # the datasource.  Changes to it will not persist across an instance.
   # To disable cloud-init's network configuration capabilities, write a file
   # /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
   # network: {config: disabled}
   network:
       ethernets:
           enp0s3:
               dhcp4: false
               addresses: [192.168.1.202/24]
               gateway4: 192.168.1.1
               nameservers:
                 addresses: [8.8.8.8,8.8.4.4,192.168.1.1]
       version: 2

   Save and exit the file when done.

   

2. To apply the new Netplan changes execute:

   $ sudo netplan apply
   

   Alternatively, if you run into some issues run:

   $ sudo netplan --debug apply

3. Confirm your new static IP address by using the ip Linux command:

   $ ip a
   

   

Troubleshooting

Question mark over the network icon on GNOME desktop

The question mark over the network icon on GNOME desktop means that from some reason the network internal self-check failed.

The workaround is to disable the Connectivity Checking switch.
