Set up Static IP Address on Ubuntu Server 20.04 / 22.04 / 24.04

Update October 2024: Added instructions for Ubuntu 24.04

When setting up a virtual machine in the local network / homelab, you should set up a static IP for the machine to ensure services operate smoothly, without interruption because the IP is changed after each reboot.

In this article, I will share how to set up a static IP address on a computer with Ubuntu Server 20.04 / 22.04 / 24.04 installed.

Set up static IP on Ubuntu Server

First check the current IP and network port of the computer with the command

ip addr showCode language: Nginx (nginx)

2: eth0:  mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 00:15:5d:00:64:00 brd ff:ff:ff:ff:ff:ff
    inet 192.168.0.132/24 brd 192.168.0.255 scope global dynamic eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::215:5dff:fe00:6400/64 scope link
       valid_lft forever preferred_lft foreverCode language: YAML (yaml)

The current IP of the eth0 network port is being set in dynamic IP mode from the Router’s DHCP Server.

Check gateway and DNS parameters with command

networkctl statusCode language: Nginx (nginx)

● Interfaces: 1, 2
       State: routable
Online state: online
     Address: 192.168.0.132 on eth0
              fe80::215:5dff:fe00:6400 on eth0
     Gateway: 192.168.0.1 on ens18
         DNS: 1.1.1.1Code language: YAML (yaml)

We need to record 2 parameters Gateway and DNS to configure in the next step

Since Ubuntu 20.04, network configuration is set up and managed by the netplan tool. To change to a static IP, we need to edit the file 00-installer-config.yaml in folder /etc/netplan

sudo nano /etc/netplan/00-installer-config.yamlCode language: Nginx (nginx)

For Ubuntu 22.04/24.04edit the file Content as follows, save (Ctrl + O) and exit (Ctrl + X)

# This is the network config written by 'subiquity' 
network:
  ethernets:
    eth0:
       dhcp4: no
       addresses: (192.168.0.5/24)
      routes:
        - to: 0.0.0.0/0
          via: 192.168.0.1
       nameservers:
             addresses: (1.1.1.1, 1.0.0.1, 8.8.8.8, 8.8.4.4)

  version: 2Code language: YAML (yaml)

For Ubuntu 20.04edit the file content as follows, save (Ctrl + O) and exit (Ctrl + X)

# This is the network config written by 'subiquity' 
network:
  ethernets:
    eth0:
       dhcp4: no
       addresses: (192.168.0.5/24)
       gateway4: 192.168.0.1
       nameservers:
             addresses: (1.1.1.1, 1.0.0.1, 8.8.8.8, 8.8.4.4)

  version: 2Code language: YAML (yaml)

Depending on the subnet of the internal network you are using, you will adjust the addresses and gateway4 accordingly.

In the nameservers address line, you can use CloudFlare’s DNS (1.1.1.1 and 1.0.0.1) or Google’s (8.8.8.8 and 8.8.4.4) or both. Or if you have AdGuard Home set up on your local network, you can replace it with the IP of the device where AdGuard Home is installed.

Next run the command netplan apply to apply the newly changed parameters

sudo netplan applyCode language: Nginx (nginx)

Check the machine’s IP again, it has now been converted to 192.168.0.5 as set in the netplan configuration file.

ip addr showCode language: Nginx (nginx)

2: eth0:  mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 00:15:5d:00:64:00 brd ff:ff:ff:ff:ff:ff
    inet 192.168.0.5/24 brd 192.168.0.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::215:5dff:fe00:6400/64 scope link
       valid_lft forever preferred_lft foreverCode language: YAML (yaml)

That’s it. Your server already has a static IP address, ready to install services such as AdGuard Home, WireGuard, Nginx Proxy Manager,…
