How to Configure Static IP Address on Ubuntu Server

Usually, when a client system connects to a network via WiFi or an ethernet cable, it automatically picks an IP address from the router. This is made possible through the DHCP server which auto-assigns IP addresses to clients from a pool of addresses.

A Static IP address is recommended for servers as the static address does not change as oppose to a dynamic IP address assignment via DHCP server.

In this guide, We will learn How to Configure a Static IP Address on Ubuntu Server 22.04 | 20.04 LTS with Netplan

Step 1 – Check the name of Network interface

First of all, We need to check the name of Network interface by execute following command below:

ip addr

#or

ip link

#or

ifconfig

Output as below:

From the output, my network interface is ens33 and IP Address as 192.168.1.201

Step 2 – Configure static IP Address

Go to the /etc/netplan directory and find YAML configure file

cd /etc/netplan

ll

In this case, my YAML file is 00-installer-config.yaml

Now, open 00-installer-config.yaml file by execute the command below:

sudo vim 00-installer-config.yaml

Comment default lines and add new content below. Be mindful of the spacing in the YAML file.

network:
 version: 2
 renderer: networkd
 ethernets:
  ens33:
   dhcp4: no
   addresses:
    - 192.168.1.20/24
   nameservers:
    addresses: [8.8.8.8, 8.8.4.4]
   routes:
    - to: default
      via: 192.168.1.1

Configuration file like below:

Save and exit file by press Esc Shift :x Enter

And run the command below for the change to take effect:

sudo netplan appy

Then finally, you check the new IP address using the command below:

ip addr

Perfect! The IP address has now changed successfully.
