How to Set a Static IP Address on Ubuntu Server 22.04

Setting a static IP address on Ubuntu Server 22.04 ensures that your server always has the same IP, which is essential for services like web hosting, file sharing, and remote access. Follow this guide to configure a static IP manually.

Step 1: Identify Your Network Interface

First, determine the name of your network interface. Run the following command:

ip a

Look for an interface name like eth0 or ensXXX. Take note of it.

Step 2: Edit Netplan Configuration File

Ubuntu 22.04 uses Netplan for network configuration. Open the Netplan configuration file with a text editor:

sudo nano /etc/netplan/00-installer-config.yaml

If the file is different, locate it in /etc/netplan/ by listing files:

ls /etc/netplan/

Step 3: Configure the Static IP Address

Modify the configuration to include a static IP. Replace ensXXX with your actual network interface name:

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

• addresses: Set your desired static IP.

• gateway4: Set the default gateway (usually the router’s IP).

• nameservers: Define DNS servers (Google’s DNS is used in this example).

Step 4: Apply the Configuration

Save the file (CTRL + X, then Y and ENTER). Apply the changes using:

sudo netplan apply

To verify the new IP address, run:

ip a

Step 5: Use an Automatic Code Generator

Instead of manually writing the configuration, you can use the Static IP Address Code Generator to generate the correct Netplan YAML code. Simply enter your network details, and copy-paste the generated code into your configuration file.

Setting a static IP on Ubuntu Server 22.04 is simple and ensures stable network connectivity. Whether configuring manually or using an automatic generator, ensure your settings match your network environment for seamless connectivity. Don’t forget to comment 😉
