Setting Up a Static IP Address on Ubuntu

IP-address-image

Abstract

Learn how to configure a static IP address for your Ubuntu host.

1. Navigate to the Netplan Directory

Open your terminal and navigate to the Netplan directory: 

cd /etc/netplan

2. Edit the Installer Configuration File

Use a text editor to modify the installer configuration file: 

sudo nano 00-installer-config.yaml

3. Modify the Configuration

Change the content of the file, and make adjustments to your needs:

network:
  version: 2
  renderer: networkd
  ethernets:
    ens18:
      addresses:
        - 192.168.1.35/24
      routes:
        - to: default
          via: 192.168.1.1
      nameservers:
          addresses: [1.1.1.1, 8.8.8.8, 4.4.4.4]

Note

  • Replace ens18 with the appropriate network interface name (the one that is orginally in the network file).
  • Adjust the IP address (192.168.1.35/24) and default gateway (192.168.1.1) as needed.

By following these steps, you can assign a static IP address to your Ubuntu host. Make sure to save the configuration file and apply the changes for them to take effect.
