How to Configure a Static IP Address in Ubuntu March 26, 2025

A Static IP Address is useful for servers, remote access, or network configurations where a fixed address is needed instead of a dynamically assigned one. This guide explains setting a static IP in Ubuntu using the GUI and terminal.

Let us follow the steps:

Method 1: Set a Static IP Using the GUI (Ubuntu Desktop)
If you are using Ubuntu Desktop, follow these steps:

1. Open Settings: Click on the network icon in the top-right corner and select Settings.
2. Select Network Interface: Choose Wired (Ethernet) or Wi-Fi, then click on the gear icon next to the connection.
3. Go to IPv4 Settings: Select the IPv4 tab.
4. Switch to Manual Mode: Under “Method,” select Manual instead of “Automatic (DHCP)”.
5. Enter Static IP Details:
   • Address: (e.g., 192.168.1.100)
   • Netmask: (e.g., 255.255.255.0)
   • Gateway: (e.g., 192.168.1.1)
   • DNS Servers: (e.g., 8.8.8.8, 8.8.4.4)
6. Save and Apply: Click Apply and restart the network connection.

Method 2: Set a Static IP Using the Terminal (Ubuntu Server)
For Ubuntu Server (or if you prefer CLI), follow these steps:

1. Find Your Network Interface
   Run:

   ip a

   Look for the interface name (e.g., eth0 or ens33).

2. Edit the Netplan Configuration File
   Ubuntu uses Netplan for network configurations. Open the config file:

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

3. Modify the File to Set a Static IP
   Replace the existing DHCP settings with the following (modify accordingly):

   network:
      ethernets:
        eth0:
          addresses:
             - 192.168.1.100/24
          gateway4: 192.168.1.1
          nameservers:
            addresses:
              - 8.8.8.8
              - 8.8.4.4
          dhcp4: no
    version: 2

   Replace eth0 with your interface name.
   Adjust 192.168.1.100, 192.168.1.1, and DNS servers as per your network.

4. Apply Changes.
   Save the file (CTRL + X, then Y, then Enter) and apply the new configuration:

   sudo netplan apply

5. Verify the New Static IP
   Check if the new IP is assigned:

   ip a

After setting up your static IP, you may need to clear your DNS cache. See our related guide: How to flush the local DNS cache in Linux server.
