In this article, we will explore two methods on how to set a static IP address on Ubuntu: by modifying the
/etc/network/interfaces file and using the Network Manager GUI.
To set a static IP on Ubuntu, you can either modify the
/etc/network/interfaces file or use the Network Manager GUI. The first method is suitable for servers or headless machines, while the second method is more user-friendly for desktop users.

What is a Static IP?
A static IP address is a permanent Internet Protocol (IP) address assigned to a computing device. Unlike a dynamic IP address, which changes over time, a static IP address does not change.
Why Use a Static IP?
A static IP is essential for devices that need constant access, like servers and printers. This is because it allows other devices to reliably find and connect to the device with the static IP.
Method 1: Modifying
This method is more suitable for servers or headless machines that do not have a graphical interface.
Step 1: Open a Terminal
Open a terminal by pressing
Ctrl + Alt + T or by searching for ‘terminal’ in the application launcher.
Step 2: Switch to the Root User
Run the command
sudo -i to switch to the root user. The
sudo command allows you to run programs with the security privileges of another user (by default, the superuser). The
-i (simulate initial login) option runs the shell specified by the password database entry of the target user as a login shell.
Step 3: Open the Network Interfaces File
/etc/network/interfaces file using the command
nano /etc/network/interfaces. The
nano command opens the nano text editor, and
/etc/network/interfaces is the path to the network interfaces file.
Step 4: Modify the Network Interfaces File
Add the following lines for your wifi LAN adapter:
# The wifi network interface auto wlan0 iface wlan0 inet static address 192.168.0.87 netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 gateway 192.168.0.1 dns-nameservers 192.168.0.1 188.8.131.52 wpa-ssid <Your wifi network SSID> wpa-psk <Your hex encoded wifi WPA password>
In the above configuration:
auto wlan0brings the interface up at boot time.
iface wlan0 inet staticdefines the network interface and method.
address 192.168.0.87is the static IP address you want to assign to your computer.
netmask 255.255.255.0is the subnet mask for your network.
network 192.168.0.0is the network address.
broadcast 192.168.0.255is the broadcast address.
gateway 192.168.0.1is the default gateway.
dns-nameservers 192.168.0.1 184.108.40.206are the DNS servers.
wpa-pskare your WiFi details.
Step 5: Save and Exit
Ctrl + O to save the file and
Ctrl + X to exit nano.
Step 6: Restart the Networking Service
Restart the networking service using the command
sudo service networking restart.
Method 2: Using the Network Manager GUI
This method is more suitable for desktop users who prefer using a graphical interface.
Step 1: Open the Network Manager GUI
Open the Network Manager GUI. This can usually be found in the system tray or by searching for “Network” in the application launcher.
Step 2: Edit the Wifi Connection
Edit the wifi connection that you want to set a static IP for.
Step 3: Go to the IPv4 Tab
Go to the IPv4 tab.
Step 4: Set the Method to “Manual”
Set the Method to “Manual”.
Step 5: Enter the Network Information
Enter the following information:
- Address: xxx.xxx.xxx.xxx (your static IP address)
- Netmask: 24
- Gateway: xxx.xxx.xxx.xxx (your gateway address)
- DNS Server: xxx.xxx.xxx.xxx (your DNS server address)
Step 6: Save the Changes
Click “Apply” or “Save” to save the changes.
Setting a static IP address on Ubuntu is a straightforward process, whether you prefer using the command line or a graphical interface. Remember to replace the placeholder values with your actual network configuration. If you are still experiencing issues, double-check your network settings and ensure that your router is properly configured.
A static IP address is useful for devices that require constant access, such as servers and printers. It allows other devices to reliably find and connect to the device with the static IP.
Yes, you can set a static IP address using the Network Manager GUI. Method 2 in the article provides step-by-step instructions on how to do this.
Yes, there are advantages to using a static IP address. With a static IP, you have more control over your network and can easily set up services that require a fixed IP. It also allows for easier remote access to devices on your network.
Yes, you can set a static IP address for a wireless network connection. Both Method 1 and Method 2 in the article provide instructions for setting a static IP for a wifi LAN adapter.
No, setting a static IP address will not affect your internet connection speed. The speed of your internet connection is determined by your ISP and the quality of your network equipment, not by whether you have a static or dynamic IP address.
If you encounter issues after setting a static IP address, double-check your network settings to ensure they are correct. Make sure you have entered the correct IP address, netmask, gateway, and DNS server information. Additionally, check that your router is properly configured and that there are no conflicting IP addresses on your network.
