Have you ever wondered how to find the DNS server IP address on your Ubuntu machine? Well, you’re in luck!

In this tutorial, we will walk you through the steps to easily locate your DNS server IP address. Let’s get started!

Method 1: Using the Command Line

If you prefer using the command line interface, follow these simple steps:

  1. Open a terminal by pressing Ctrl + Alt + T.

  2. Type the following command and press Enter:

  3. cat /etc/resolv.conf
  4. This will display the content of the resolv.conf file, which contains information about your DNS settings.

  5. Look for a line that starts with “nameserver”. The IP address next to it is your DNS server IP address.

Method 2: Using Network Manager

If you prefer a graphical user interface, Ubuntu provides a simple way to find your DNS server IP address using Network Manager:

  1. Click on the network icon in the top-right corner of your screen.

  2. Select “Wi-Fi Settings” or “Wired Settings”, depending on your network connection type.

  3. In the Network window that opens, click on the gear icon next to your connected network.

  4. A new window will appear. Go to the “IPv4” or “IPv6” tab, depending on your network configuration.

  5. You will see a field labeled “DNS”. The IP address listed there is your DNS server IP address.

Method 3: Using the Network Configuration File

If you prefer working directly with configuration files, you can also find your DNS server IP address by modifying the network configuration file:

  1. Open a terminal by pressing Ctrl + Alt + T.

  2. Type the following command and press Enter:

  3. sudo nano /etc/network/interfaces
  4. This will open the network interfaces file in the nano text editor.

  5. Look for a line that starts with “dns-nameservers”. The IP address listed next to it is your DNS server IP address.

  6. Press Ctrl + X, then type “Y” to save the changes, and finally press Enter.

In Conclusion

Finding your DNS server IP address on Ubuntu is a straightforward process. You can use either the command line, Network Manager, or directly modify the network configuration file.

Choose the method that suits your preferences and needs. Now you can easily locate your DNS server IP address and make any necessary changes to optimize your network settings!
