How Do I Turn Off Alternate DNS Server?

When it comes to managing your internet connection, understanding the Domain Name System (DNS) is essential. DNS is responsible for translating human-readable domain names into IP addresses, allowing your browser to load websites.

By default, your computer or router is configured to use a primary and alternate DNS server. However, there may be instances where you want to turn off the alternate DNS server for various reasons. In this tutorial, we will guide you through the process.

Step 1: Accessing Network Settings

To turn off the alternate DNS server, you first need to access your network settings. The steps may vary slightly depending on your operating system, but in general, you can follow these instructions:


  • Click on the Start menu and go to Settings.
  • Select “Network & Internet. “
  • Choose “Change adapter options.

  • Right-click on your active network connection and select “Properties. “


  • Click on the Apple menu and select “System Preferences.”
  • Choose “Network.”
  • Select your active network connection from the left sidebar.
  • Click on the “Advanced” button in the lower-right corner.

Step 2: Modifying DNS Settings

Once you have accessed your network settings, follow these steps to turn off the alternate DNS server:


  1. In the Properties window for your network connection, scroll down and locate “Internet Protocol Version 4 (TCP/IPv4)” or “Internet Protocol Version 6 (TCP/IPv6)” depending on your network configuration.
  2. Select the appropriate version and click on the “Properties” button.
  3. In the new window, make sure the option “Obtain DNS server address automatically” is selected.
  4. Click “OK” to save the changes.


  1. In the Advanced settings window, go to the “DNS” tab.
  2. You will see a list of DNS servers in the order of priority. The first one is your primary DNS server, and the second one is your alternate DNS server.
  3. Select the alternate DNS server entry and click on the minus (-) button to remove it from the list.

Once you have completed these steps, you have successfully turned off the alternate DNS server. It’s important to note that removing or disabling the alternate DNS server may affect your internet connection in certain scenarios. If you encounter any issues or need to troubleshoot connectivity problems, consider re-enabling it or contacting your network administrator for assistance.


In this tutorial, we walked you through the process of turning off the alternate DNS server. By following these steps and modifying your network settings, you can customize your DNS configuration according to your needs. Remember to exercise caution when making changes to these settings and always keep a backup of your original configurations.
