How Do I Replace My DNS Server?

Are you experiencing slow internet connectivity or facing difficulties in accessing certain websites? It could be due to your DNS server.

DNS (Domain Name System) is responsible for translating domain names into IP addresses, allowing you to browse the internet seamlessly. If your current DNS server is unreliable or slow, it may be time to replace it with a more efficient one. In this tutorial, we will guide you through the process of replacing your DNS server.

Step 1: Determine Your Current DNS Server

Before replacing your DNS server, it is essential to determine the current one being used by your computer or network. To do so:

  1. Open the Command Prompt on Windows or Terminal on macOS.

  2. Type ipconfig /all on Windows or cat /etc/resolv.conf on macOS and press Enter.

  3. Look for the “DNS Servers” entry in the output. This will display the IP address(es) of your current DNS server(s).

Step 2: Choose a New DNS Server

There are several public DNS servers available that offer better performance and reliability than default servers provided by ISPs (Internet Service Providers). Some popular options include:

  • Google Public DNS: Primary: 8.8.8, Secondary: 8.4.4

  • Cloudflare DNS: Primary: 1.1.1, Secondary: 1.0.1

  • OpenDNS: Primary:, Secondary: 208.220.220

You can choose any of these or explore other options based on your preferences.

Step 3: Change Your DNS Server

The process of changing your DNS server depends on your operating system:


  1. Open the Control Panel and navigate to “Network and Internet” > “Network and Sharing Center”.

  2. Click on “Change adapter settings” in the left sidebar.

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

  4. In the “Networking” tab, select “Internet Protocol Version 4 (TCP/IPv4)” and click on “Properties”.

  5. Select the option “Use the following DNS server addresses” and enter the IP addresses of your new DNS server(s).

  6. Click “OK” to save the changes.


  1. Click on the Apple menu and go to “System Preferences”.

  2. Select “Network”.

  3. In the left sidebar, choose your active network connection (Wi-Fi or Ethernet).

  4. Click on the “Advanced” button in the lower-right corner.

  5. Navigate to the “DNS” tab.

  6. Click on the “+” button to add a new DNS server.

  7. Enter the IP addresses of your new DNS server(s) and click “OK”.

Step 4: Test Your New DNS Server

Once you have changed your DNS server, it is crucial to ensure that it is functioning correctly. You can test it by:

  1. Opening a web browser.

  2. Navigating to a website you haven’t visited before.

  3. If the website loads correctly, it means your new DNS server is working as expected.

Congratulations! You have successfully replaced your DNS server, which should result in improved internet speed and reliability.

Note: In some cases, you may need to restart your computer or network devices for the changes to take effect.

In conclusion, replacing your DNS server can significantly enhance your internet browsing experience. By following this tutorial, you have learned how to determine your current DNS server, choose a new one, change it on Windows and macOS, and test if it is functioning correctly.
