How Do I Know Which DNS Server Is Primary?


Larry Thompson

Have you ever wondered how to determine which DNS server is the primary one? In this article, we will explore different methods to identify the primary DNS server. Let’s get started!

Checking your router settings

If you are using a router to connect to the internet, it’s likely that your router is configured with a primary DNS server. To find out which DNS server your router is using as the primary one, follow these steps:

  • Step 1: Open your web browser and enter your router’s IP address in the address bar. The IP address is usually printed on a sticker located on the back or bottom of your router.
  • Step 2: Enter your username and password to access the router’s settings.

    If you haven’t changed them, the default username and password can be found in the user manual or on the manufacturer’s website.

  • Step 3: Once you are logged in, look for a section related to DNS settings. The location may vary depending on your router’s make and model.
  • Step 4: In the DNS settings section, you should see an option indicating the primary DNS server. It might be displayed as an IP address or a domain name.

If you have successfully followed these steps, you now know which DNS server is set as the primary one in your router configuration.

Using command prompt (Windows)

If you prefer using command prompt on Windows, there is a simple command that can help you find out which DNS server is currently being used as primary:

  • Step 1: Press the Windows key + R to open the Run dialog box.
  • Step 2: Type “cmd” and press Enter to open the command prompt.
  • Step 3: In the command prompt window, type “ipconfig /all” and press Enter.
  • Step 4: Look for the line that says “DNS Servers” or “Primary DNS Server”. The IP address listed next to it is your primary DNS server.

By following these steps, you can quickly determine the primary DNS server on your Windows machine using the command prompt.

Using Terminal (Mac)

If you are using a Mac, you can use the Terminal application to find out which DNS server is set as primary. Here’s how:

  • Step 1: Open Spotlight by pressing Command + Spacebar and search for “Terminal”. Click on the Terminal application to open it.
  • Step 2: In the Terminal window, type “networksetup -getdnsservers Wi-Fi” (replace “Wi-Fi” with your network interface name if you are not connected via Wi-Fi) and press Enter.
  • Step 3: The output will display a list of DNS servers. The first one in the list is your primary DNS server.

This method allows Mac users to quickly identify their primary DNS server using Terminal.

In conclusion

Determining which DNS server is set as primary doesn’t have to be a complex task. By checking your router settings or using command prompt/terminal, you can easily find out which DNS server is being used as the primary one. Remember, having the correct DNS server settings is essential for a smooth browsing experience.

Now that you know how to identify the primary DNS server, you can ensure your network is properly configured and troubleshoot any connectivity issues that may arise. Happy browsing!
