Larry Thompson

Are you an AT&T router user? Have you ever wondered if it’s possible to change the DNS server on your router?

Well, you’re in luck! In this article, we will explore the topic in depth and provide you with a step-by-step guide on how to change the DNS server on your AT&T router.

Why Change DNS Server?

Before we dive into the process of changing the DNS server on your AT&T router, let’s first understand why you might want to do it. The Domain Name System (DNS) is responsible for translating domain names into IP addresses. By default, your router uses the DNS settings provided by your internet service provider (ISP), which may not always be the most efficient or secure option.

Changing the DNS server can provide several benefits:

  • Better Performance: By using a faster and more reliable DNS server, you can experience improved browsing speed and reduced latency.
  • Enhanced Security: Some DNS servers offer additional security features like blocking malicious websites and preventing phishing attacks.
  • Access Geo-Restricted Content: Changing your DNS settings can help bypass geographical restrictions imposed by certain websites or streaming services.

The Process: Step-by-Step Guide

Please follow these steps to change the DNS server on your AT&T router:

  1. Accessing Your Router Settings

    The first step is to access your router’s settings. To do this, open a web browser and enter your router’s IP address in the address bar. Typically, this is either “” or “192.0.1”. Press Enter to proceed.

  2. Logging In

    Once you’ve reached the router’s login page, you will need to enter your username and password. If you haven’t changed these credentials before, try the default ones provided by AT&T.

    If you have changed them and don’t remember, you may need to perform a factory reset on your router.

  3. Navigating to DNS Settings

    After successfully logging in, navigate to the “DNS Settings” or “Network” section of your router’s configuration page. The exact location may vary depending on your router model.

  4. Changing DNS Server

    In this section, you will find options to change the DNS server settings. Look for fields labeled “Primary DNS” and “Secondary DNS”. Enter the IP addresses of the desired DNS servers into these fields. You can use popular public DNS servers like Google DNS (8.8.8 and 8.4.4) or Cloudflare DNS (1.1 and 1.1).

  5. Save Changes

    Once you have entered the new DNS server addresses, save the changes by clicking on the “Apply” or “Save” button at the bottom of the page.

  6. Restart Your Router

    To ensure that the changes take effect, it’s recommended to restart your router after modifying the DNS settings.


In conclusion, changing the DNS server on your AT&T router can offer numerous benefits, including improved performance, enhanced security, and access to geo-restricted content. By following the step-by-step guide provided in this article, you can easily change the DNS server settings on your AT&T router and enjoy a more optimized internet experience.

Remember to always keep a note of your original DNS settings in case you encounter any issues and need to revert back to them. Happy browsing!
