Step-by-Step Guide: How to Change DNS Windows 11 for Optimal Performance

In today’s digital landscape, a smooth and secure internet experience is paramount. While your internet service provider (ISP) provides you with a default DNS (Domain Name System) server, switching to a custom DNS server can significantly enhance your browsing speed, security, and privacy. This guide will walk you through the process of how to change DNS on Windows 11, empowering you to take control of your online experience.

Understanding DNS: The Backbone of the Internet

Before delving into the steps, let’s understand what DNS is and why changing it matters.

DNS acts as the internet’s phonebook, translating human-readable domain names like “google.com” into numerical IP addresses that computers understand. When you type a website address into your browser, your computer queries a DNS server to find the corresponding IP address. This process happens behind the scenes, ensuring you can access websites without needing to remember complex IP addresses.

Why Change Your DNS?

While your ISP’s default DNS server works, opting for a custom DNS server can offer several advantages:

• Faster Website Loading: Some DNS providers prioritize speed and efficiency, resulting in quicker website load times.
• Enhanced Security: Public DNS servers like Cloudflare and Google DNS offer robust security features, protecting you from malicious websites and phishing attacks.
• Privacy Protection: Certain DNS servers prioritize user privacy, preventing tracking and logging of your browsing activity.
• Content Filtering: Some DNS servers allow you to block specific websites or categories, ideal for families with children.

Methods to Change DNS in Windows 11

Now, let’s explore the different ways to change your DNS settings in Windows 11:

1. Changing DNS Through Network Settings

This method is the most straightforward and readily accessible:

1. Open Network Settings: Right-click on the network icon in your taskbar and select “Open Network & Internet settings.”
2. Select Wi-Fi or Ethernet: Choose the active network connection (Wi-Fi or Ethernet) from the left-hand menu.
3. Click “Change adapter options“: This opens the classic Network Connections window.
4. Right-click your network: Right-click on the active network connection (Wi-Fi or Ethernet) and select “Properties.”
5. Choose “Internet Protocol Version 4 (TCP/IPv4)”: Double-click on “Internet Protocol Version 4 (TCP/IPv4)” in the list of components.
6. Select “Use the following DNS server addresses“: Choose this option and enter the desired DNS server addresses in the designated fields.
7. Enter DNS Server Addresses: Enter the preferred DNS server addresses, separated by a comma.

• Public DNS Servers:
• Google Public DNS: 8.8.8.8, 8.8.4.4
• Cloudflare DNS: 1.1.1.1, 1.0.0.1
• OpenDNS: 208.67.222.222, 208.67.220.220
• Private DNS Servers: If you’re using a private DNS service, refer to their documentation for the specific addresses.

8. Click “OK” to save the changes: Close all open windows to apply the new DNS settings.

2. Changing DNS Through Command Prompt

For a more advanced approach, you can use the Command Prompt:

1. Open Command Prompt: Search for “cmd” in the Windows search bar and run it as administrator.
2. Enter the following command: `netsh interface ip set dns name=”Ethernet” source=static addr=8.8.8.8 register=primary` (Replace “Ethernet” with the name of your network connection and “8.8.8.8” with your preferred primary DNS server address).
3. Enter the following command: `netsh interface ip set dns name=”Ethernet” source=static addr=8.8.4.4 register=secondary` (Replace “Ethernet” with the name of your network connection and “8.8.4.4” with your preferred secondary DNS server address).
4. Close Command Prompt: The changes will be applied automatically.

3. Changing DNS Through Registry Editor

This method is for experienced users and should be approached with caution:

1. Open Registry Editor: Search for “regedit” in the Windows search bar and run it.
2. Navigate to the DNS settings key: Go to `HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParametersInterfaces`.
3. Find the relevant Interface ID: Each network interface has a unique ID. You can identify the correct ID by comparing the IP address with the one displayed in your Network Connections window.
4. Modify the DNS server addresses: Double-click on the “NameServer” value and enter the preferred DNS server addresses, separated by commas.
5. Exit Registry Editor: Close Registry Editor and restart your computer to apply the changes.

Choosing the Right DNS Server for You

With numerous DNS providers available, choosing the right one for your needs can be overwhelming. Here’s a quick guide to help you decide:

• Google Public DNS: Offers high speed and security features, making it a popular choice for general browsing.
• Cloudflare DNS: Focuses on privacy and security, blocking malware and phishing attempts.
• OpenDNS: Provides robust content filtering and parental control features, ideal for families.
• Quad9: Prioritizes privacy and security, offering DNS-over-HTTPS (DoH) for enhanced protection.

Testing Your DNS Settings

After changing your DNS settings, it’s essential to test if the changes have been applied successfully. Here’s how:

1. Open Command Prompt: Run Command Prompt as administrator.
2. Use the `ipconfig` command: Type `ipconfig /all` and press Enter. This will display details about your network configuration, including the current DNS server addresses.

Beyond Basic Settings: Advanced DNS Features

While changing the basic DNS settings is a good starting point, some DNS providers offer advanced features that can further enhance your online experience:

• DNS-over-HTTPS (DoH): Encrypts DNS requests, protecting your privacy and preventing eavesdropping.
• DNS-over-TLS (DoT): Offers similar security benefits to DoH, using TLS encryption.
• Custom DNS Records: Allows you to control how your domain name is resolved, useful for website administrators.

The Final Word: Unlock Your Internet’s True Potential

Changing your DNS settings in Windows 11 is a simple yet impactful step towards a faster, more secure, and private internet experience. By leveraging the power of custom DNS servers, you can take control of your online journey and enjoy a smoother, more enjoyable browsing experience.

Answers to Your Questions

Q1: Can I change my DNS settings back to the default?

A: Yes, you can easily revert to your ISP’s default DNS settings by following the same steps outlined above and selecting “Obtain DNS server address automatically” in the TCP/IPv4 properties.

Q2: Is it safe to use a public DNS server?

A: Reputable public DNS servers like Google Public DNS and Cloudflare DNS are generally safe and secure. However, research the provider thoroughly before switching to ensure their practices align with your privacy and security expectations.

Q3: Will changing my DNS affect my internet speed?

A: Switching to a faster DNS server can actually improve your website loading speeds. However, if you choose a DNS provider that is geographically far from your location, it may slightly increase latency.

Q4: Are there any downsides to using a custom DNS server?

A: While the benefits of custom DNS servers outweigh the downsides, potential drawbacks include:

• Potential for DNS hijacking: Using an untrusted DNS server can expose you to security risks.
• Geo-location restrictions: Some websites may restrict access based on your location, and a custom DNS server might affect this.

Q5: How often should I change my DNS settings?

A: You can change your DNS settings at any time. However, unless there’s a specific reason to switch (like a change in your ISP), your current DNS server should work fine.
