How to Fix DNS Issues in Windows 10: A Step-by-Step Guide

If you’re having trouble with DNS issues on Windows 10, don’t worry—you’re not alone. DNS, which stands for Domain Name System, is like your computer’s phone book, translating website names into IP addresses so that you can access them. When DNS issues occur, websites may not load or your internet connection may become sluggish. Fixing these problems can usually be done by changing settings or resetting network components. Below, I’ll guide you through some simple steps to resolve DNS issues on your Windows 10 computer.

Fixing DNS Issues on Windows 10

In this section, you’ll learn how to troubleshoot and fix DNS issues on your Windows 10 PC. Each step will address a different aspect of the problem, ensuring you cover all bases.

Step 1: Restart Your Router and Computer

Before diving deep, restart your router and computer. This simple trick often resolves connectivity issues.

Sometimes, temporary glitches cause DNS failures. By restarting, you refresh your network settings and clear any temporary issues that might be the culprit.

Step 2: Clear Your DNS Cache

Flush the DNS cache using the Command Prompt. This action removes outdated information stored from previous connections.

Open Command Prompt as an administrator. Type ipconfig /flushdns and press Enter. This command clears the DNS cache, ensuring your computer accesses the most updated web addresses.

Step 3: Change Your DNS Server

Switch to a public DNS server like Google’s or Cloudflare’s. This can improve speed and reliability.

Go to Network and Sharing Center, then change adapter settings. Right-click your connection, navigate to Properties, and select Internet Protocol Version 4 (TCP/IPv4). Enter preferred DNS addresses like 8.8.8.8 for Google.

Step 4: Reset TCP/IP Stack

Use the Command Prompt to reset TCP/IP stack. This action can often resolve deep-seated network problems.

In Command Prompt, type netsh int ip reset and press Enter. This reset adjusts network settings to default, which can help fix persistent issues.

Step 5: Disable IPv6

Temporarily disable IPv6 to check if it’s causing conflicts. Many networks still primarily use IPv4.

In Network and Sharing Center, right-click your connection, go to Properties, and uncheck Internet Protocol Version 6 (TCP/IPv6). This temporary change can help diagnose if IPv6 is the root cause.

Once you’ve completed these steps, your DNS issues should be resolved. Your computer will connect more efficiently to websites, resulting in faster load times and improved browsing experience.

DNS Issues on Windows 10: Tips

  • Consider setting a static DNS address for consistency, especially in frequently used networks.
  • Regularly update network drivers to maintain compatibility with new Windows updates.
  • If you use a VPN, verify that its settings aren’t conflicting with your DNS.
  • Use network troubleshooting tools in Windows for automated diagnostics.
  • Keep firewall settings checked to ensure they aren’t blocking DNS requests.
