How to Fix DNS Issues

Introduction

DNS (Domain Name System) issues can cause websites to fail to load or show incorrect content. This guide covers troubleshooting DNS-related issues.

Common Causes

• Incorrect DNS settings
• DNS server unavailability
• Corrupted DNS cache
• Firewall or antivirus interference

Solutions

1. Clear DNS Cache: Open Command Prompt and type ipconfig /flushdns to clear the DNS cache.
2. Change DNS Server: Use Google's DNS (8.8.8.8, 8.8.4.4) or Cloudflare's DNS (1.1.1.1) for faster and more reliable connections.
3. Check Firewall Settings: Make sure your firewall isn't blocking DNS requests.
4. Restart Router: Restarting your router can help resolve temporary DNS server issues.
