DNS Issues – Domain Names Not Resolving Correctly

Encountering DNS issues can be frustrating, especially when domain names aren’t resolving as they should. This problem can prevent you from accessing websites, disrupting work or leisure activities. Understanding and troubleshooting DNS errors can save time and restore connectivity quickly. Here’s how to address DNS resolution issues.

1. Check Your Internet Connection

Before diving into DNS-specific solutions, ensure your internet connection is stable. A dropped connection can mimic DNS issues. Restart your router and check if other devices on the network are experiencing similar problems.

2. Clear DNS Cache

Outdated or corrupted DNS cache can cause websites not to load.

  • Windows: Open Command Prompt as Administrator and type ipconfig /flushdns.

  • Mac: Open Terminal and enter sudo killall -HUP mDNSResponder.

  • Linux: Use sudo systemd-resolve --flush-caches or restart the network service.

3. Restart Your Router and Device

A simple restart can resolve DNS conflicts. Power off your router for at least 10 seconds, then turn it back on. Restarting your computer or mobile device can also refresh network settings.

4. Change DNS Server Settings

Sometimes, the default DNS server from your Internet Service Provider (ISP) may be slow or temporarily down. Switching to a public DNS server can resolve the issue.

  • Recommended DNS Servers:

    • Google DNS: 8.8.8.8 and 8.8.4.4

    • Cloudflare DNS: 1.1.1.1 and 1.0.0.1

    • OpenDNS: 208.67.222.222 and 208.67.220.220

  • Windows: Go to Control Panel > Network and Sharing Center > Change adapter settings, right-click your network, and select Properties. Change the DNS settings under Internet Protocol Version 4 (TCP/IPv4).

  • Mac: Go to System Preferences > Network, select your network, and adjust the DNS settings.

5. Disable Firewall or Antivirus Temporarily

Sometimes, overprotective firewall or antivirus settings block DNS requests. Temporarily disabling these can help identify if they’re causing the issue. Remember to re-enable them after testing.

6. Test Using Another Device or Network

Check if other devices on the same network experience the issue. If only one device is affected, the problem likely lies with its settings. Alternatively, try accessing the website using mobile data to determine if the issue is network-specific.

7. Run Network Troubleshooter (Windows Only)

  • Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters.

  • Select Internet Connections and follow the prompts.

8. Contact Your ISP

If none of the above steps work, your ISP may be experiencing DNS issues. Reach out to them for assistance.
