- Check Your Internet Connection: Make sure your internet connection is working properly. Sometimes, DNS issues can be caused by a problem with your internet service provider (ISP) or network connection. To check the internet connection ,try Accessing a Website: Open a web browser and try accessing a website you know is functioning properly, such as google.com or cnn.com. If the website loads successfully, it indicates that your device is connected to the internet.
2. Restart Your Router or Modem: A simple restart of your router or modem can often fix DNS issues. Unplug the power cable, wait for a few minutes, then plug it back in and restart the device.
3. Flush DNS Cache: Open the command prompt (CMD) as an administrator and type the command: ipconfig /flushdns.
4. Change DNS Servers: You can try using alternative DNS servers such as Google DNS (8.8.8.8 and 8.8.4.4) or OpenDNS (208.67.222.222 and 208.67.220.220). You can change your DNS settings in your network adapter properties.
5. Check Firewall and Security Software:Make sure your firewall or security software isn’t blocking DNS traffic.
Steps Checking firewall or security software isn’t blocking:
A. Open your firewall settings or control panel. Look for any settings related to DNS or network traffic filtering. Ensure that DNS traffic is allowed through the firewall. This might involve adding exceptions or allowing specific ports or protocols used by DNS (such as UDP port 53).
B. If you suspect that your firewall is causing DNS issues, you can temporarily disable it to see if that resolves the problem. Remember to re-enable it after testing to maintain your system’s security.
C. If you have third-party security software installed (such as antivirus programs or internet security suites), check their settings for any features related to network traffic filtering or DNS protection. Make sure that DNS traffic is allowed and not being blocked by any security features.
D. Some security software allows you to create whitelists of trusted websites or services. Add your DNS servers to the whitelist to ensure that traffic to and from them isn’t blocked.
E. Ensure that your security software is up to date. Sometimes, outdated software can have bugs or compatibility issues that cause DNS problems. Check for updates and install them if available.
6. Update Network Drivers: Make sure your network drivers are up to date. You can update them manually through Device Manager or download the latest drivers from the manufacturer’s website.
7. Disable Proxy Settings: try disabling it to see if it resolves the DNS issue. Proxy settings can sometimes interfere with DNS resolution.
8. Run Network Troubleshooter: In Windows Os, There is built-in network troubleshooter that can help diagnose and fix network-related problems. Go to Settings > Update & Security > Troubleshoot, then select “Internet Connections” and run the troubleshooter.
9. Reset TCP/IP Stack: Open the command prompt (CMD) as an administrator and type the following commands:
netsh int ip reset
netsh winsock reset
10. Check for Malware: Run a full antivirus scan on your computer to check for malware and remove any infections.
