How Do I Resolve a DNS Name Server?
Resolving a DNS name server issue is essential for ensuring that your website or application can be accessed by users. In this tutorial, we will explore the steps to resolve a DNS name server problem and get your website up and running smoothly.
Step 1: Check Your Internet Connection
Before diving into troubleshooting the DNS name server, it’s important to ensure that your internet connection is stable. A weak or intermittent connection can cause issues with resolving DNS names.
Make sure you are connected to the internet and try accessing other websites to verify the connection.
Step 2: Clear Your DNS Cache
Sometimes, the issue lies within your computer’s DNS cache. Clearing the cache can help resolve any conflicts or outdated entries. To clear the DNS cache, follow these steps:
- Open Command Prompt by pressing Windows key + R, type
cmd, and hit Enter.
- In the Command Prompt window, type
ipconfig /flushdns, and press Enter.
- Open Terminal from Applications > Utilities > Terminal.
sudo killall -HUP mDNSResponder, and press Enter.
- Open Terminal.
- Type one of these commands based on your Linux distribution:
sudo /etc/init.d/nscd restart
sudo /etc/init.d/dnsmasq restart
sudo service network-manager restart
- Mobile Devices:
- On your mobile device, go to the Wi-Fi settings.
- Find your connected Wi-Fi network and tap on it.
- Select “Forget Network” or “Renew Lease” option.
- Open Control Panel and go to Network and Internet > Network and Sharing Center.
- Select your active network connection, then click on “Properties”.
- In the Networking tab, select “Internet Protocol Version 4 (TCP/IPv4)” and click on “Properties”.
- Select “Use the following DNS server addresses” option..
- Preferred DNS server: 8.8.8
- Alternate DNS server: 8.4.4
- Click “OK” and restart your computer.
- Open System Preferences and go to Network.
- Select your active network connection.
- DNS server: 8.8, 8.4
- Click “Apply” and close the Network preferences.
After clearing the DNS cache, try accessing your website or application again to see if the issue is resolved.
Step 3: Change Your DNS Servers
If clearing the DNS cache didn’t resolve the issue, you can try changing your DNS servers. Sometimes, using a different DNS server can provide a more reliable and faster connection. Follow these steps to change your DNS servers:
Note: You can use other public DNS servers like Cloudflare’s 1.1.1 or OpenDNS’ 18.104.22.168 and 208.220.220 if you prefer.
Step 4: Contact Your Internet Service Provider (ISP)
If none of the above steps resolved the DNS name server issue, it’s possible that the problem lies with your internet service provider (ISP). Contact your ISP’s technical support and provide them with detailed information about the issue you are facing. They will be able to assist you further in resolving the problem.
By following these steps, you should be able to resolve most DNS name server issues and ensure that your website or application is accessible to users. Remember to check your internet connection, clear your DNS cache, change DNS servers if necessary, and contact your ISP for assistance if needed. Happy troubleshooting!
