How to Check DNS Server: A Comprehensive Guide
In today’s digital age, DNS (Domain Name System) servers play a crucial role in translating human-readable domain names into IP addresses that computers can understand. However, it’s essential to ensure that your DNS server is functioning correctly and providing accurate results. This article will provide a comprehensive guide on how to check your DNS server, covering various methods and tools to help you diagnose and resolve any issues that may arise.
1. Using Command Prompt (Windows)
If you’re using a Windows operating system, you can easily check your DNS server by using the Command Prompt. Here’s how to do it:
1. Press the Windows key + R to open the Run dialog box.
2. Type “cmd” and press Enter to open the Command Prompt.
3. In the Command Prompt, type “ipconfig /all” and press Enter.
4. Look for the “DNS Servers” section in the output. This will display the IP addresses of your DNS servers.
2. Using Terminal (Mac and Linux)
For Mac and Linux users, you can check your DNS server using the Terminal. Here’s how to do it:
1. Open the Terminal on your Mac or Linux machine.
2. Type “cat /etc/resolv.conf” and press Enter.

2. Flush your DNS cache by using the “ipconfig /flushdns” command on Windows or “sudo systemd-resolve –flush-caches” on Linux.
3. Temporarily change your DNS server to a public DNS service like Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1 and 1.0.0.1) to rule out any issues with your current DNS provider.
4. Check for any network connectivity issues between your device and the DNS server.
5. Contact your ISP or DNS provider for assistance if the problem persists.
By following this comprehensive guide, you should now have a clear understanding of how to check your DNS server, ensuring that it’s functioning correctly and providing you with accurate results.
