How Do You Check DNS Server Is Working or Not?

Domain Name System (DNS) is a critical component of the internet that translates human-readable domain names into IP addresses. It allows us to access websites by typing in their domain names rather than remembering complex numerical IP addresses.

However, like any other network service, DNS servers can encounter issues that may affect their functionality. In this article, we will explore various methods to check if a DNS server is working or not.

1. Using the Ping Command

Ping is a command-line network utility that helps determine if a specific IP address or host is accessible on the network.

  • Step 1: Open the command prompt or terminal on your computer.
  • Step 2: Type ping followed by the IP address or domain name of the DNS server you want to check.
  • Step 3: Press Enter and wait for the results.

If you receive responses with low latency times, it indicates that the DNS server is reachable and functioning properly.

2. Using the nslookup Command

The nslookup command is another useful tool for checking DNS server functionality and troubleshooting DNS-related issues.

  • Step 2: Type nslookup, followed by the domain name or IP address you wish to query.
  • Step 3: Press Enter and analyze the output.
  • The nslookup command provides detailed information about the queried domain or IP address, including the associated DNS server. If you receive valid responses, it indicates that the DNS server is working correctly.

    3. Using Online DNS Tools

    Several online tools are available to check the status of DNS servers. These tools typically perform queries and provide insights into the server’s response time, validity of records, and other diagnostic information.

    • Step 1: Open a web browser.
    • Step 2: Visit an online DNS checking tool such as DNS Checker, DNSstuff, or UltraTools DNS Lookup.
    • Step 3: Enter the domain name or IP address of the DNS server you want to test.
    • Step 4: Click on the “Check” or “Lookup” button to initiate the test.

    The online tool will display various details about the DNS server’s status, allowing you to assess its functionality.

    4. Checking Network Configuration

    If you encounter persistent issues with multiple DNS servers, it is essential to examine your network configuration.

    • Step 1: Ensure that your computer’s network settings are correctly configured to use a specific DNS server.
    • Step 2: Verify that there are no conflicting settings or firewall rules blocking access to DNS servers.
    • Step 3: Restart your networking equipment, such as routers or modems, to refresh the network connections.

    By carefully reviewing and adjusting your network configuration, you can resolve potential issues that may affect DNS server functionality.


    In this article, we have explored several methods to check if a DNS server is working or not. By using the ping and nslookup commands, along with online DNS tools, you can assess the server’s reachability and response.

    Additionally, reviewing your network configuration is crucial to resolving any underlying issues. Regularly monitoring DNS server functionality ensures a smooth internet experience and helps troubleshoot connectivity problems efficiently.
