2023-12-16 13:52:10

The nslookup command is a network administration tool used to query the Domain Name System (DNS) to obtain domain name or IP address information. It is commonly used to troubleshoot DNS-related issues or gather DNS information. Here’s how you can use the nslookup command:

  1. Open a terminal or command prompt:

    • On Windows: Press Win + R, type cmd, and press Enter.
    • On macOS or Linux: Open the Terminal application.
  2. Run the nslookup command followed by the domain name or IP address you want to look up:

    nslookup {{domain or IP address}}
    

    For example, to look up the IP address of example.com, you would run:

    nslookup example.com
    
  3. Review the output:
    The nslookup command will display the results of the DNS query. It typically includes the IP address(es) associated with the domain name, as well as additional information such as the DNS server used for the lookup.

    If you want to perform a reverse DNS lookup (finding the domain name associated with an IP address), you can provide the IP address instead of the domain name:

    nslookup {{IP address}}
    

    For example:

    nslookup 8.8.8.8
    

Note that the nslookup command may have slightly different behavior or options depending on the operating system you are using. It is a powerful tool for DNS troubleshooting and exploration. You can refer to the documentation or the nslookup manual page for more information specific to your operating system.
