How to Find FQDN (Fully Qualified Domain Name)

When working with computer networks and internet services, finding the Fully Qualified Domain Name (FQDN) of a system or device can be essential. The FQDN provides the complete address of a specific device within a domain, including the host name and domain name. Here is a step-by-step guide on how to find the FQDN:

1. Open the Command Prompt: On Windows, press the Windows key + R, type “cmd” in the Run dialog box, and hit Enter. On macOS or Linux, open the Terminal.

2. Type “hostname” and press Enter: This command will display the host name of your system. Note it down.

3. Type “ipconfig” (Windows) or “ifconfig” (macOS/Linux) and press Enter: This command will display network configuration details.

4. Locate the “IPv4 Address” or “inet” field: Note down the IP address associated with your system.

5. Open a web browser and navigate to an online “Reverse DNS Lookup” tool.

6. Enter the IP address obtained in step 4 into the tool and click “Lookup” or “Submit”.

7. The tool will provide the FQDN associated with the IP address.

8. That’s it! You have successfully found the FQDN of your system.
