Finding the Fully Qualified Domain Name (FQDN) of your Computer

Instructions for finding the Fully Qualified Domain Name (FQDN) of your computer.

Fully Qualified Domain Name (FQDN)

An important understanding is the difference between the hostname, or the name, and the Fully Qualified Domain Name (FQDN) of the computer.

What is the FQDN?

Sometimes you will need to use the Fully Qualified Domain Name (FQDN) of your computer. It is a way of providing more context to the system. It is simply the hostname + suffix. For a PC with the hostname SSCSUPERCOMP the FQDN would be SSCSUPERCOMP.ads.ssc.wisc.edu.

At the SSCC, your suffix is typically *.ads.ssc.wisc.edu or *.ssc.wisc.edu. , depending on the system. The graphic below shows an analogy using a person's name vs fullname and address:

Where to Find the FQDN?

On your Windows PC, follow these steps to find your FQDN:

  1. Launch the Control Panel by searching for "Control Panel" in the Start Menu, or by typing Win+R and typing "control.exe" in the Run menu.
