WebStore often will register your computer by its computer name. Each computer possesses a Computer name that is otherwise known as a "Hostname". This label is easier for humans to read and identify than a series of numbers.

Hostname: A human-readable label that serves as the name of your PC or server.

Below you will find the steps to identifying the hostname of your computer. 

Find the hostname in Windows

1: Right-click the Start Menu and select "System"

2: Scroll down and look for the Device name in the About Section. This is your computer name or "Hostname". The Full device name is sometimes needed if you are registering your computer to a local License Manager on campus like Ansys or Comsol. 

Alternate method using the Command Prompt

1: Click Start, and search for cmd. Right-click and select run as administrator. If prompted, confirm yes.

C:\WINDOWS\system32>ipconfig /all

Find the hardware address in Windows

Computers will also have unique hardware addresses to identify the device on the network. The MAC (Media Access Control) address is the hardware address of a network interface and is often referred to as the "Physical Address". It can also be referred to as a "Host ID" or "Server ID".  The address format is a 12 character hexidecimal number which combines numbers (0–9) and letters (A–F, a–f). Your physical address is often presented in this format: XX-XX-XX-XX-XX-XX.

1. Press the Start button, type CMD, then press Enter to start up a command shell
2. Type "ipconfig /all"
3. The hardware address will be listed under "Physical Address"
