How to get the Network Address (MAC address) of a Network Adapter

What is a Network Address?

Every Network Adapter has a unique Network Address. We sometimes need you to provide the Network Address to facilitate connection to the Trinity data networks. For example, if you want to connect a new computer to the staff wired network, we will need the Network Address of the Wired Network Adapter. If you are connecting a laptop, we will also need the Network Address of the Wireless Adapter.

Network address always consists of 12 characters. It is usually presented in hexadecimal format. This means that it may contain numbers 0-9 and letters A-F. It is often presented with hyphens, you can omit them.

On a standard PC from an official Trinity supplier, the Network Address is usually located on a label attached somewhere on the machine. If you cannot find it, or you have a non-standard device, you can obtain the network address using instructions below.

How to check the Network Address?

Brand new computers - first time boot

If you have purchased a brand new staff computer and need to find out the MAC (Network Address), in order to submit the Network Request form, you can do the following:

If your Windows computer has been shipped from our preferred supplier, then there will be a sticker on the casing of the computer with the MAC addresses on it.





If your Mac computer has been shipped from our preferred supplier, then there will be a label on the computer packaging with details of the MAC addresses.

The wired MAC address will be listed beside 'Ethernet ID' and the wireless MAC address will be listed beside 'AirPort ID'.

If you no longer have the packaging, you can follow the below steps instead.

  1. Boot Up the Mac: Start your Mac and go through the initial setup steps until you reach the "Welcome" screen (the screen where you choose your country).
  2. Open Terminal by pressing Command (⌘) + Option (⌥) + Shift + T at the same time. Then type ifconfig and hit enter.
  3. The MAC address is listed under the 'en0' section beside 'ether'. In the case below it would be 00:16:cb:cd:3b:4d



    • If the computer is a desktop like an iMac or Mac Pro, then 'en0' will be the wired MAC address and 'en1' will be the Wi-Fi MAC address
    • If the computer is a MacBook, then 'en0' will be the Wi-Fi MAC address. MacBooks don't have wired network ports.
