+The first three numbers are to identify the manufacturer, the last 3 numbers are for the ID of the device. In a layer 3 network (most networks now) we generally use the IP Address of the device, but in purely Layer 2 networks then the MAC addresses are used.

+==== Getting the Pico MAC Address ====
+\\
+As with most things Pico/Network we need a Python script. See an example below:
+<code:python | download>
+import network
+import ubinascii
+wlan = network.WLAN(network.STA_IF)
+wlan.active(True)
+print(ubinascii.hexlify(wlan.config('mac'), ':').decode())
+</code>
+Save the above code to your Pico as <color #22b14c>find-mac-address.py</color>
+\\
+\\
+When you run the code in Thonny, you will see something similar to below.
+\\
+\\
+{{ :pico-find-mac-address.png?800 |}}
+\\
+As can be seen, the code outputs the Pico MAC Address in to the shell window in Thonny.
