+==== MAC Addresses ====
+Written in hexadecimal notation, composed of 12 digits, the first 6 correspond to the **O**rganizational **U**inque **I**dentifier (**OUI**) and the last 6 are given by the manufacturer to each device. Every MAC address should be **unique**.
+Large manufacturers may have many several OUI.
