Don’t know what a MAC address is?

In computer networking, a Media Access Control address (MAC address) is a unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for identification, and used in the Media Access Control protocol sub-layer. If assigned by the manufacturer, a MAC address usually encodes the manufacturer’s registered identification number. It may also be known as an Ethernet Hardware Address (EHA), hardware address, adapter address, or physical address. - Via Wikipedia
