Find MAC Address of a Computer or Printer
A MAC (Media Access Control) address is a unique identifier assigned to a network adapter or network interface card (NIC) by the manufacturer. The MAC Address can also be called the Ethernet Hardware Address (EHA), Ethernet ID, Physical Address, Hardware Address, or Adapter Address. Notebook or laptop computers may have more than one MAC address since they will have Ethernet and wireless NICs installed.
MAC addresses are normally 6 groups of two digits separated either by hyphens (-) or colons (:) or shown just as a 12 digits. Examples: 5C-26-0A-5A-C6-3B, 00:0d:93:64:50:f2, 0030C131739F
