Traditionally, 12-digit ( 6 bytes or 48-bit) hexadecimal number. Therefore, MAC Address is also called a Networking Hardware Address, Burned-in Address (BIA), Physical Address, or Ethernet Hardware Address. By default, that address is fed into the network hardware during manufacturing by its manufacturer. The Network Adapter or NIC always comes with the MAC Address, hardcoded and stored in its hardware, usually in its ROM (Read Only Memory) or BIOS (Basic Input/Output System). The Media Access Control (sub-layer of the Data-Link Layer (DLC) of telecommunication protocols) uses that address. It identifies the hardware manufacturer and works along with IP Addresses for network communication between devices on the network. Thus, the MAC or Media Access Control Address is a unique identifiable address, usually printed on the network hardware of your key connected device. Here, the software address refers to IP Address, and the hardware address refers to the MAC Address tied with the network hardware of your key connected device called Network Adapter or NIC (Network Interface Card). To communicate between two networked devices, we need network software and hardware. One thing is common in both environments. Like the house with its postal address, every device on the internet has a unique MAC Address that identifies it on the network.Įither working on a wired or a wireless network. And can generate the four most commonly used MAC address formats in upper and lower case for your convenience.

The tool provides the option to specify the custom prefix (OUI). The MAC Address Generator generates the random number of MAC addresses for your testing purposes.
