MAC Address is a unique 6-byte (48-bit) address that is usually permanently burned into a network interface card (NIC) or other physical-layer networking device and that uniquely identifies the device on an Ethernet-based network. The original IEEE 802 MAC address comes from the original Xerox Network Systems Ethernet addressing scheme. This 48-bit address space contains potentially 2 48 (over 281 trillion) possible MAC addresses. The IEEE manages allocation of MAC addresses, originally known as MAC-48 and which it now refers to as EUI-48 identifiers.

What's the difference between a MAC address and IP address? By: John 2020-03-31 · MAC address also known as physical address is the unique identifier that is assigned to the NIC (Network Interface Card) of the computer. NIC helps in connection of a computer with other computers in the network. MAC address is unique for all the NIC’s.

[a] The internal structure of an Ethernet frame is specified in IEEE 802.3. [1] The special address of all zeros (as shown below) is reserved for nodes that currently have no configured MAC address: 00 00 00 00 00 00 The IEEE-assigned addresses allow each vendor to assign their own interface serial numbers (this is a flat addressing scheme), but also allows protocol monitors to examine the first 3 bytes of a frame address to determine the manufacturere of the interface If not then many linksys routers allow you to create a new MAC address. AFAIK a MAC address is in the physical device, it's a combination of a manufacturer ID with some other data selected by him ( date, model , etc ), it's required to be unique cheers,--Ignacio Machin, ignacio.machin AT dot.state.fl.us Florida Department Of Transportation These addresses are 48 bit (6 bytes) long and are written in hexadecimal notation.
