The MAC address generally remains fixed and follows the network device, but the IP address changes as the network device move from one network to another.MAC addressing works at the data link layer, IP addressing functions at the network layer (layer 3).

But Ethernet frames canвЂ™t travel between networks. Each station has a unique MAC address that is used to identify who is the sender (source address) and who the receiver (destination address) is. MAC addresses are used to send Ethernet frames between two stations in the same local area network.

The second half ( 24 MORE BITS) of a MAC address represents the serial number assigned to the adapter by the manufacturer.ДЇor example, consider a network adapter with the MAC address вЂњ00-A0-C9-01-23-45.вЂќ The OUI for the manufacture of this router is the first three octets-вЂќ00-A0-C9вЂі вЂ“ In this case Intel corporation. These IDs are regulated by an Internet standards body (see sidebar). The first half ( 24 BITS) of a MAC address contains the ID number of the adapter manufacturer. MM:MM:MM:SS:SS:SS or MMMM-MMSS-SSSSВ format By convention, MAC addresses are usually written in one of the following formats: LetвЂ™s try to understand the MAC address format with the help of the image given below.ДЄs shown in the above diagram, MAC addresses are 12-digit hexadecimal numbers (48 bits in length). All three numbering systems use the same format and differ only in the length of the identifier. This 48-bit address space contains potentially 281,474,976,710,656 possible MAC addresses. The original IEEE 802 MAC address comes from the original Xerox Ethernet addressing scheme. HOW MANY MAC ADDRESSES CAN THERE BE IN THE WORLD? The ARP takes data from an IP address through an actual piece of computer hardware. It is hardwired or hard-coded onto your computerвЂ™s network interface card (NIC) and is unique to it.ДЄRP (Address Resolution Protocol) translates an IP address into a MAC address. The MAC address is sometimes referred to as a networking hardware address, the burned-in address (BIA), or the physical addressДЄ MAC address is given to a network adapter when it is manufactured. The MAC address is used by the Media Access Control sublayer of the Data-Link Layer (DLC)В of telecommunication protocols.Д®very NICВ (also called LAN card) has a hardware address thatвЂ™s known as a MAC, for Media Access Control.
