![]() ![]() The MAC address is divided into 6 octets, whereas an octet consists of 8-bits. The famous well-known manufacturer ID is: And the remaining 24-bits 9d6816 is the serial number of the adapter. The first 24-bits that is 001422 is the manufacturer ID. The next 24-bits of the MAC address is the serial number assigned by the manufacturer to the network adapter.įor instance, let support the MAC address of the network adapter is 00:14:22:9d:68:16. The manufacturer ID is regulated by internet standard IEEE 802. The first 24-bits of the MAC address is the ID number of the NIC manufacturer. ![]() The MAC address has the following format: How is the MAC address represented?Ī MAC address consists of a 12-digit hexadecimal number, which is 48-bit in length. The example of Ethernet NIC MAC address is 00:0a:95:9d:68:16. Moreover, the Address Resolution Protocol (ARP), which is a communication protocol of the Network Layer, is used to discover a MAC address associated with an IP address. So, a MAC address is sometimes also called a link-layer address. MAC addresses participate in networking and are used by the Media Access Control Protocol, the sub-layer of the Data Link Layer of the OSI reference model. It stores the address most often in read-only memory, and other mechanisms depending on the manufacturer.īecause of this reason, the MAC address is sometimes called a burned-in address (BIA), physical address, or networking hardware address. MAC address is often assigned to your Network Interface Card (NIC) by the device manufacturer, and it is hard-coded on your NIC. The network interface card (NIC), added to your computer, has a MAC address.Ī MAC (Media Access Control) address acts as a unique identifier assigned to your Network Interface Card (NIC) for communication in a network. The NIC work is to turn data into an electrical signal that can be transmitted over the network. NIC’s other name is a network adapter, LAN adapter, Ethernet card, or physical network interface. A hardware address identifies the hardware connected in a network and is typically known as Network Interface Card or NIC.Ī Network Interface Card is a hardware component, typically a circuit, board, or chip, which is the necessary equipment needed for your computer to connect to a network. ![]()
