This tutorial explains the MAC (Media Access Control) address in detail. Learn what the MAC address is, how it is formed, and the types of MAC addresses (unicast, multicast, and broadcast).
A MAC address (short for medium access control address or media access control address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment.
The Media Access Control (MAC) address is a binary number used to identify computer network adapters. These numbers (sometimes called hardware addresses or physical addresses) are embedded in the network hardware during the manufacturing process or stored in firmware and designed not to be modified.
MAC addresses work with the card in your device that lets it connect wirelessly to the internet, called a Network Interface Controller (NIC). MAC addresses are used to identify which device is which on your local network so that data gets sent to your computer and not your roommate's smartphone.
A MAC address uniquely identifies every device on a network. Learn how to find the MAC address of a device and how it differs from an IP address.
A media access control (MAC) address uniquely identifies digital devices. In fact, a device can have several MAC addresses because devices need a different address for each network interface. For example, although desktops typically only have one MAC address, laptops often have two.
1. Introduction. Nowadays, multiple organizations produce, distribute, and sell network-related hardware, such as wireless or Ethernet cards. Eventually, such hardware will operate on a computer, enabling it to communicate over a network.
In this lesson, we will focus on what is a MAC address, why we use these addresses and mac address examples. We will also learn MAC address lookup on different devices for Cisco IOS, Windows, Linux, IOS, Android etc.
Each network device has a unique MAC address. When we send an Ethernet frame, we add our own MAC address in the source field, and the receiver's MAC address in the destination field of the Ethernet header. The MAC address is 48 bits or 6 bytes in total. We write it in hexadecimal. For example: 0000.0c12.3456
MAC Address is a unique 6-byte (48-bit) address that is usually permanently burned into a network interface card or other physical-layer networking device and that uniquely identifies the device on an Ethernet-based network.
