What is My Ethernet MAC Address?

The Media Access Control (MAC) address is the physical address of a device that is embedded into the Network Interface Card (NIC). It is a 48-bit unique identifier that plays a crucial role in communicating with other devices over a network. In this article, we will explore what a MAC address is, how it works, and why locating a device using its MAC address can be useful.

What is a MAC Address?

A MAC address is the physical address of a device that enables communication between devices over a network. It is used to identify a device on a local area network (LAN) or wide area network (WAN). The MAC address is embedded into the NIC and consists of 48 bits.

How Does it Work?

When a device wants to communicate with another device over a network, it needs to know the destination MAC address. This information is used to send data packets that contain IP address information. The frames encapsulate these packets, which helps identify the corresponding IP address.

Devices in the data link layer rely on MAC addresses for communication. If you are unable to find the IP address of a device, you can use its MAC address as an alternative. Additionally, if your computer is unable to display its IP due to various reasons, you may receive a 'No Valid IP Address' error.
