How to Identify Devices by MAC Address Online

For each network interface in a device, there is a unique Media Access Control (MAC) address associated with it. This 48-bit address is divided into two parts: the first six digits represent the manufacturer's identifier, and the last six digits represent the Network Interface Controller assigned by the manufacturer.

A device can have multiple MAC addresses, and they are used to identify devices at the data link layer. The MAC address is embedded in the Network Interface Card (NIC), which provides a device with a dedicated connection to a network.

What is a MAC Address?

A MAC address is the physical address of a device that consists of 48 bits. It is used to communicate locally through Ethernet or Wi-Fi, and devices depend on MAC addresses for their communication.

If you are unable to find the IP address of a device, you can resort to using its MAC address. This can be useful in situations where your computer is unable to display its IP due to various reasons, resulting in a 'No Valid IP Address' error.

Why Locate a Device Using a MAC Address?

Locating a device using a MAC address can be useful for several reasons:

* How to locate a device using a MAC address with an IT Asset Management tool

* How to locate a device using a MAC address on macOS

* How to locate a device using a MAC address on Windows

Using a MAC address allows users to access websites without memorizing complex series of characters.

How IP Addresses and MAC Addresses Work Together

Each IP packet contains both the IP address of the device or domain sending the packet, and the IP address of the intended recipient. DNS resolvers translate human-readable domain names into IP addresses.

An IP address is a series of characters, such as '192.168.1.1'. The purpose of an IP address is to handle the connection between devices that send and receive information across a network. Every device on a network has a unique address called an IP address, which helps identify the device and enables other devices to communicate with it.

By understanding how MAC addresses work and how they are used in conjunction with IP addresses, you can effectively locate devices using their MAC addresses online.
