A Media Access Control address or MAC address is a unique code assigned to every piece of hardware that connects to the Internet. Internet capable phones, Network Interface Cards for desktop or notebook computers, Wireless Access Cards, and even some memory cards are among the devices that are assigned MAC addresses.

A media access control address (MAC address), also called physical address, is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet and WiFi. To masquerade (spoof) the identity of a different device. MAC addressing spoofing can be used legitimately to register a home network gateway device with an internet provider. It can also have malicious intent, such as to defeat the MAC address filtering feature to break into the network.

MAC stands for Media Access Control, and, long story short, the MAC address is a code used to identify a particular computer or device on various types of networks, such as Wi-Fi, ethernet, Bluetooth and many more.

When a manufacturer creates a network capable piece of hardware they will assign the MAC address which will usually begin with a code that is tied to the manufacturer. The code will be unique to every device, even two devices of the same type.


A device’s MAC address is composed of six pairs of hexadecimal numbers. The numbers are separated by colons as in the following example:

A lightweight MAC address spoof software for Windows, MadMAC comes with a compact and a moderate graphical user interface. In order to spoof the MAC address you simply need to choose the network card interface, input the MAC address manually and then eventually save the settings to bring the change to the MAC address. Jan 21, 2016  MAC addresses are typically used only to direct packets from one device to the next as data travels on a network. That means that your computer’s network adapter’s MAC address travels the network only until the next device along the way. If you have a router.


MAC addresses are used at the data link layer of the OSI hardware model to allow packets to be passed directly between devices on a network. This helps to ensure that the data is sent to a physical device before being decoded and/or manipulated by a device.

A MAC address is similar to an IP address that the device also receives in that it ensures each device is unique and allows data to be passed among hardware devices. An IP address allows two devices to communicate across a LAN or network environment — normally IP addresses should also be unique and will allow the exchange of data.

Stands for 'Media Access Control Address,' and no, it is not related Apple Macintosh computers. A MAC address is a hardware identification number that uniquely identifies each device on a network. The MAC address is manufactured into every network card, such as an Ethernet card or Wi-Fi card, and therefore cannot be changed.

What Is Iphone Mac Address Used For

Because there are millions of networkable devices in existence, and each device needs to have a unique MAC address, there must be a very wide range of possible addresses. For this reason, MAC addresses are made up of six two-digit hexadecimal numbers, separated by colons. For example, an Ethernet card may have a MAC address of 00:0d:83:b1:c0:8e. Fortunately, you do not need to know this address, since it is automatically recognized by most networks.
