To better understand this, consider a daily Internet usage scenario where you use your mobile phone/computer to request access to a website from your Internet Service Provider (ISP). MAC addresses are used by home/office network devices to identify the devices requesting information and operate them accordingly. In this article, we’ll go over the reasons why you should change MAC addresses, as well as steps to help you change the MAC address of your Mac or Windows computer. However, depending on the operating system and the NIC used, it is possible to spoof (change) the MAC address of a device. A MAC address is a unique physical address/hardware address that is burned/encoded into the NIC (Network Interface Controller) of a device during manufacturing.
Most network interfaces on modern devices, be they smartphones, tablets, computers, or even routers, have a MAC address. The MAC or Media Access Control address is an essential element for communication between devices.
