COMPUTER NETWORKING

Detailed explanation-1: -Unsourced material may be challenged and removed. MAC spoofing is a technique for changing a factory-assigned Media Access Control (MAC) address of a network interface on a networked device. The MAC address that is hard-coded on a network interface controller (NIC) cannot be changed.

Detailed explanation-2: -The MAC address of a WiFi device is hard-coded at the hardware level, so it can’t really be changed (imagine that it’s the serial number of your network adapter). But, that doesn’t mean that it’s not possible to trick the OS into believing that the MAC address is different, hiding the true, hard-coded MAC address.

Detailed explanation-3: -MAC addresses are implemented by software. A NIC only needs a MAC address if connected to a WAN. The first three bytes are used by the vendor assigned OUI. The ISO is responsible for MAC addresses regulations.

Detailed explanation-4: -It stands for Media Access Control, and also known as Physical address, hardware address, or BIA (Burned In Address). It is globally unique; it means two devices cannot have the same MAC address.
