A Media Entry Management tackle (MAC tackle) is a novel identifier assigned to a community interface controller (NIC) to be used as a community tackle in communications inside a community section. MAC addresses are utilized in most IEEE 802 networking applied sciences, together with Ethernet, Wi-Fi, and Bluetooth. A MAC tackle is a 48-bit quantity that’s usually written in hexadecimal format, similar to 00:11:22:33:44:55.
MAC addresses are necessary for a number of causes. First, they permit community units to determine one another on a community. Second, they can be utilized to manage entry to a community. For instance, a community administrator can configure a router to solely permit units with particular MAC addresses to connect with the community. Third, MAC addresses can be utilized to trace the motion of units on a community. For instance, a community administrator can use a software referred to as a MAC tackle tracker to see which units are linked to a community and the place they’re positioned.
