What is MAC Address?
MAC Address or Media Access Control is a unique and alphanumeric identifier assigned by the NIC (Network Interface Controller) manufacturer and will be stored in the hardware of the device. While IP addresses are assigned by internet service providers and can be re-assigned as devices connect and disconnect, MAC addresses are tied to the physical adapter and cannot be re-assigned. MAC address is very crucial when you want your device to interact with local network devices. When your device detects the router, it sends out its MAC address to start the connection.
