Fun Fact
A MAC address is 48 bits long, meaning there are over 281 trillion possible combinations-far more than the number of devices that will ever exist on Earth.
Historical Context
MAC addresses were introduced with early Ethernet standards in the 1970s and 1980s to uniquely identify network interfaces. While originally intended to be globally unique, modern networking increasingly relies on locally administered MAC addresses to improve privacy and flexibility.
