How Do You Know If A MAC Address is Unicast, Multicast or Broadcast | Tooabstractive

In order to know if a MAC address is a Unicast MAC address, Multicast MAC address or Broadcast MAC address, you need to understand what a MAC address is. A MAC address consist of a 48-bit or 6-byte. As an example - 4A:30:10:19:10:1A But the main point needed in order to identify if a MAC address is a Unicast or Multicast is the first byte. The first byte consists of 8-bits [b7, b6, b5, b4, b3, b2, b1, b0], b7 is the MSB (Most Significant Bit) while b0 is the LSB (Least Significant Bit). If the LSB (b0) is 0 then it is said to be a unicast MAC address but if LSB (b0) is 1 then it is said to be a multicast MAC address. But a broadcast MAC address is generic and does not need to be noted using the LSB or whatsoever because it consist of FF:FF:FF:FF:FF:FF or 1111:1111:1111:1111:1111:1111.
