Introduction to MAC

Introduction to MAC

This section describes the definition, background, and functions of MAC.

A Media Access Control (MAC) address defines the location of a network device. A MAC address consists of 48 bits and is displayed as a 12-digit hexadecimal number. The 0 to 23 bits are assigned by IETF and other institutions to identify vendors, and the 24 to 47 bits are the unique ID assigned by vendors to identify their network adapters.

MAC addresses are classified into the following types:

  • Physical MAC address: identifies a device on a LAN. Each physical MAC address is globally unique.

  • Broadcast MAC address: indicates all devices on a LAN. The broadcast address is all 1s (FF-FF-FF-FF-FF-FF).

  • Multicast MAC address: indicates a group of stations on a LAN. All the MAC addresses with the eighth bit as 1 are the multicast MAC address, excluding the broadcast MAC address.
