What is the purpose of the broadcast MAC address?
A broadcast address is a network address used to transmit to all devices connected to a multiple-access communications network. A message sent to a broadcast address may be received by all network-attached hosts.
How are MAC addresses used in networks?
The MAC address (short for media access control address) is the worldwide unique hardware address of a single network adapter. The physical address is used to identify a device in computer networks. Since MAC addresses are assigned directly by the hardware manufacturer, they are also referred to as hardware addresses.
What is an example of a broadcast MAC address?
When the IPv4 broadcast packet is encapsulated in the Ethernet frame, the destination MAC address is the broadcast MAC address FF-FF-FF-FF-FF-FF in hexadecimal (or 48 1s in binary). DHCP for IPv4 is an example of a protocol that uses Ethernet and IPv4 broadcast addresses.
What is a broadcast address used for?
A broadcast address is an IP address that is used to target all systems on a specific subnet network instead of single hosts. In other words broadcast address allows information to be sent to all machines on a given subnet rather than to a specific machine.

In a network, the first address field is reserved for the network and the last for the broadcast address.
Are MAC addresses really unique?

What are MAC addresses used for?
A MAC address is a unique identifier that is assigned to each physical network interface on a computer. Different than a computers IP address, MAC addresses are frequently used for network access control and to monitor network connectivity, and they can be spoofed for virtualization needs or to circumvent some network limitations.
