What is the Layer 3 Broadcast Destination Address?

The Layer 3 Broadcast Destination Address is 255.255.255.255. This address is known as the limited broadcast address and is used in IP networking to send a message to all hosts on the local network. When a packet is sent to this address, all devices within the same broadcast domain will receive and process the packet.

In contrast, addresses like 192.168.0.1 represent a specific host on a network, rather than a broadcast destination. The address 255.255.255.0 refers to a subnet mask and is not used as an address for broadcasting; it indicates the range of addresses within a network. The address 0.0.0.0 is typically used to denote an unknown address or as a default route and does not serve as a broadcast address. Thus, 255.255.255.255 is the correct choice for the Layer 3 broadcast destination, as it fulfills the requirement of sending packets to every device on the local network segment.
