The destination address used for broadcast communication in a network is 255.255.255.255. This address is known as the limited broadcast address. When a packet is sent to this address, it is delivered to all hosts on the local network segment. This is crucial for scenarios where a device needs to communicate with all other devices without knowing their individual IP addresses.

Broadcasting is widely used in various network protocols and services, such as DHCP (Dynamic Host Configuration Protocol), where a client may use the broadcast address to request an IP address from any available DHCP server in the local network.

The other addresses mentioned have specific purposes that do not relate directly to broadcast communications. For example, 192.168.1.255 is a directed broadcast address for the 192.168.1.0 subnet, while 10.0.0.1 is a valid unicast address, typically assigned to a device on the network. The address 0.0.0.0 represents an unspecified address, often used in routing to indicate the default route or as a placeholder before an actual address is assigned.
