Which traffic type operates within the class D address range?

Class D address range, which spans from 224.0.0.0 to 239.255.255.255, is specifically allocated for multicast traffic. Multicast is a communication model where data is sent from one source to multiple destinations simultaneously, allowing for efficient use of network resources. Rather than sending copies of the data to each recipient (as in unicast), or sending it to all hosts in a network segment (as in broadcast), multicast allows the source to send a single copy of the content that is then distributed to multiple receivers that have expressed interest in that particular multicast group.

This is particularly useful for applications like streaming media or video conferencing, where the same data needs to be delivered to multiple receivers without overwhelming the network. Each multicast group is identified by a specific address within the Class D range, and devices must join these multicast groups to receive the traffic.

In summary, the traffic type that operates within the Class D address range is multicast, which efficiently delivers data to groups of interested receivers.
