This content is aligned withIPv4 Addressing Fundamentals, detailed in the FLDTEC course underDevice Configuration and Verification:
Unicast: A unicast address uniquely identifies a single host on anetwork. This is the most common address type used for standard communication between two devices.
Broadcast: Broadcast addresses (e.g., 255.255.255.255 or subnet-specific broadcast) send traffic to all hosts in the network segment. Used for ARP requests and DHCP discovery.
Multicast: Used to deliver a packet to agroup of hostsinterested in the data, without flooding the network like a broadcast. Multicast uses addresses from the range224.0.0.0 to 239.255.255.255.
Loopback: The loopback address (127.0.0.1) is reserved for local testing, ensuring that the TCP/IP stack is working properly without needing to access the network.
