Show Suggested Answer Hide Answer
Suggested Answer: A 🗳️
ARP interrogates the network by sending out a broadcast seeking a network node that has a specific IP address, and asks it to reply with its hardware address. A broadcast message is sent to everyone whether or not the message was requested. A traditional unicast is a "one-to-one" or "narrowcast" message. A multicast is a "one-to-many" message that is traditionally only sent to those machine that requested the information. Semicast is an imposter answer.
