Detailed explanation-1: -The ARP Request’s destination was the broadcast MAC address ( ffff. ffff. ffff ). The ARP Request existed for the purpose of resolving Host B’s MAC address, hence the target is Host B.

Detailed explanation-2: -When a device sends an Address Resolution Protocol (ARP) request frame, the destination address is always set to the broadcast MAC address FF:FF:FF:FF:FF:FF. This is because the requesting device does not yet know the MAC address of the other device it wants to communicate with.

Detailed explanation-3: -Why would an ARP frame have a destination MAC address of 00:00:00:00:00:00? In the initial ARP request the IP address is known but the MAC address is not so the MAC address is all zeros.
