For the initial communication, Host A will send a broadcast ARP (all F’s) to determine the
correct address to use to reach the destination.
ARP sends an Ethernet frame called an ARP request to every host on the shared link-layer
legmen. The Ethernet header includes the source host MAC address and a destination address
of all Fs representing a broadcast frame. The ARP request contains the sender’s MAC and IP
address and the target (destination) IP address. The target’s MAC address is set to all 0s.
