Anytime a host or a router has an IP datagram to send to another host or router, it has the (71) address of the receiver. This address is obtained from the DNS if the sender is the host or it is found in a routing table if the sender is a router. But the IP datagram must be (72) in a frame to be able to pass through the physical network. This means that the sender needs the (73) address of the receiver. The host or the router sends an ARP query packet. The packet includes the physical and IP addresses of the sender and the IP address of the receiver. Because the sender does not know the physical address of the receiver, the query is (74) over the network. Every host or router on the network receives and processes the ARP query packet, but only the intended recipient recognizes its IP address and sends back an ARP response packet.The response packet contains the recipient's IP and physical addresses. The packet is (75) directly to the inquirer by using the physical address received in the query packet.
