In the Gratuitous ARP packet, the "Sender protocol address" and "Target protocol address" are filled with the same source IP address
itself. The "Sender H/W Address" and "Target H/W address" are filled with the same source MAC address. The destination MAC
address is the Ethernet broadcast address (FF-FF-FF-FF-FF-FF). All nodes within the network will immediately update their own
ARP table in accordance with the sender's MAC and IP address. The format of Gratuitous ARP is shown in Table-5.
