Evaluation of address resolution protocol and essential security issues

An internet consists of various types of network and connecting devices like router. A packets starts from the source host, passes through many physical network and finally, reaches the destination host. At the network level, the routers are recognized by their IP address. The main limitation of ARP is traffic jam in nodes due to unless point to point communication. ARP Request is point to point communication which packet doesn't contain hardware address of receiver per as my research when a packet extend it content and include the hardware address it can maintain point to point communication with the nodes(machine). ARP Reply includes point to point in network, as my research the packet reply at broadcasting to every node which copy the sender and receiver hardware address. As per research, the COUNT helps to check the no of nodes viewed the packet.
