ARP
ARP is address resolution protocol. ARP helps user get the MAC address of a device through its IP address.
Under TCP/IP network environment, each host is assigned with a 32-bit IP address, but MAC address
needs to be known for message transmission in the physical network. ARP is a tool that converts IP
address into MAC address.
