Which of the following statement is incorrect?
The Addresses Resolution Protocol, ARP, allows a host to find the physical address of a target host on the same physical network, given only the target IP address.
The sender's IP - to- physical address binding is included in every ARP broadcast; receivers update the IP-to-Physical address binding information in their cache before processing an ARP packet.
ARP is a low-level protocol that hides the underlying network physical addressing, permitting us to assign IP-addresses of our choice to every machine.
