Explanation:
ARP is not used in IPv6 networks.
The Address Resolution Protocol (ARP) is a telecommunication protocol used for resolution of network layer
addresses into link layer addresses, a critical function in multiple-access networks. ARP is used for converting
a network address (e.g. an IPv4 address) to a physical address like an Ethernet address (also named a MAC
