Final answer:
ARP (Address Resolution Protocol) is not limited to Ethernet MAC addressing alone; it also supports other network technologies in mapping IP addresses to MAC addresses.
Step-by-step explanation:
The statement that ARP is a standard protocol that only addresses IP to Ethernet MAC addressing is false. ARP, which stands for Address Resolution Protocol, is indeed a crucial component of the networking process that links IP addresses to MAC addresses. However, ARP is not limited only to Ethernet; it can also support other types of network technologies. ARP's main function is to translate 32-bit IP addresses to the 48-bit MAC addresses that are used for local network communications, thus enabling data packets to be delivered to the correct device on a local area network (LAN).
