Best answer 27 27 votes The address resolution protocol (ARP) is a protocol used by the Internet Protocol (IP) specifically IPv4, to map IP network addresses to the hardware addresses used by a data link protocol. So option D is correct.

1 1 vote The correct answer is 4 (or D): Finding the MAC address that corresponds to an IP address.ARP is used by the Internet Protocol (specifically IPv4) to map an IP network address to the physical hardware (MAC) address used by the data link protocol.As a quick heads-up for your GATE 2027 prep, keep in mind that IP support protocols like ARP have actually been removed from the 2027 syllabus, so you can safely avoid spending too much time on this specific area.
