What do the address resolution protocol (ARP) for IPv4 and the neighbor discovery procedures for IPv6 have in common?

ABoth detect duplicate MAC address assignments.

BBoth detect duplicate IP address assignments.

CBoth resolve a host device's MAC address using its IP address.

DBoth resolve a host device's IP address using its MAC address.

Show Suggested Answer

Suggested Answer: C

ARP for IPv4 and Neighbor Discovery Protocol (NDP) for IPv6 are both used to map a device's IP address to its MAC address. This is essential for communication within a local network.

ARP is used in IPv4 networks, and NDP performs a similar function in IPv6 networks, ensuring devices can communicate effectively on the same network segment.

I’m a bit confused; I thought ARP was only for IPv4. Does that mean it doesn't apply to IPv6 at all?

I feel like there was something about detecting duplicates in both protocols, but I can't recall if it was just for IP addresses or MAC addresses too.

I remember practicing a question about ARP and how it resolves IP to MAC, so I think option C might be the right answer here.

I think both protocols are about resolving addresses, but I'm not sure if they both deal with MAC addresses specifically.
