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 leaning towards C too. They both serve the same purpose in different versions.

I agree, C makes sense. It's essential for communication in both IPv4 and IPv6.

I think C is the right choice. Both protocols resolve MAC addresses from IP addresses.

Yeah, but ARP is for IPv4 only, so it's not the same!

I think they also handle duplicate IPs, but not sure.

Both resolve MAC addresses from IPs, right?

I vaguely remember that ARP and neighbor discovery both help in finding addresses, but I can't remember if they resolve MAC or IP addresses specifically.

I feel like both protocols have something to do with detecting duplicates, but I can't recall if it's MAC or IP addresses.

I remember practicing a question that mentioned ARP resolving MAC addresses from IP addresses, so I think option C might be correct.

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