Which protocol assists in the resolution of IPv6 addresses to MAC addresses?ARPv6DHCPv6ICMPv6UDPv6

The protocol that assists in the resolution of IPv6 addresses to MAC addresses is Neighbor Discovery Protocol (NDP), which is part of ICMPv6. While ICMPv6 itself is a broader protocol for Internet Control Message Protocol for IPv6, the actual functionality related to address resolution utilizes NDP messages for this purpose.

In this context, here's a breakdown of the options:

1. ARPv6: This is not a standard protocol; ARP (Address Resolution Protocol) is for IPv4. Although IPv6 has its method for address resolution, it doesn't use ARP.

2. DHCPv6: This protocol is used for assigning IPv6 addresses and managing configuration settings, not for address resolution.

3. ICMPv6: While ICMPv6 is indeed used in the IPv6 protocol suite for various functions, including error messages, its subsidiary function of NDP is specifically designed for address resolution and related tasks.

4. UDPv6: User Datagram Protocol (UDP) is a transport layer protocol and is not involved in address resolution processes.

Final Answer

The correct choice is ICMPv6, which facilitates the Neighbor Discovery Protocol for resolving IPv6 addresses to MAC addresses.
