What is the name of the protocol used with IPv6 to learn the Layer 2 addresses that exist on the same local network

Network Discovery Protocol (NDP)

Explanation:

An IP address is an acronym for internet protocol address and it can be defined as a unique number assigned to a computer or other network devices, so as to differentiate each device from one another in an active network system. Thus, an IP address is typically used to uniquely identify each computer or network devices connected to the internet or network.

In Computer networking, IP address are classified into two (2) main categories and these are;

1. Local (internal) IP address.

2. Global (external) IP address.

Also, the internet protocol (IP) address comprises of two (2) versions and these are;

I. Internet protocol version 4 (IPv4): this is the first and original version of the internet protocol which was introduced in 1983 using the Advanced Research Projects Agency Network (ARPANET). An example of an IPv4 address is 192.168.1.0.

II. Internet protocol version 6 (IPv6): it is the modified (latest) version of the IPv4 address system and as such can accommodate more addresses or nodes. An example of an IPv6 is 2001:db8:1234:1:0:567:8:1.

Hence, Internet protocol version 6 (IPv6) was developed and introduced to replace the previous version (IPv4); Internet protocol version 4. The best statement which describes a benefit of IPv6 over IPv4 is that, Internet protocol version 6 (IPv6) eliminates the use of hierarchy in addressing, making addresses easier to use because the size of the routing table is smaller (reduced) and as such making routing with IPv6 to be more efficient.

Hence, Network Discovery Protocol (NDP) is the name of the protocol used with IPv6 to learn the Layer 2 addresses that exist on the same local network.
