IPv6 Neighbor Discovery

There is no ARP in IPv6. Instead it uses ICMPv6 for Neighbor Discovery via the Neighbor Discovery Protocol. Please watch the following video and document everything in your blog.

The Neighbor Discovery Protocol (NDP) is an alternative of the the ARP (Address Resolution Protocol).
It's a Protocol in IPv6. It's responsible for the exchange of link-local messages.
It's also being used to determine IPv6-addresses into Link-Layer-Addresses (MAC).
A protocol, which is used for this is "ICMP" (Internet Control Message Protocol).
The process uses multicast addresses to determine the link-layer-address of a neighbor on the same network(local link), verify the reachability of a neighbor and track neighboring devices.

Answer the following questions:

•  What's the "host autoconfiguration"?

A IPv6-Host can create automatically a link-local & a global address.

• Which ICMPv6 types are used for neighbor discovery?

 Router Solicitation (Type 133), Router Advertisement (Type 134), Neighbor Solicitation (Type 135), Neighbor Advertisement (Type 136)

• What is a "tentative address" and what is it used for?

A IPv6-address can have many different states. One of them is the state "tentative" (dt.: vorläufig).
In this state, the address isn't definitely assigned to the interface.
The interface is in a state, where the IP-address is going to be tested.
A point cannot communicate over a tentative address in the network.

• Which kind of IPv6-address is "FF02::1"?

The link-local address
