Mobile IPv6 is a protocol that allows mobile devices, such as smartphones and tablets, to move between different networks while maintaining a consistent IP address. It works by establishing a tunnel between the mobile node's home network and its current location, allowing traffic to be routed to and from the mobile node.

The three components of Mobile IPv6 are:

  1. Home Agent: The Home Agent is a router on the home network that maintains information about the mobile node's location and serves as a point of contact for communication with the mobile node. It also helps the mobile node establish a tunnel to its current location.

  2. Correspondent Node: The Correspondent Node is any device that communicates with the mobile node. It sends traffic to the Home Agent, which forwards it to the mobile node over the established tunnel.

  3. Mobile Node: The Mobile Node is the device that is mobile and moves between networks. It maintains its IP address regardless of its location and uses the Home Agent to establish a tunnel to its current network. Once the tunnel is established, traffic can flow to and from the mobile node as if it were on its home network.

Therefore, the correct options are A. Home Agent, B. Correspondent Node, and C. Mobile Node.

Option D. Binding Node is not a component of Mobile IPv6.

Option E. Discovery Probe is not a component of Mobile IPv6 either, it may refer to a type of network packet used to discover other devices on the network.
