IPv6 - Addressing Modes

In the computer network terminology, the addressing modes refer to he process of hosting an valid IP address in the network.

IPV6 can provides various types of addressing for the host.

More than one host or the host at closest can be addressed.

Unicast

In this mode, each node is identified and communicated uniquely. The IPV6 packet will contains the both address for the sender and the receiver.

For unicast, the sending of information is sent to the particular node in the network.

The data is being communicated to the single node at a time and it is being forwarded or received as a single point of contact

Multicast

This mode is quite similar to that of the IPV4. This mode will communicate packet to the multiple nodes or group of nodes which are in the list of routers.

For initiating any communication, you need to join the group in that network.

The nodes in the group will receive the information and the rest of the nodes will ignore the information passed from the router

Anycast

This is new kind of addressing known as anycast, in which the multiple interface is communicated with any of the IP address in the network.

In this case, when any host wants to make communication to the other node both needs to use Anycast IP address, and then  the unicast message is sent by the sender to the receiver.
