IPV6 CHAPTER 4 IPV6 ADDRESSING MODES

IPV6 Addressing Modes

Unicast 

Multicast

Anycast

Note :- In IPV4 we have  Unicast , Multicast and Broadcast . There is no Broadcast address in IPV6.

Unicast Addressing Mode

Used when one host to one host communication is desired.
Example –Unicast address will be used when Host A wants to communicate with Host B.
                                                                                             
Global Unicast Address
Link-Local Address
Unique-Local Address

Multicast Addressing Mode 

Used when one host to many (a group of hosts) hosts communication is desired.
The multicast information is send on an special multicast address and all the hosts which are in that multicast group receives the information.
Range – FF00::/8
All node on link
Address – FF02::1

Anycast Addressing Mode 

New type of addressing introduced.
It is different from Broadcast.
In this addressing mode, multiple interfaces are assigned with same Anycast IP address.
When a host wishes to communicate with a host equipped with an Anycast IP address, it sends the  message. With the help of complex routing mechanism, that message is delivered to the host closest to the Sender in terms of Routing cost.
