IPV6 CHAPTER 1 - Introduction to IPV6

•IPv6 stands for Internet Protocol version 6

•IPv6 was developed by the Internet Engineering Task Force (IETF).

•New version of IP Protocol which is in use.

•IPv6 was also called IPng in the early days of IPv6 protocol development stage.

•WHY NOT IPV5 ?

•IPv5 is used for Experimental purposes .

•Known as “Internet Stream Protocol                                                                                             

•Introduction to IPV6

•IPV6 is mainly deployed since already existing IPV4 is running out of addresses .

•IPv4 is 32 bits .

•Provided 2^32 =4294467295 (about 4.3billion) IP addresses.

•For IPV4 Different Techniques were introduced –Subnetting , NAT. But still there will be storage of IP addresses.

                                                                                             

Features of IPV6

•IPV6 is 128 bits.

•Provides 2^128=

340,282,366,920,938,463,463,374,607,431,768,211,456

          340 trillion trillion trillion addresses

•Bigger Address Space as compared to IPV4.

•Using IPV6 we can assign IP address to every possible things.

•NAT not required.

•No Broadcast (Anycast is introduced)

                                                                                             

Features of IPV6

•Header Format is simple as compared to IPV4

•IPv6 contains 6 basic header field whereas IPV4 has 12.

•Faster Processing.

•Inbuilt IPSec (now optional)

•Stateless auto configuration - No more need to configure IP addresses for end devices since Device gets IPV6 address by including its own MAC Address.

•Built-in support for QoS tagging.

•Built-in support for IP Mobile (IP address Mobility)
