•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)
