IPv6 is the next generation internet protocol that replaces IPv4. It features a 128-bit address space compared to IPv4's 32-bit addresses, allowing for vastly more possible IP addresses. IPv6 was developed in the 1990s in anticipation of IPv4 running out of available addresses. It introduces features like built-in security, auto-configuration, and support for new technologies. IPv6 is now incorporated into modern internet-enabled applications and operating systems.

2. INTRODUCTION:
• The present version of the Protocol we are using is the
Internet Protocol version 4, which is successful for many of
the applications on the Internet. But with the latest trends
in the technology we are about to get yet another version
of the World Favorite Protocol which is the version 6. Yes,
with the help of science and technology we have got a new
solution to Ipv4 and probably its successor in the near
future called INTERNET PROTOCOL Version 6 which is the
topic of discussion below. It will change the entire meaning
of Internet connecting itself with the upcoming
technologies such are Internet2 and Quality Of Service
(QoS). Let’s see about this version in detail now.

3. WHAT’S IPV6?
• IPv6 is short for "Internet Protocol Version 6". IPv6 is
the "next generation" protocol designed by the IETF
to replace the current version Internet Protocol, IP
Version 4 ("IPv4").

4. HISTORY
• The current version of the Internet Protocol IPv4 was
first developed in the 1970s, and the main protocol
standard RFC 791 that governs IPv4 functionality was
published in 1981.
• With admirable foresight, the Internet Engineering
Task Force (IETF) initiated as early as in 1994, the
design and development of a suite of protocols and
standards now known as Internet Protocol Version 6
(IPv6), as a worthy tool to phase out and supplant
IPv4 over the coming years.

5. • IPv6 uses a128-bit address size compared with the
32-bit system used in IPv4 and will allow for as many
as 3.4x1038 possible addresses, enough to cover
every inhabitant on planet earth several times over.
The 128-bit system also provides for multiple levels
of hierarchy and flexibility in hierarchical addressing
and routing, a feature that is found wanting on the
IPv4-based Internet.

6. IPV6 FEATURES
• Large address space
• Efficient and hierarchical addressing and routing
infrastructure
• Built-in security
• Extensibility

7. How IPv6 Work
• Internet Protocol version 6 (IPv6) is a networking
protocol that allows Windows users to communicate
with other users over the Internet. It interacts with
Windows naming services such as Domain Name
System (DNS) and uses security technologies such as
Internet Protocol security (IPSec), because they help
facilitate the successful and secure transfer of IP
packets between computers.

9. IPV6 ADDRESSING :
• The most dramatic change from IPv4 to IPv6 is the
length of network addresses. IPv6 addresses, as
defined by RFC 2373 and RFC 2374, are 128 bits long;
this corresponds to 32 hexadecimal digits, which are
normally used when writing IPv6 addresses, as
described in the following section.
The number of possible addresses in IPv6 is 2128 ≈ 3.4
x 1038

10. IPV6 HEADER:
• The most important and the only working part of any
protocol is its HEADER. Without a Header any
Protocol is useless. And thus its description and
explanation is mandatory. The figure shown below is
the IPV6 Header, which is much more simplified than
its previous one.

TECHNOLOGIES
• AUTO CONFIGURATION:
• SECURITY:
• FRIENDLY TO TRAFFIC ENGINEERING
TECHNOLOGIES:
• MULTICAST:

13. IPv6 applications
• The Windows Server 2003 family includes the
following IPv6-enabled applications and
components:
• FTP client
The File Transfer Protocol (FTP) client, Ftp.exe, can be
used to establish FTP sessions with IPv4 and IPv6 FTP
servers.
• Telnet client
The Telnet client, Telnet.exe, can be used to establish
Telnet sessions with IPv4 and IPv6 Telnet servers.

14. ADVANTAGES
• As compared to IVP4 it has Larger Address Space
• It has better header format as compared to IPv4.
• IPv6 has been designed in a way that a protocol
can be extended simply to meet up the
requirements of new upcoming technologies.
• IPv6 provides better resource allocation support
than IPv4.
• It is more secure when compared to IPv6.

15. DIFFICULTIES AND ERRORS IN IPV6
• Incompatability
• Incoherence
• Distractions

16. CONCLUSION:
• IPV6 the latest version of IP series is going to set
trends and make waves in the industry as its
predecessors. IPV6 is having easy configuration,
larger address bits, larger data transmission
capacities and also supports a large number of users
with its addressing scheme. It is having a simpler
header than IPV4
• It will be the biggest boon to the heavily populated
countries like the one of ourselves.
