3. • Internet Protocol version 6 (IPv6) is the most
recent version of the Internet Protocol (IP),
the communications protocol that provides an
identification and location system for computers
on networks and routes traffic across
the Internet..
Introduction

4. IPv6
IPv6 is an Internet Layer protocol for packet-
switched internetworking and provides end-to-
end datagram transmission across multiple IP networks, closely
adhering to the design principles developed in the previous version
of the protocol, Internet Protocol Version 4(IPv4).

5. ∗ Large Address Space.
∗ 128 bit vs. 32 bit in IPv4.
∗ Stateless auto configuration of hosts.
∗ Plug and play.
∗ Multicast.
∗ It is part of IPv6, unlike IPv4 was introduced later.
Features of IPv6

6. ∗ Link-local addresses.
∗ Never change, unlike global address.
∗ Jumbo grams.
∗ IPv4, packets are limited to 64 KB, Jumbo grams can be as
large as 4GB. In high speed Internet.
∗ Network-layer security.
∗ IP Security is built on IPv6, unlike IPv4 built on.
∗ Mobility.
∗ Make IPv6 node to be mobile to change it’s location in an
IPv6 network. (May change IPv6 Address Dynamically).
Features of IPv6

7. ∗ The primary change from IPv4 to IPv6 is the length of network
addresses.
∗ 128 bit vs. 32 bit.
∗ IPv6 addresses are typically composed of two logical parts:
∗ 64-bit (sub-)network prefix.
∗ 64-bit host part. (automatically generated from the interface's
MAC address).
∗ User identity being permanently tied to an IPv6 address.

8. ∗ Kinds of IPv6 addresses:
∗ Unicast Addresses:
∗ One to One.
∗ Multicast Addresses:
∗ One to Many.
∗ Anycast Addresses:
∗ One to Nearest.
∗ There is no Broadcast in IPv6.
IPv6 Addressing

9. ∗ Transition mechanisms are needed for IPv6 only
host to reach IPv4 services.
∗ Dual stack.
∗ Tunneling.
∗ Translation.
Transition Mechanisms

10. IPv4 IPv6
∗ Dual Stack:
∗ Dual stack host can speak both IPv4 and IPv6
∗ communicate with IPv4 host by IPv4
∗ communicate with IPv6 host by IPv6
Transition Mechanisms
Application Layer
Transport Layer (TCP/UDP)
Network Interface Layer

11. ∗ Tunneling:
Transition Mechanisms
IPv6 over IPv4 tunneling
IPv6 Packet
IPv6 PacketIPv4 header
IPv4 Packet
IPv6 Packet

12. ∗ Any modern O/S has IPv6 support
∗ Most common applications and tools have IPv6 support:
∗ Apache
∗ IIS
∗ FTP
∗ Ping
∗ Telnet
∗ IE
∗ Mozilla Firefox
∗ Opera
∗ Outlook
∗ Windows Media Player and more…
∗ Some applications need to be recompiled.
Software Support

13. ∗ Home Networking.
∗ Gaming.
∗ Mobile Devices.
∗ Enterprise PC’s.
∗ Consumer Devices.
∗ i.e. Sony.
∗ ISP.
IPv6 Market

14. ∗ IPv6 is NEW …
– built on the experiences learned from IPv4
– new features
– large address space
– auto configuration
∗ … and OLD
– still IP
– build on a solid base
– started in 1995, a lot of implementations and tests
done
