Introducing IPv6 What is IP?

• Vehicle of the Internet- the “Internet Protocol”. • Assigns an address to a device so that it can communicate with other similar internet devices. • IP Address- encoding Network Number and Host Number- a unique combination. • A Network Layer Protocol, it provides internetworking. • IPv4- the present version of the Internet Protocol, is in use since 1982.

IPv6 • IPv4 started showing up problems. • It was not designed to handle the kind of traffic it experienced. • IP had no choice but to evolve and become more flexible. • IETF started work on a new version of IP in 1990. • Final Specification drafted in December 1998. • IPv6 meets the goals set for it by IETF fairly well. • Although not compatible with IPv4, it works smoothly with other auxiliary internet protocols.

IPv6 Some Features • • • • • •

IP Address: 16 bytes long Header: simplified, contains only seven fields Options: better for options Jumbograms: s jumbo-payload option Security: IPSec implemented in IPv6 Quality of Service: Better than before

IPv6 Address

The Main IPv6 Header

Why IPv6? Shortcomings of IPv4 • Designed by DARPA, as a test of its networking capabilities. • The 4.3 billion address space is on verge of exhaustion. • Classful Addressing • The implementation of CIDR and NAT has brought along other problems. • Security • Near-obsolete Header

Why IPv6? IPv6- Need of the Hour • • • • • • • • •

Longer Addresses- 16 byte addresses- inexhaustible Not everyone is connected yet Simplifies Address Assignment Security features Simplified Processing by Routers Mobility without renumbering Better options in Header Globally unique addresses New-age applications

Why IPv6? Transformations • Evolution of LTE as technology of future • Encryption and Authentication in Network Layer itself • IP Telephony, Interactive Gaming and other Audio/Video Applications • Built-in Multicasting • An all-new range of Machine to Machine Applications • IP Host Mobility

Motivations for IPv6 Deployment Stateless Address Auto configuration Large Subnet Size Multicasting Improved Security Simplified Router Processing IP Host Mobility can usher in new services like:  Enterprise on the move  Globally reachable Home Networks  Internet-enabled Transport • Jumbograms- a boon for Supercomputing • • • • • •

Drivers and Catalysts for Change

Migration from IPv4 to IPv6

Dual IP Stack Implementation

Tunnelling

Tunnelling • Automatic Tunnelling  6to4  Teredo  ISATAP • Configured and Automated Tunnelling (6in4)

Proxying and Translation for IPv6-only Hosts

IPv6 Initiatives Around the World World IPv6 Day The Internet Society promoted June 8, 2011, as "World IPv6 Day". The event was described as a "test drive" for full IPv6 rollouts.

World IPv6 Launch Day The Internet Society declared June 6, 2012 to be the date for "World IPv6 Launch", with participating major websites enabling IPv6 permanently, participating ISPs offering IPv6 connectivity, and participating router manufacturers offering devices enabled for IPv6 by default. Wikimedia has been using IPv6 since this date.

China The China Next Generation Internet project is a fiveyear plan initiated by the Chinese government with the purpose of gaining a significant position in the development of the Internet through the early adoption of IPv6. • China showcased CNGI's IPv6 infrastructure during the 2008 Summer Olympic Games. • The deployment of IPv6 was widespread in all related applications. • The events were streamed live over the Internet • Networked cars were able to monitor traffic conditions readily.
