ANNOTATION

Diminishing the address space of Internet Protocol version 4 (IPv4) was the reason for the establishment Internet Protocol version 6 (IPv6). Several RFC documents that define IPv6 have been released in 1996. Despite the diminishing IPv4 address space, IPv4 is still the main Internet Protocol in 2012 due to its progressive modifications. But with the growing popularity of services that require direct communications (IP telephony, video conferencing, etc.) and the intended development of WiMAX (Worldwide Interoperability for Microwave Access) such as 4G mobile network, which provides IPv6 mobility, IPv6 could be more extended. Currently, IPv6 is implemented primarily at the core network of most Internet Service Providers.

OBJECTIVES

The main goal of the module is to introduce a student with the fundamental of IPv6. The first part of the module describes the datagram, notation and structure of IPv6 addresses. The second part deals with ICMPv6 protocol that is used to send error messages and informations, without which IPv6 cannot function properly. It also deals with the protocols that IPv6 uses for its activities. They are Neighbors Discovery protocol, IPv6 Address Auto-configuration, Domain Name System and Mobility.

KEYWORDS

IPv6, ICMPv6, datagram, addresses, Neighbors Discovery, Auto-configuration, DNS, mobility.
