IPv6 Fundamentals

Course details

Every device on the internet is assigned an IP address for identification and reachability purposes. With the rapid growth of the Internet, existing and emerging convergence scenarios in telecom and internet, the emerging Machine-to-Machine (M2M) and the internet of things-IOT; it is evident that the address space provided by IPv4 is not adequate to handle the immense IP addressing requirements. The knowledge of IPv6 addressing along with the associated transformation from IPv4 to IPv6 is highly placed on the agendas of CIOs and CTOs of organizations. This training course is designed to provide the participants with practical knowledge of IPv6 and related technologies. It covers important topics like addressing, address auto configuration, IPv6 datagram, ICMPv6 features, neighbor discovery and multicast listening discovery protocols, mobility support and security in IPv6.
