Introduction To IPv6

IPv6 standards have been around for well over a decade now. However, the takeup of IPv6 has been really very low and realistically, there has been no need to implement it until now. Indeed, there has never been and actually still is no real 'killer application' that demands the use of IPv6. However, now has come the time where there is a real business case for at least exploring, if not implementing IPv6. The business case is driven by the fact that the pool of IPv4 addresses available for allocation has practically been exhausted. Wihout IPv6, IP networks cannot grow any longer.

Learning Objectives

At the end of the course, the delegates will understand:

  • The key differences between IPv6 and IPv4
  • The reasons why IPv6 is important
  • IPv6 addressing
  • The IPv6 header
  • The Auto-configuration features of IPv6
  • New aspects of ICMP - ICMPv6
  • IPv6 Neighbour Discovery
  • Strategies in migrating to IPv6
  • plus others...
Live Demonstrations

Included in the course are live demonstrations of the following:

  • End-station IPv6 configuration
  • IPv6 Auto-configuration
  • IPv6 router configuration
  • Network analysis of IPv6 packets
  • IPv6 DNS operation
Who Should Attend

This course will be beneficial to those wishing to gain a high-level understanding of IPv6. An understanding of IPv4 networking would be helpful but not necessary.
