IPv6 Training Course - Hands On Internet Protocol - Version 6

Overview

Learn IPv6 with our IETF member expert instructors. The next generation of the IP protocol is a revolutionary change in the core layer of all modern LAN/WAN infrastructure.  IPv6 implementations are underway at carrier and enterprise networks.  Your team needs to be prepared for this critical and surprisingly complex evoluition.  In this class we build on attendees IPv4 skills and prepare for IPv6 migration.  Topics such as IPv6 addressing, tunnelling, and NAT considerations are all explored in this hands on, lab based seminar.

What you will learn

Learn how IPv6 operates.  Understand the design intent behing many of the changes and improvements over IPv4.  Learn why is it preferrable to use ICMPv6 instead of ARP for layer 2 address integration.  Understand the role IPsec plays in IPv6 deployments.  Really think about NAT and why it interferes with Peer-to-Peer applications such as SIP, explore how to secure a non-NAT IPv6 network.  Examine IANA IPv6 number assignments and allocations of address space to ARIN, RIPE, etc.

Who Needs to Attend

Anyone involved in managing, building, or deploying IP based networks need to start preparing for IPv6 migration will benefit from our IPv6 Training class.  This training course is suitable for IT staff, software developers and others with a knowledge of existing IPv4 operations.

Prerequisites

A background with TCP/IP is essential.  Attendees should complete TrainingCity's TCP/IP class before attending or have equivalent experience/knowledge.  If you are not sure, call us and speak with one of the instructors anytime.
