In this IPv6 introduction, we will look at what I will cover, and what the objectives of the course are. If you are new to IPv6 - consider this a great starting point. This is a technical class, not a marketing class. There are no configuration labs in the class per se. You certainly can follow along with items you can look at on your computer. We have extensive hands on lab exercises in our premium community. That said, you will see configuration examples and demonstrations in the class.
Observe the IPv6 neighbor discovery process in a hands-on lab, bringing interfaces up, triggering neighbor solicitations and advertisements, and inspecting the neighbor cache as hosts ping reachability.
Discover how IPv6 stateless auto configuration uses router solicitation and router advertisements to learn prefixes, with flags, lifetimes, and optional DHCPv6 guidance, enabling devices to auto configure addresses.
Learn IPv6 address renumbering via router advertisements, with overlapping lifetimes to adopt new prefixes. Grasp path MTU discovery, 1280-byte MTU, and how too-big packets trigger ICMPv6 errors and cache updates.
Explore IPv6 routing fundamentals, including internal and external gateway protocols, OSPF version 3, and multi protocol BGP, plus enabling IPv6 on routers and interfaces with instance IDs and link-local addressing.
Explore IPv6 tunneling techniques, including 6in4 tunnels, manual and semi-automatic setups, and the 2002 prefix approach, highlighting scalability, overhead, fragmentation, and security considerations.
ISATAP explains automatic tunneling for IPv6 over IPv4 by embedding the IPv4 address in the IPv6 interface ID, enabling a tunnel endpoint and ICMPv6-based neighbor discovery.
Demonstrates ipv6 over ipv4 using isatap tunneling, configuring an isatap router and client, enabling unique cast routing, and testing neighbor discovery with router advertisements.
Explore the challenges of translation between IPv4 and IPv6, explaining why static translation breaks end-to-end models, affects ports and security, and outlining basic static configuration versus dynamic options.
Explore IPv6 motivations, key differences from IPv4, 128-bit addresses, and the role of ICMP in address learning, router discovery, and multicast.
This course provides a practical introduction to IPv6 and delivers the foundational knowledge needed to understand the next generation of Internet Protocol networking. As the supply of public IPv4 addresses has been exhausted, IPv6 has become the long-term solution designed to support the continued growth of the Internet, cloud computing, mobile devices, broadband services, and the rapidly expanding number of connected systems around the world.
Understanding IPv6 is now an essential skill for network technicians, engineers, IT professionals, and anyone working with modern packet networks. However, IPv6 is not simply a larger version of IPv4. While both protocols serve the same fundamental purpose of delivering packets across networks, IPv6 introduces an entirely different approach to addressing, packet structure, configuration, neighbor discovery, routing behavior, and overall network operations.
This course serves as an overview and introductory foundation designed to help students understand what makes IPv6 different, why it was developed, and how it operates within modern networks. Topics include IPv6 addressing concepts, address types, packet structure, subnetting fundamentals, automatic addressing mechanisms, and the operational differences between IPv4 and IPv6 environments.
The material is presented in a clear and understandable format intended for both beginners and technology professionals seeking to strengthen their networking knowledge. Whether you are preparing for more advanced IPv6 studies, working toward certifications, supporting enterprise or broadband networks, or simply trying to better understand the future of Internet communications, this course provides a solid starting point for learning and understanding IPv6.
