About Course

Understanding and Mastering IPv6 is a complete, practical course designed to help you understand IPv6 from the ground up.

The course begins with the history and design philosophy of IPv6, then moves into IPv6 addressing, subnetting, packet structure, Neighbor Discovery, SLAAC, DHCPv6, routing, migration strategies, network design, and security. Along the way, you will learn not only how IPv6 works, but also how to configure, verify, secure, and troubleshoot it in real network environments.

This course is ideal for network engineers, students, certification candidates, IT professionals, and anyone who wants to move beyond basic IPv6 theory and develop a clear, practical understanding of the protocol.

Through clear explanations, diagrams, packet analysis, and hands-on lab examples, you will learn how IPv6 operates and how it differs from IPv4 in real deployments.

By the end of the course, you will be able to understand IPv6 addressing, configure IPv6 on network devices, explain Neighbor Discovery and SLAAC, work with DHCPv6, implement IPv6 routing, understand migration strategies, design IPv6 networks, apply first-hop security features, and troubleshoot IPv6 problems with confidence.

IPv6 Packet Operation
This unit explains how IPv6 packets operate as they move through a network. You will learn the structure of the IPv6 packet header, how extension headers add flexibility, and how fragmentation works differently from IPv4. The unit also covers Path MTU Discovery, IPv6 multicast, and anycast communication. By the end of this unit, you will understand how IPv6 packets are built, processed, forwarded, and delivered using the mechanisms that make IPv6 efficient, scalable, and reliable.

IPv6 Address Configuration
This unit explains how IPv6 addresses are configured and used on real devices. You will learn how on-link communication works, why link-local addresses are essential, and how ICMPv6 and Neighbor Discovery support IPv6 operation. The unit also covers Interface ID generation, SLAAC, DHCPv6, and manual IPv6 configuration. By the end of this unit, you will understand how IPv6 hosts obtain addresses, discover routers, communicate on the local link, and choose the correct configuration method for different network environments.

IPv6 Routing and Migration
This unit explains how IPv6 is routed, deployed, and designed in real networks. You will learn the fundamentals of IPv6 routing, including routing tables, static routes, link-local next hops, and dynamic routing protocols such as OSPFv3 and MP-BGP. The unit also covers IPv6 migration strategies, including dual stack, tunneling, and translation, as well as key IPv6 network design principles such as hierarchy, summarization, standard prefix sizes, and scalable address planning. By the end of this unit, you will understand how IPv6 networks are routed, how they coexist with IPv4 during migration, and how to design IPv6 addressing plans for real-world deployments.

Securing and Troubleshooting IPv6 Networks
This unit focuses on securing and troubleshooting IPv6 networks in real-world environments. You will learn how to protect the IPv6 first hop using features such as RA Guard, DHCPv6 Guard, Source Guard, ND Inspection, and device tracking. The unit also explains how to filter and control IPv6 traffic with ACLs while preserving essential ICMPv6 functions. Finally, you will learn a structured approach to IPv6 troubleshooting, including interface checks, address verification, Neighbor Discovery analysis, routing validation, connectivity testing, and packet captures. By the end of this unit, you will understand how to secure IPv6 networks and diagnose common IPv6 problems with confidence.

IPv6 Wrap up and Final Exam
This final section brings the course to a close with a brief IPv6 wrap-up and suggestions for next steps. You will review how to continue practicing, labbing, and applying IPv6 in real networks. The section also includes the final exam, where you can test your understanding of the full course.
