IPv6 (Internet Protocol version 6): The Complete Course

Explore IPv6, its 128-bit source and destination addresses, simplified headers, built-in security, no broadcast, roaming across networks, and an expanded address space to meet future device growth.

Explore the IPv6 protocol structure, detailing the 128-bit address divided into eight 16-bit blocks, hexadecimal notation with colon separators, and compression rules for leading zeros and double colons.

Explore IPv6 header extensions and prefix notation, including hop-by-hop and destination options, fragmentation, and security features, and understand network, subnet, and device addressing.

Explore the differences between IPv4 and IPv6, from 32-bit vs 128-bit addresses to header design, fragmentation, multicast handling, auto-configuration, and IPsec support.

Explore IPv6 address types, including unicast for one-to-one communication and multicast for delivering data to a group of devices, with examples like browsing, downloading, and content delivery networks.

Explore IPv6 unicast addresses, including global unicast, link-local, and unique local addresses, and learn how prefixes, subnet IDs, and interface IDs define their scope and use.

Explore IPv6 addresses, including global unicast addresses, 64-bit prefixes and interface IDs, the 6to4 addressing concept, and the format and embedding rules for IPv6 addresses.

Explore IPv6 multicast addresses and how a unique source sends to a group of devices using a multicast group ID. Understand prefix formats and scope levels from link-local to global.

Learn about IPv6 interface IDs, including manual IDs, modified EUI-64 with ff:fe insertion and U/L bit flipping, and random auto-configured IDs for addressing and security considerations.

Explore ICMPv6, the multi-purpose internet control message protocol for IPv6, handling reporting, diagnostics, and neighbor discovery through type fields and extension headers, including destination unreachable and time-exceeded messages.

Explore ICMPv6 message types, including destination unreachable and echo request/reply, and learn how packet size, time exceeded, and header fields affect IPv6 diagnostics.

Explore the IPv6 neighbor discovery protocol, including address resolution, neighbor unreachability detection, and duplicate address detection, and learn how it enables stateless auto-configuration and secure network reachability.

Explore IPv6 neighbor discovery messages, including solicitation and advertisement exchanges, and learn how destination addresses, ICMP types, flags, and DHCPv6 options govern router interactions.

Explains IPv6 neighbor discovery through neighbor solicitation and neighbor advertisement messages, detailing how devices resolve link-layer addresses and update the neighbor cache, with related options and flags.

Explore IPv6 neighbor discovery, including redirect messages, and learn how secure neighbor discovery protects neighbor discovery messages with authorization, authentication, and timestamps.

Explore IPv6 autoconfiguration, including stateful and stateless methods, link-local and global addresses, and dynamic host configuration; learn duplicate address detection, address lifetimes, and path MTU discovery.

Explore IPv6 multicast listener discovery (mld) across versions 1 and 2, including multicast group concepts, group management, and mldv2 source filtering.

Explore multicast routing concepts, including distribution trees, spanning trees, and shortest-path routing, showing how sources and receivers join or leave groups and trade-offs between memory and path optimality.

Learn how IPv6 routing uses routing tables to determine the best path, configuring static and dynamic routes, next-hop addresses, metrics, and timers across routers within autonomous systems and BGP/IGP contexts.

Explore IPv6 routing protocols, focusing on the distance-vector algorithm, its 16-hop limit, and how updates propagate; note limitations like slow convergence and routing loops.

Explore how IPv6 routing protocols exchange routing information between networks, including EIGRP as a hybrid protocol, BGP for inter-autonomous-system reachability, and IP prefix advertisements.

Explore how IPv6 quality of service differentiates traffic with integrated services and differentiated services, defining bandwidth allocation, signaling, and packet classification to support real-time data and voice over IP.

Explains DHCPv6 basics for IPv6 networks, showing how the DHCPv6 server provides address configuration, DNS information, and options via neighbour discovery protocol and IPv6 mechanisms.

Explore how the domain name system translates hostnames to IPv6 addresses using DNS servers, recursive resolvers, and caching, with DNS records and dnssec security.
