Certified Network Engineer for IPv6 - CNE6 Silver

This defines IP, IPv4, IPv6, etc. It also covers Global IP Address Resource Management, Issues with IPv4 Addressing, a Comparison of IPv4 and IPv6 and the Evolution of the Global Internets

This covers issues related to how IPv4 addresses were allocated globally, and how IPv6 addresses are being allocated today. It covers IANA and the Regional Internet Registries (RIRs).

This covers some of the problems associated with IPv4 addressing, including NAT and RFC 1918 addresses for private internets.

This provides a comparison of the features of IPv4 and IPv6.

This covers the history and evolution of the global Internets, from the first generation (ARPANet), through the second generation (IPv4) to the third generation (IPv6).

This shows connecting to several sample websites, including how to see what IP address the browser connected to (using IPvFoo). It also shows how to find your IPv4 and IPv6 node addresses (whatismyipaddress.com, ipv6-test.com).

This covers the various transmission modes: unicast, multicast, anycast and broadcast.

This covers the various address types for IPv4 and IPv6.

This section covers the SixConf GUI IPv6 Configuration utility I created for Windows. This is available for free download from the IPv6 Forum. Tens of thousands of users have downloaded this over the years. It is primarily useful as a pedagogical tool to help people understand IPv6, although it can be useful when deploying IPv6.

This covers how the total address spaces for IPv4 and IPv6 are organized.

This covers the concept of IP address scopes - how some IP addresses are limited in terms of what parts of the network they are defined in (interface local, link local, site local, global).

This section covers the IP address lifecycle for IPv6 addresses. All IPv6 addresses have two lifetimes, preferred and valid. Some addresses (link local, manually assigned, etc) have infinite lifetimes (never expire) by default. DHCPv6 assigned addresses use the DHCPv6 lease time as valid lifetime, and some percentage of that as preferred lifetime. SLAAC addresses by default have finite lifetimes, based on the subnet default values communicated through RA messages.

This section covers IP Address External Representation - the way IP addresses are represented for humans to read or input. In IPv4, this is "dotted decimal". In IPv6, this is "coloned hex".

This section includes how to do network configuration in Windows for IPv4 and IPv6, using the simple property dialogs included in Windows.

This section covers how IP address autoconfiguration works in IPv4 (DHCPv4) and in IPv6 (DHCPv6 and/or SLAAC).

This lesson covers multicast addresses for both IPv4 and IPv6.

Node Identity refers to what addresses a node will accept traffic to. It is very simple in IPv4, but somewhat more complex for IPv6.

This short lesson covers the special IP addresses that do not fall into one of the above Address Types. There is only one special address for IPv4, but two for IPv6.

This covers the IP packet headers for IPv4 and IPv6, including the new Packet Header Extensions for IPv6.

This is a brief introduction to ICMP, the Internet Control Message Protocol. There is a version for IPv4 (ICMPv4) and one for IPv6 (ICMPv6).

This lesson covers ICMPv4, the version of ICMP for IPv4, specified in RFC 792 from 1981. It is mostly included here for comparison with the basic ICMPv6 messages.

This section covers ICMPv6, which is the new version of ICMP for IPv6, specified in RFC 4443. It also covers the basic messages (not including the new ND or MLDv2 messages). These correspond roughly to the only messages in ICMPv4.

This brief section is an introduction to Neighbor Discovery, which is implemented by some additional ICMPv6 messages. This is where a lot of the power and automation in IPv6 lives. These mostly happen using link local addresses (including link local multicast), in the local subnet.

This lesson covers the new Neighbor Discovery Mechanisms, like Router Discovery, Duplicate Address Detection, Neighbor Unreachability Detection, and SLAAC. These mechanisms are actually implemented using the ND messages covered the next section.

This lesson covers the actual Neighbor Discovery Messages, which are used to implement the Neighbor Discovery Mechanisms, covered in the previous lesson.
