IPv6 Webinars Phase I

Introduction to IPv6

Main: Feb 4, 2021

Lab: Feb 11, 2021

Main: [Video] [Slides]

Lab: [Video] [Slides]

To be successful in implementing and understanding IPv6 networks, you need to first understand the IPv6 address methodology which is, in many ways, a fundamental change from the IPv4 paradigm. In this introduction, you will become familiar with what is different as well as what is the same with IPv6.

• Public and private addresses
• IPv6 Prefixes
• IPv6 Address Structure
• IPv6 Interface ID
• IPv6 Addressing and Address Allocation Methods (stateless, statefull)
• Address types, unicast, multicast, anycast
• Address categories: global, site local, link local
• Unique Local Unicast addresses
• Zero compression
• Special addresses (loopback, unspecified, IPv4 mapped IPv6)
• Broadcast address elimination


This webinar will be followed by a hands-on lab to illustrate the concepts shown.  You do not need any equipment to participate.  We will send full instructions so that if you wish, you may do the same commands / exercises but this is entirely optional.

IPv6 Address Planning

Main: Apr 8, 2021

Lab: Apr 15, 2021

QnA: Apr 29, 2021

Main: [Video] [Slides]

Lab: [Video] [Slides]

The agenda topics include:


  • Review the important prefixes needed for an IPv6 address plan,

  • Discuss how a good address plan makes security and routing policy easier,

  • Consider numbering your LAN segment, SSID, or VLAN,

  • Consider numbering for sites, backbone, links,

  • Consider how to remember your addresses for diagnostics and troubleshooting, and

  • Look at plans that other enterprises have done.

IPv6 Transition Technology

Main: May 6, 2021

Lab: May 13, 2021

Main: [Video] [Slides]

Lab: [Video] [Slides]

Enterprises rarely switch over from IPv4 to IPv6 in one step. Generally, companies will run dual-stack for a time, where both IPv4 and IPv6 are available on devices. This doesn't solve most of the problems IPv6 was designed to solve, so we will discuss the benefits and drawbacks of:

  • Dual-stack

  • NAT44

  • Dual-stack Lite

  • NAT64/DNS64

  • 464xlat

  • MAP-T

  • MAP-E

  • IPv6-Only

The agenda topics for this class include:

  • DHCPv6 Modes

  • DHCPv6 Relay

  • Address Allocation

  • Basic Commands: Client

  • Basic Commands: Server / Relay

  • Prefix 'Hints'

IPv6 and Cloud

Part-1: June 17, 2021

Part-2: June 24, 2021

Part-1: Removed 

Part-2: [Video] [Slides]

The agenda topics for this class include:

  • IPv4 address depletion status

  • Will cloud providers charge for IPv4?

  • Unique Local Addresses (ULA)

  • Can / should ULA be used in Cloud?

  • Oracle cloud IPv6 addressing lab 

  • AWS cloud IPv6 addressing lab

Introduction to IPv6 Security

Main: July 8, 2021

Main: [Video] [Slides]

This session discusses the ways enterprises might want to think about migration to IPv6.

Some vulnerabilities may be the same as IPv4 while other will be different.

Vulnerabilities may be introduced by additional complexity, for example, transition mechanisms or dual-stacking.

When many enterprises think about security, a number of areas are involved. These include:


  • Audits/Compliance

  • Threat detection

  • Risk analysis

  • Root cause determination

  • Encryption

  • Privacy

  • Confidentiality

  • Penetration testing
