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.

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

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

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
