Today, IPv6 comes as standard in all major operating systems. Users with IPv6 and IPv4 connectivity find that over 75% if their network traffic is carried by IPv6 rather than IPv4. Globally, the Internet is moving towards an IPv6 world.

The growth in IPv6 deployment has significant consequences for network security and in particular network forensics. Erion’s new course, IPv6 Forensics course, is designed to address the needs of those tasked with carrying out forensic investigations in IPv6 networks. This advanced course covers how to effectively collect and analyse IPv6 evidence. It covers a wide range of techniques and tools that allow an investigator to securely record the often transitory network evidence and then filter, dissect and analyse it.

Throughout the course delegates will learn how to use tools to capture packets and network information and then interpret the results. Each modules includes extensive practical work on real-life scenarios.

Modules in the four day course include:

  • IPv6 Forensics Fundamentals
  • Sources of IPv6 Evidence
  • Interpreting IPv6 Addresses
  • IPv6 Traffic Capture and Analysis
  • IPv6 Flow Capture and Analysis
  • Evidence from Neighbor Discovery (ND)
  • DHCPv6 Forensics
  • IPv6 Name Resolution Forensics
  • IPv6 Transition Forensics
  • IPv6 Application Forensics
  • IPv6 IPsec Forensics
  • IPv6 Network Evidence

Full details of the IPv6 Forensics course can be found here.

The first public course will run in February 2018. Please contact us if you require an on-site closed course or an earlier event.

In May 2017, you have the opportunity to attend advanced IPv6 training from the world’s leading IPv6 training company.

The comprehensive Implementing and Securing IPv6  course provides you with all that you need in order to plan for, design, deploy and secure IPv6 in your network.

One of our most popular IPv6 training courses.

This is an advanced technical course that is ideal for all technologists interested in learning how to both deploy and secure IPv6. It provides all that you need to understand the issues surrounding IPv6 deployment and security and includes comprehensive practical hands-on labs to allow you to gain experience with real-world scenarios.

IPv6 training is becoming increasingly relevant in 2017 with the exponential growth in the deployment of IPv6 and the increasing deterioration of the legacy IPv4 Internet.

Deploying IPv6 not only future proofs your network but it also brings with it the opportunity for performance, functionality and operational improvements. For example, Facebook found that end users using IPv6 experience a 15% performance improvement over end users using IPv4. Also, in the long term, IPv6 is the only protocol suitable as a basis for the Internet of Things (IoT).

Furthermore, we already reaching the point where organisations are not only considering moving to IPv6-only networks but have already deployed such networks. Microsoft, Facebook, LinkedIn and Cisco are amongst those who have or are in the process of deploying IPv6-only networks.

IPv6 is very different from IPv4.

The common belief that IPv6 is IPv4 with longer addresses is wrong. IPv6 is made up of many new features and functions which are often widely and subtly different from those in IPv4. Even IPv6 addresses are significantly different from IPv4 addresses, not just in size, but in how they are structured, their types, their attributes, how many their are and how they are used. It is crucially important when deploying and securing IPv6 to move away from legacy IPv4 thinking and fully appreciate the differences from IPv4.

As the world’s leading IPv6 training company, we are pleased to announced that we will be running some of our most popular IPv6 courses in Edinburgh, UK during 2017.

These include our comprehensive 5-day Implementing and Securing IPv6 course which covers all that you need to deploy and secure IPv6 in your networks.

Erion has over 19 years experience in IPv6. Over that time we have provided IPv6 consultancy and IPv6 training to leading organisations, enterprises and governments world-wide. Throughout the many IPv6 deployments and implementations that we have carried out we have consistently noticed two things; people underestimate the need for IPv6 training and IPv6 training is crucial to success.

Many assume that IPv6 is simply IPv4 with longer addresses. This is naive. Whilst the purpose and basic function of IPv6 is the same as IPv4; that is to route datagrams from a one node to another node (possibly on a different network), the features, functions, attributes and management of IPv6 are very different. Crucially, in many cases what is considered best practice in IPv4 is the opposite in IPv6. This means that staff with extensive experience of IPv4 have to have a change of mindset in order to successfully deploy IPv6.

For this reason, we have created the world’s largest portfolio of IPv6 training courses, covering all aspects if IPv6, across many different platforms and for a wide range of audiences. Continuously updated to reflect the latest standards and best practice our courses are ideally suited to ensure that you are ready to deploy IPv6 in an efficient and safe. Thereby maximising the benefit to your business.

Full details of our upcoming IPv6 training schedule can be found here. Alternatively, we can run on-site IPv6 courses for you at your premises when we can tailor the training programme to meet your exact requirements.

May 2017 Schedule

We have just scheduled courses in May 2017 for Edinburgh, UK. This includes our Implementing and Securing IPv6 course on a range of different platforms including Linux, Cisco IOS and Windows.

Full details can be found at our IPv6 training site.

Please contact us for further details.


If you are preparing to deploy and secure your network for IPv6 then this IPv6 training is for you. Erion brings you the best in IPv6 training. We have extensive experience with IPv6 having provided IPv6 training and consultancy services for over 18 years, longer than any other independent IPv6 training provider. Also, we are proud to have the world’s largest and most IPv6 training portfolio covering all aspects of IPv6 on all major platforms.

The course that you can attend in November, is one of our most popular IPv6 training courses. The course, Implementing and Securing IPv6, is a comprehensive technical course that is ideal for all technologists interested in learning how to both deploy and secure IPv6. It provides all that you need to understand the issues surrounding IPv6 deployment and security and includes comprehensive practical hands-on labs to allow you to gain experience with real-world scenarios.

This training is becoming increasingly relevant in 2016 with the announcements by all of the UK’s major ISPs that they will be turning on IPv6 for their customers this year. Now that over 50% of the world’s major content providers are IPv6 enabled and almost 100% of Internet transit providers are IPv6 enabled, end-users with both IPv6 and IPv4 find that over 70% of their traffic is over IPv6 rather than IPv4.

Deploying IPv6 not only future proofs your network but it also brings with it the opportunity for performance, functionality and operational improvements. For example, Facebook found that end users using IPv6 experience a 15% performance improvement over end users using IPv4. Also, in the long term, IPv6 is the only protocol suitable as a basis for the Internet of Things (IoT).

Despite the imminent depletion of the IPv4 address pool and the serious consequences for the IPv4 Internet, there are still many organisations that continue to delay the implementation of IPv6. Whilst the need for IPv4 in some organisations is arguably less than in others, one area that cannot be ignored is the essential need to secure current IPv4 networks against attacks perpetrated through the use of IPv6 and IPv6 transition technologies.

It is undeniable that the vast majority of current TCP/IP networks already include not only IPv6 capability, but also have IPv6 traffic flowing over them. All modern operating systems include IPv6 dual stacks (which also provide backwards compatibility for IPv4). These operating systems, including Windows, Unix and Linux all use IPv6 by default when they can. As a result, current IPv4 networks must be secured against attacks via IPv6 and associated technologies even though they may not have explicitly deployed IPv6.

Whilst, IPv6 in and of itself is to a large extent neither more or less secure than IPv4, it’s existence in a network immediately increases the “attack surface” and therefore the security risks. Since the increased risk is not simply the sum of the two protocols but a complex interaction of IPv4, IPv6, transition mechanisms and other protocols, it is fair to say that the attack surface is somewhat more than doubled by IPv6. Furthermore, IPv6 includes many new features that make it significantly different from IPv4. This not only further increases the “attack surface” but it also means that many new mitigation and security techniques must be learned.

For those who might consider the “increased risk” a reason not to deploy IPv6; remember that IPv6 already exists whether you deploy it or not. Therefore you need to secure against IPv6 threats in your IPv4 networks.

It is essential that network security managers and others responsible for network and system security learn about IPv6 now and implement appropriate security measures as soon as they can. Erion provides the world’s most comprehensive range of IPv6 training. This includes in-depth IPv6 security training, for example, our 3-day Securing IPv6 course.
