    • 10. Vision of JCA on IPv6 training: present situation
      • Knowledge on IPv6, if existent, is very fragmented
      • Formal class training offers the advantage of concentrated knowledge about the protocol
      • Serious IPv6 (training) efforts already being done by
        • Banks
        • Governmental organisations (EU, NATO, Belnet)
        • Vendors of connectivity devices
        • ISP’s
        • In each of those private sectors, forerunners and late adopters
      • Main customer base of Belgacom/JCA: no ‘sense of urgency’ yet
      Unrestricted Slide 27/12/10
    • 11. Evolution 27/12/10 Unrestricted Slide
    • 12. Why IPv6?
      • At beginning of course, I like to find out what customers know already of IPv6.
      • First question: “What keywords pop up in your mind when you think about IPv6?
      • I mostly get one, sometimes two answers, but that’s it.
      27/12/10 Unrestricted Slide
    • 13. Why IPv6? 27/12/10 Unrestricted Slide IPv6? Expanded Address Space Efficiënt Header Efficiënt Routing Autoconfiguration Security Mobile IP Multicasting Scoped Adresses No more NAT DHCPv6 QoS
    • 14. Training to raise awareness
      • Customers are not aware of all possible features and benefits of IPv6.
        • But, are all these features usable or improvements to IP?
      • Main known features are IPv6 address space and security.
        • And security is questionable, IPsec not implemented in all IPv6 stacks.
      • Exhaustion date for IPv4 address pool is not impressing customers.
        • When showing , there is no “ oh my god ”-feeling.
      • Despites regulation coming from governments and other authoritative organisations, IPv6 is very slowly implemented in networks.
      • IPv6 offers a few ‘cool’ new networking features.
        • But unfortunately these don’t add to the go/no go decision.
      • When going for IPv6, a lot of applications and devices are not
      • IPv6 enabled yet.
        • So IPv6 implementation will only be partial today.
      27/12/10 Unrestricted Slide
    • 15. Training to raise awareness
      • Lot of customers are not convinced about IPv6 in internal networks.
        • They mainly think IPv6 is about larger address space.
        • Internally everything runs on private space IP addresses.
        • To the outside mapping with NAT
        • NAT delivers also a (false) impression of security.
        • Why do we need to change that?
      • Most customers are convinced about IPv6 for external services.
        • Make external services available for new customers with (only) IPv6.
      27/12/10 Unrestricted Slide
    • 16. Training to raise awareness : Security!
      • Convince customers IPv6 is not only about addresses.
        • There are a few more things.
          • End-to-end transparency, more efficiënt packet structure, reducing routing tables, ...
      • We weren’t really able to convince customers on the other aspects of IPv6.
      • We tried to convince the customers on their ‘weak’ side: security.
      • Not the security implemented by IPv6. But the security risk you have by running IPv6 without knowing.
        • You have dual stack devices in your network today.
          • Windows Vista, 7, 2008, Mac OS X, Linux, ...
        • You have IPv6 running today without you knowing it runs internally.
        • IPv6 uses auto-configuration.
        • You don’t need IPv6 connectivity to get attacked based on IPv6.
        • Hackers are already exploiting this.
      27/12/10 Unrestricted Slide
    • 17. Training to raise awareness : Security!
      • The hacker is interested in IPv6
        • IPv6 network traffic isn’t monitored together with IPv4 traffic. IPv6 traffic is probably not monitored at all.
        • IPv4 security measures (perimeter firewalls, filter ACLs) are often not replicated for IPv6.
        • Law enforcement isn’t ready to deal with hacks involving IPv6 (Does the Computer Crime Unit of Belgian Federal Police have already IPv6?)
        • Understand how IPv6 works to make your network more secure!
      27/12/10 Unrestricted Slide
    • 18. Training to raise awareness: Real reasons for IPv6
      • Well recognised:
        • Exhaustion of IPv4 addresses space
          • Q1 of 2011
      • Often overlooked:
        • End-to-end transparency
          • Public IPv6 addresses, no NAT
        • Need to reduce size of routing-table.
          • Default-free routing tables: 350.000 entries, slow convergence, …
        • IPv6 has been mandated in some environments (e.g., theoretically government networks)
      27/12/10 Unrestricted
    • 19. Training to raise awareness: Bogus reasons for NOT deploying IPv6
      • Misunderstandings, still alive
        • “ IPv4 exhaustion thing is exaggerated. There will always be a solution to extend the use of IPv4 addresses.”
          • IPv4 address space runs out in Q1 of 2011. No way out.
          • NAT is not a final solution, it’s a temporary work-around.
        • “ IPv6 addresses are to difficult to understand.”
          • It’s just a matter of getting used to the address format.
        • “ Customers are not asking for IPv6 support yet.”
          • Several companies are convinced that IPv6 is needed for extension of Internet and are seeking providers supporting IPv6.
          • It is a bit the “chicken-and-egg-problem”.
            • ISP’s are not implementing IPv6 because customers
            • are not asking for it.
            • Customers are not implementing IPv6 because no
            • ISP supports it.
      27/12/10 Unrestricted
    • 20. Which types of customers?
      • ISP’s (Belgium)
        • Core-backbones are IPv6 ready.
        • But they wait until more IPv6 request from customers.
        • Should be the firsts to implement IPv6, but why invest now?
        • Providers with large blocks of IPv4 address space are waiting, planning study and testing for 2011 and implementing in 2012.
        • Providers with small blocks have more specific plans for study, testing (2010) and implementing IPv6 (2010-2011).
      • Large private enterprises with international networks
        • Banks, Automotive industry, Transport, ...
        • They see the need for IPv6 to support network expansion.
        • Starting study and testing of IPv6 beginning of 2011. Implementation towards end 2011.
      27/12/10 Unrestricted Slide
    • 21. Which types of customers?
      • Public enterprises
        • Air Traffic control, Public ISP, ...
        • They (have) implement(ed) IPv6 because of government requirements (e.g.: EC, Belnet, ...)
      • Companies developing products with network-connectivity
        • Medical imaging, Storage, ...
        • Their customers are asking for IPv6 support.
        • Planning IPv6 support in products with next releases in 2011.
      • Companies developing network-devices.
        • Broadband routers, Set top boxes, Multi-media streaming, ...
        • Their customers (ISP’s in France and Netherlands) are asking for IPv6 support.
        • Planning IPv6 support in products with next releases in 2011.

    • 22. Which types of customers? 27/12/10 Unrestricted Slide
    • 23. Testimonials
      • Marc Lampo, Security Officer, EURid
        • The IPv6 Essentials course was a real eye-opener.
        • The teacher addressed the various aspects of the new protocol and gave a clear insight in the challenges that await network and security administrators when they start deploying IPv6 in their networks.
        • I strongly recommend this course, both for its contents as well as the excellent presentation by the teacher.
      • Kurt Vanslambrouck, Manager Network Competence Center, Agfa-Gevaert
        • The IPv6 Essentials course has compared IPv6 to IPv4 in a very clear way
        • Registering IPv6 ranges is one thing, preparing our complex organisation for IPv6 is something else.
        • Internally, a lot of experimenting is being done. However, the possibilities towards the Internet are very limited, because of the slow adoption of IPv6 by the large Belgian ISP’s.
      • Average satisfaction score: 4,5/5
      27/12/10 Unrestricted Slide
    • 24. Specific IPv6 training needs
      • Some companies have specific needs about IPv6 training.
      • They ask for tailor-made courses.
      • These companies have really started implementing IPv6.
      • Companies developing network-devices.
      • Mainly because of the question of their customers.
        • Their customers are big ISP’s in France and The Netherlands and require broadband routers with IPv6 support.
      • Difficult to find (in Belgium): training about programming IPv6 sockets.
      27/12/10 Unrestricted Slide
    • 25. Vision of JCA on IPv6 training: how to prepare the market for the IPv6 future
      • Still a lot of training work remains to be done before IPv6 can become a reality
      • JCA tries to
        • Encourage people to start experimenting with IPv6 in a lab setting
        • Make people reach out to their colleagues including
          • Network engineers
          • Domain name server administrators
          • System administrators
          • Support staff
          • Security and abuse handling people
          • Your vendors
        • Convince customers deployment can be incremental.
        • Make people think about the right reasons for (non-)deploying IPv6.
      27/12/10 Unrestricted Slide
    • 26. Conclusion
      • There is no way out!
        • Predictions are that IPv4 address space will be out in January 2011 @ IANA
      • IPv6: soon coming to a network near you!
        • Scouts motto: “Be prepared!”
      • Learn and understand what IPv6 is all about.
      • A lot of companies and networks risk a fast, unprepared implementation of IPv6, when they don’t start to act now with at least the first step: training.
      • Study, test and deploy. In that order.
      27/12/10 Unrestricted Slide
    • 27. Thank you!
      • This is not the end. It is only the beginning.
