What is IPv6
IPv6 – Internet Protocol version 6 Exists many years Gaining increased public knowledge

The History of Internet Protocol
Packet switching developed in the 50’s & 60’s First versions of IP introduced in the 70’s for
US Department of Defense programs• Highly survivable communications system
Production use in the 80’s on US DARPANET and then the Internet
90s saw the explosion of IP use on the Internet Easier more economical than other networks

The History of Internet Protocol
Too few addresses initially selected Didn’t realize how big Internet would get Arbitrarily selected 232
• About 4.3 Billion addresses
Internet initially an experiment

The History of Internet Protocol
Nobody imagined what the Internet would become• Did not envision the number and types of devices that
would connect to the Internet
2014 – 50 Billion individual elements on the Internet

Connecting to Internet
Today often have 10s of thousands of people using one IP address
With fewer IP addresses, this will become harder, resulting in • Potential for breakages – won’t be able to connect• More layered devices to allow more to connect, at a
cost of lower quality for services
Won’t see a collapse of Internet access, but will affect value added services

What is IPv6
First issue was to deal with addressing Went from 232 to 2128
4.3 Billion(4.3×109)
IPv4 Addresses
340 Undecillion(3.4×1038)
IPv6 Addresses
4,300,000,000 340,000,000,000,000,000,000,000,000,000,000,000,000

What is IPv6
Security another major issue to deal with IPsec was retrofitted to IPv4, but built in to
IPv6 from the start
On the technical side… Introduced fixed headers to enable new
capabilities not possible with IPv4 Extension Headers to enable a new stream of
innovations

Impacts of IPv6
Ability to develop networks that provide less gatekeepers in the way
IPv6 global addressing enables you to…• Minimize devices • Minimize delay• Simplify development
Headers allow development of new quality and streaming services

IPv6 Myths & Concerns
![Page 32: Slides from Introduction to IPv6](https://reader033.vdocuments.mx/reader033/viewer/2022061111/54556251af7959b8038b88e2/html5/thumbnails/32.jpg)
www.commtouch.com
Myths & Concerns
Concern – it’s new• Less experience deploying• New code to develop• Don’t have same time to understand and work out bugs
Concern – Training and understanding• There are differences – lack of IPv6 expertise
Concern – Idea of using globally routed addresses• Uncomfortable for some security professionals
![Page 33: Slides from Introduction to IPv6](https://reader033.vdocuments.mx/reader033/viewer/2022061111/54556251af7959b8038b88e2/html5/thumbnails/33.jpg)
www.commtouch.com
Myths & Concerns
Most networks already have IPv6• Need to be aware of this

IPv6 Deployment
Deployed since late 90s early 2000s Large deployment last 4-5 years Most major carriers offer IPv6 Most operating systems, many applications
support IPv6 A number of service and content providers
offer IPv6 services• Examples: Google, Netflix, Facebook
![Page 36: Slides from Introduction to IPv6](https://reader033.vdocuments.mx/reader033/viewer/2022061111/54556251af7959b8038b88e2/html5/thumbnails/36.jpg)

Impact on Service Providers
![Page 37: Slides from Introduction to IPv6](https://reader033.vdocuments.mx/reader033/viewer/2022061111/54556251af7959b8038b88e2/html5/thumbnails/37.jpg)
www.commtouch.com
Impact on Service Providers
Need to be looking at IPv6 if you’re not yet Demand from IPv6 will come from government
agencies and organizations Eventually demand from businesses and
consumer users If you’re a service provider need to look at
• How to fit IPv6 into your infrastructure• Strategically, what new services will IPv6 enable you to
offer
![Page 38: Slides from Introduction to IPv6](https://reader033.vdocuments.mx/reader033/viewer/2022061111/54556251af7959b8038b88e2/html5/thumbnails/38.jpg)
www.commtouch.com
Impact on Service Providers
IPv6 offers a product and market opportunity Will impact on a product, strategic and
business development basis• Types of services to offer • Types of customers to seek out to take advantage of
new opportunities
Your infrastructure needs to support end-user demand • Video streaming, voice, and other new capabilities

www.commtouch.com
Opportunities for Security Vendors
Tremendous room for growth Will help governments, businesses, service
providers to implement policies Some of the pieces will be the same as IPv4,
such as firewalls Some of the ways we do security will change,
such as spam filtering Greater move to host-based security
![Page 41: Slides from Introduction to IPv6](https://reader033.vdocuments.mx/reader033/viewer/2022061111/54556251af7959b8038b88e2/html5/thumbnails/41.jpg)

Transitioning to IPv6
You need an IPv6 transition plan• Map out what you have today, what you need to do and
how you need to do it
Short term: • Get interoperable with IPv6 very quickly, even if you
don’t support new features
Long term: • Plan for how you’re going to do things in the future• Simplify, cut costs and improve performance

Final Thoughts
If you haven’t started implementing IPv6, then its critical that you start
Implement something to gain experience and understand IPv6
Make sure all equipment you buy today is IPv6 enabled• Does it have capabilities that you need
Plan Try Buy Correctly
