IPv6 Tutorials and Primers


Introduction: IPv6 Basics

  • What is IPv6?
    IP version 6, IPv6, is the new Internet Protocol for the world's growing multitude of mobiles, tablets, sensors, computers and routers.
  • Why Use IPv6?
    What are the differences between IPv4 and IPv6? Why is IPv6 better than IPv4? Here is a comparison of IPv4 and IPv4 in six important areas.
  • An Internet Protocol Primer
    Nearly all possible IPv4 addresses have now been allocated, and unlike telephone numbers, when you run out of network addresses you can't just add another digit: a new protocol, IPv6, is required.

IPv4 vs IPv6: The Benefits

  • Reasons for IPv6: Carrots and Sticks
    The Internet, the Cloud, or the Internet of Things can't grow without IPv6. It builds larger, cheaper, easier networks. See our list of IPv6 carrots and sticks.
  • IPv6 Capabilities
    IPv6 offers enhanced and new capabilities: vastly increased address space, fixed 40-byte headers, autoconfiguration, IPsec support, end-to-end transparency, extension headers, anycasting, mobileIPv6, and flow label QoS.
  • IPv6 Myths
    IPv6 is not just a way to avoid the address space crunch, it is also a path to innovation and new opportunities. But some tenacious myths about IPv6 can cause unwarranted concern.
  • IPv6 Advantages
    The number of connections in the Internet creates a valuable network effect. Because IPv6 will greatly increase the number of connected devices, the network effect will also greatly increase.
