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.

IPv4 Exhaustion: Are
You Worried Yet? You've probably seen IPv4 depletion
counters ticking ominously away towards zero address hour, but what are they
based upon, and why do they matter?
