For IPv4
Why we need IPv6
Now the Internet is evolving again, to
the embedded space. How big will it
become? Intel Vice President Doug
Davis cites the IDC prediction of 15
billion intelligent, connected devices by
the year 2015.¹

...that's 745,700,281,327,299,000,000,000 years!
To put that into perspective, the universe is roughly 15 billion years old
How long would it take to perform this test using a single 10 GigE port?
(15,000,000,000).
BTW, it would take around 5 minutes for IPv4.

IPv6 Rapid Deployment (6rd)
RFC-5969
6rd specifies a protocol to deploy IPv6 to sites via a service provider's IPv4 network.
It builds on 6to4 with the key differentiator that it utilizes an SP's own IPv6
address prefix rather than a well-known prefix (2002::/16)
6rd views the IPv4 network as a link layer for IPv6
