4. 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
¹ "Gantz, John. "The Embedded Internet: Methodology and Findings." IDC. January 2009."

5. Maximum packet rate for 10GigE = 14,470,000
Total addresses (2^128) = 340,282,366,920,938,000,000,000,000,000,000,000,000
Maximum packet rate for 10GigE = 14,470,000
Number of seconds required = 23,516,404,071,937,700,000,000,000,000,000
...that's 745,700,281,327,299,000,000,000 years!
To put that into perspective, the universe is roughly 15 billion years old (15,000,000,000).
A customer just asked me to help him construct a configuration that would send a single ping request to every IPv6 address in the entire IPv6 address space using a 10 Gig interface. 15
How long would it take to perform this test using a single 10 GigE port?
BTW, it would take around 5 minutes for IPv4.

A DS-Lite CPE is an IPv6 aware CPE with a B4 interface implemented in the WAN interface.
The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets:

17. 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
