4 ¹ "Gantz, John. "The Embedded Internet: Methodology and Findings." IDC. January 2009." 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 Why we need IPv6
5 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. How long would it take to perform this test using a single 10 GigE port? BTW, it would take around 5 minutes for IPv4. 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). 15

16 Case study for IPv6 Rapid Deployment Founded in 1999 One of the Worlds largest IPv6 residential providers Provides VoIP, IPTV, Internet, Mobile Four Million Customers (10/2010) 27% of Market Nov 7, rd presented Nov 9, 2007 Prefix from RIPE Nov 9, 2007 Beta Code on Freebox running Dec 11, 2007 Service available to 2M customers 250K users signed up in first month. 500K users enabled today (~4M ready for IPv6) IPv6 Deployment Timeline
17 IPv6 Rapid Deployment (6rd) RFC rd 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 IPv4 IPv6
