3 IPv4 IPv6 For IPv4

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. From : Matthew Jefferson(Matt)

IS IPv4 NAT a Realistic Alternative ?

The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets: (10/8 prefix) (172.16/12 prefix) ( /16 prefix) 2001:DB8:0:1::1

15 How to provide Ipv6 Using Ipv4 IPv6 Rapid Deployment 6rd

16 Case study for IPv6 Rapid Deployment

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 IPv4 IPv6 IPv6

18 6rd Example ( Customer Edge Example)
6rd Prefix/n bits CE IPv4 add 0-32 bits Subnet ID 0-16 bits 2001:DB80::/32 2001:DB80: 64 64:0100: Interface ID 64 bits IPv6 IPv6 CE IPv4 address BR IPv4 Address BR IPv4/IPv6 CE = Customer Edge BR = Border Relay RG = Residential Gateway or CPE = Customer Premises Equipment The CE IPv4 address can be configured or from DHCP The CE IPv4 address can be global or private (RFC 1918)
