IPV4 - IPV6 Conversion
This Bloginar's goal is to chat about the motivation to transit from IPv4 to IPv6 and what are the advantages of IPv6 over IPv4. the presenter will also discuss about the concept of IPv64 and how to implement IPv6 in order to make compatible with the current IPv4 networks.
Presenter:
Jason Jia, PhD. Jason earned both his PhD in Instructional Technology from Wayne State University and his MBA degree from the University of Detroit Mercy in 2007. He has many professional certifications, including Microsoft (MCSE, MCP), CompTIA (Security+, Network+, A+). With the experiences as an IT professional in the field (i.e. helpdesk, system admin, and IT consultant) for ten years, he also lectured on networking essentials, network security, HTML, PL/SQL, and database design as a full-time/part-time faculty at University of Detroit Mercy in the past 9 years. Finally, he is currently a member of many professional associations, including Alpha IOTA Delta, International Society for Performance Improvement (ISPI), Financial Management Association (FMA), Midwest Business Administration Association (MBAA), and Golden Key International Honor Society.

Migration from IPv4 to IPv6
The groundwork for today’s Internet was the result of the Department of Defense’s Defense Advanced Research Projects Agency Network, or DARPANET. In the late 1960s there was a growing interest by universities to build a network connecting their current research infrastructures. ARPANET was first used in 1971 and made use of IP’s predecessor, the Network Control Protocol (or NCP). IPv4 became more finalized as the official RFC’s for TCP\IPv4 were documented. With IPv4 was released in 1980, the growing need for computer networking means that more and more hosts require IP addresses, which lessens the pool of available addresses. By 1989 there were approximately 100,000 hosts connected to the Internet. That figure jumped to approximately 1,000,000 by 1992. Numbers increased dramatically in 1993 with the release of GUI browsers for HTML. In 2000, half of the address space had been used and 74% of the addresses are used by North America. Since 2000, IT has moved quickly into new parts of the world such as India and China. The rest of the world has not stood still either as the number of Internet users increases every day.
For the Internet to work there is a need for each user or device to have a unique identity - and so there is a problem with IPv4. Today, home networking is not limited to connecting a few computers in a home—it expands to all devices that require IP addresses. Cellular phones, televisions, video equipment and refrigerators are among the IP capable devices that are on the market now and the growth of this market shows no signs of slowing.
The growing number of Internet hosts has quickly caused a shortage in IP addresses and will eventually consume the entire address space. The exponential growth of home networking has created a greater demand for a new Internet Protocol—IPv6. As the next-generation Internet Protocol version designated as the successor to IPv4, it is an Internet Layer protocol for packet-switched internetworks. Defined in December 1998 by the Internet Engineering Task Force (IETF), IPv6 is quickly gaining popularity in many countries in the world—especially in Asia where there is a huge demand for IP addresses by business and individuals alike.
With more and more countries intending to migration from IPv4 to IPv6, it is not surprising to hear people asking the following questions:
1) Why do we need to migrate from IPv4 to IPv6?
2) What are the advantages of IPv6 over IPv4?
3) What are the major differences between IPv4 and IPv6?
4) What are some of the major considerations while planning the migration from IPv4 to IPv6?
5) What are the major techniques/methods that facilitate transition from IPv4 to IPv6?
6) What are the basic steps necessary in the transition process?
Please share with us what you know about the migration from IPv4 to IPv6. In the meantime, we would like to know if you have any questions that we can answer.
