Summary

Every computer or device that accesses the Internet uses the Internet Protocol (IP) to communicate. This book discusses the latest version of IP, version 6 or IPv6. While the IPv6 specifications have existed for more than a decade, deployment has been lackluster. However, with the announcement in 2011 that the current IP version, IPv4, has nearly run out, interest in IPv6 has grown substantially. This is due to the fact that new Internet users will by necessity have to use IPv6 addresses. This will change the Internet over time from a homogeneous IPv4 network to a mixed IPv4-IPv6 Internet. To communicate ubiquitously on the Internet, organizations will need to support both protocols of the mixed IPv4-IPv6 Internet.

Author Biography

Timothy Rooney has worked with IP technologies in various capacities over the last 17 years, including systems engineering and development. He has an extensive background in IP, telecommunications, wireless services and software. Prior to joining BT Diamond IP, Tim worked at AT&T Bell Laboratories, Cingular, Triton PCS and Lucent, including a leadership role managing the VitalQIP software product to its peak as market leader. While at BT Diamond IP, Tim has managed the engineering development and market introduction of four next-generation IP management systems: NetControl, IPControl, Sapphire appliances and ImageControl. Tim has written two IPAM books and holds a Bachelor of Science in Commerce and Engineering Sciences from Drexel and a Master of Science in Electrical Engineering from Rutgers University.

Michael Dooley is responsible for overall operations of the BT Diamond IP division. Prior to joining the team, he was President and CEO of Diamond IP Technologies, a company that was acquired by INS, and in turn by BT. Before Diamond IP Technologies was formed, Michael was Vice President of Operations for the VitalSoft line of software products at Lucent Technologies, and Vice President of Engineering at Quadritek Systems. Michael has more than 20 years of experience managing and developing large scale software products. He is a graduate of Temple University in Philadelphia.
