Internet Protocol version 6 is a revision of the Internet Protocol (IP) developed by the Internet Engineering Task Force (IETF). IPv6 is intended to succeed IPv4, which is the dominant communications protocol for most Internet traffic as of 2012. IPv6 was developed to deal with the long-anticipated problem of IPv4 running out of addresses. IPv6 implements a new addressing system that allows for far more addresses to be assigned than with IPv4. Transition technologies were developed to support the transition from the IPv4-based Internet to IPv6-based Internet. This paper discusses the transition mechanisms that will allow both traditional IPv4-based Internet end-user sites and new IPv6- only Internet sites to utilize IPv6 and operate successfully over the existing IPv4-based Internet routing infrastructure.
