IPv6 and IPv4 Security Challenge Analysis and Best- Practice Scenario

Sharing of information and resources among different devices require networking. As networks are expanding day by day, Internet Protocols are gaining more and more popularity. Different transition mechanisms have been established and yet a lot of research is to be carried out. Internet Protocol version 6 (IPv6) is the next generation Internet Protocol proposed by the Internet Engineering Task Force (IETF) to supersede the current Internet Protocol version 4 (IPv4). To enable the integration of IPv6 into current networks, several transition mechanisms have been proposed by the IETF IPng Transition Working Group. This work examines and empirically evaluates two transition mechanisms, namely 6-over-4, and IPv6 in IPv4 tunneling, as they relate to the performance of IPv6.
