The security risks and probable solution suggestions on a new generation internet protocol IPv6

ABSTRACTAccording to OSI reference model, transferring data between the nodes works onthe 3rd layer and is called Internet Protocol (IP). Currently the Internet Protocol is usedIPv4. This protocol has been standardized in 1981 as outlined in RFC-791. Yet fastimprovement of usage of Internet more than expected has also introduced some inherentand unexpected problems. In order to solve the above given problems, studies have beencarried out and as a result a new Internet Protocol has been emerged in 1995, the nameIPv6 was given to it and standardized. As is known, architecture of IPv4 when compared toIPv6 is insufficient and IPv6 is seen as brand new and offers broad novelties whencompared to its predecessor. Currently implementation of IPv6 occurs slowly and steadilyand yet improvements in IPv6 are not complete and still in progress.In this study, header structure of IPv6 protocol has been taken into considerationand the novelties presented by the new header structure such as applications and securityrelated problems have been discussed. First of all, information related to IPv6 were given,structure of IPv6 standard header and extension headers were investigated. The functionsrelated to header structure and their effects were investigated and some predictions werealso presented. Then, information about attacks related to Internet and some securityproblems are presented. Having gone through IPv6 technology, if expectations related tothreats mentioned above are going to still remain or changed is considered. In the last partof the studies, in relation to new protocol and header structure and the light of knowledgepresented in the previous sections, what kind of new attacks towards IPv6 may take place ispredicted? According to one of the predictions whose name is given by us to be ?ping-pong? attack has been treated separately and a solution to this problem is proposed.x
