IPv6 Security Issues—A Systematic Review

IPv4 has been used over 30 years. It proved robust, interoperable, and easy implementation. The number of users is raising dramatically, the growth and development of IPv6 are vital. This protocol provides many new features like larger address space, auto-configuration, QoS, IPsec, easier TCP/IP administration, mobility, etc. In addition to these features, IPv6 development brings new security issues; however, many attacks were inherited from IPv4, which harm IPv6 networks. Those attacks affect both IPv4 and IPv6 networks. This paper explains and analysis the common threats in IPv4 and IPv6, security threats which introduced by new features of IPv6, and transition threats.
