Dual Stack Mobile IPv6 is an extension of Mobile IPv6 to support mobility of devices irrespective of IPv4 and IPv6 Networks. This is implemented by combining different modules. IPv4 private networks are behind Network Address Translation (NAT) devices. So, to bypass the Binding Update and Binding Acknowledgment by NAT, the authors need to encapsulate it in User Datagram Protocol (UDP) Packets. So, the Dual Stack Mobile IPv6 should support NAT Traversal and Detection. With the support of NAT Detection and Traversal Module in Dual Stack Mobile IPv6, the mobile node is able to move freely from IPv6 Network to IPv4 Network or vice-versa.
