As most of internet is transitioned to IPv6 the network engineers may require to deploy dual-stack enabled switches on edges earlier.Though it is quite difficult for private networks to transition from IPv4 networks that easy but the growth and evolution of the over the Internet would urge organizations to move towards this transition. If it is than why not right now? IPv6 has its advantages that are making it better than IPv4. But still without the knowledge of technology and proper study it will be a quite difficult task.Things that are causing adoption of IPv6 so long is that it is not commonly not compatible with IPv4 networks. To make this transition possible number of transition technologies with tunneling facility are used to provide cross network compatibility. Two of those facilitating technologies are 6to4 and Teredo. While both of these technologies works in different ways, the simple idea is behind is that they encapsulate packets of IPv6 network inside the packets of IPv4 network. Beside the flow of the traffic the endpoints of the tunnel are required to extract and encapsulate the IPv6
