Answer to Question #317342 in Computer Networks for Avi

Question

Elaborate in detail the transition strategies from the IPv4 to the IPv6 with the help of a suitable example

Answer 1

These transition strategies are Dual Stack Routers, Tunneling, and NAT Protocol Translation.  

 

1. Dual-Stack Routers: In dual-stack router, A router’s interface is attached with IPv4 and IPv6 addresses configured are used in order to transition from IPv4 to IPv6.  

The dual stack router (DSR) gives the path for all the hosts to communicate with the server without changing their IP addresses. 

 

1. Tunneling: Tunneling is used as a medium to communicate the transit network with the different IP versions.

The IPv4 networks can communicate with the transit or intermediate network on IPv6 with the help of the Tunnel. It’s also possible that the IPv6 network can also communicate with IPv4 networks with the help of a Tunnel. 

 

1. NAT Protocol Translation: With the help of the NAT Protocol Translation technique, the IPv4 and IPv6 networks can also communicate with each other which do not understand the address of different IP version. Generally, an IP version doesn’t understand the address of different IP version, for the solution of this problem we use NAT-PT device which removes the header of first (sender) IP version address and add the second (receiver) IP version address so that the Receiver IP version address understand that the request is sent by the same IP version, and its vice-versa is also possible.
