Transition from IPv4 to IPv6 By Anita Kanuganti Hemanth Rao Raparthi

Need for transition IPv4 -> 32 bit Address space This is being used up… Successor to IPv4 -> IPv6 IPv6 ->128 bit Address space

Transition Components Hosts Routers and the Routing Protocols Domain Name system [DNS]

Transition Techniques We can have three different types of nodes IPv4 only node IPv6/IPv4 node IPv6 node only Simplified Addressing mapping

Transition Techniques (contd.)

Dual IP layer AB C D E F IPv6 IPv4 IPv6 IPv4

Transition Techniques (contd.) Tunneling Physical view ABC DE IPv6 IPv4 IPv6

Transition Techniques (contd.) Logical View AB E C,D combine to form IPv4 tunnel

Transition techniques (contd.) IP header translation Extremely difficult Idea Abandoned by IETF, Where do I stand when compared to them……(my batch mate has good chances….)

Thank you Questions!
