IPv4 and IPv6 are the two main versions of Internet Protocol. IPv4 is the original and most widely used version, but it is limited to 4 billion addresses which may not be enough for future needs. IPv6 was developed in 1999 and provides a much larger address space to meet future demand. There are various transition strategies for moving from IPv4 to IPv6, including dual stacking, tunneling, and translation methods to allow devices and networks using the different protocols to communicate with each other during the changeover process.

1. IPV 4 AND IPV6 Group members: Tehmina Gulfam (09-arid-829) Sadaf Sabir (09-arid-814)

2. What is internet protocol? Internet Protocol is a set of technical rules that defines how computer communicate with each others. There are two currently version : IP version 4(ipv4) and IP version 6 (ipv6).

3. What is ipv4? IPv4 is the first version of Internet Protocol to be widely use and accounts for most of today’s internet traffic. There are just 4 billions IPv4 address. While that is lot of IP address, it is not enough to last forever.

4. What is ipv6? IPv6 is a newer numbering system that provides a much larger number address pool than ipv4,amongs others features. It was develop in 1999 and should meet the world’s IP address needs well into the Future.

5. Difference between ipv6 & ipv4

6. Transition strategies/Migration Mechanism Three transition techniques Dual stack Tunneling Translation Translation procedure: Allow ipv6 only devices to communicate with ipv4 only devices

7. Dual stack procedure : To allow ipv4 & ipv6 to co-exist in the same devices & networks

8. Tunneling procedure: Allows separate IPv6 networks to communicate via an IPv4 network.

9. Convert IPv4 into IPv6 Method 1:HEXADECIMAL METHOD There are two method to convert ipv4 into ipv6. 192.168.25.234 First we divide each octet by 16 and write down the remainder, 192 ÷ 16 = 12 remainder 0 168 ÷ 16 = 10 remainder 8 25 ÷ 16 = 1 remainder 9 234 ÷ 16 = 14 remainder 10

10. Convert IPv4 into IPv6 As we know that the IP address of Ipv4 was 192.168.25.234 Now the conversion of this address in Ipv6 is C0A8:19EA

11. Cont….. Method 2: BINARY METHOD Another easier way is to convert the octets into Binary. The conversion of this192.168.25.234 IP in binary system is 192:11000000 168:10101000 25:00011001 243:11101010
