The Transition From IPv4 To IPv6 ? Will It Be Smooth?


When we are talking about the transition from one version to another version, we have to understand the need or requirement which is the main reason of the launch of the newer version of anything. IPv4 and IPv6 are Internet Protocol Version 4 and 6 respectively. When we access the internet, we are unaware about the technologies and processes which make it possible for us to access our data and communicate with any other device using internet. The internet is nothing but a web of systems for transmission and transfer of data from one place to another though virtually. Internet protocol is the system which provides you with a specific and unique IP address. The IPv4 has the capacity to provide up to 4.3 billion IP addresses. The need of upgrading from IPv4 to IPv6 was felt when it was understood that the IPv4 is not going to be able to provide the necessary IP addresses in future.




The number that is 4.3 billion seems big, but if we consider the rate of growth and development of internet across the world, then it is evident that this number I not sufficient.

Therefore the next version that is IPv6 was introduced in 1999. As the main reason the IPv6 was conceive was need for additional IP addresses, you can see that it suffices that purpose quite adequately. Where the address size of IPv4 was 32-bit number, the address size of IPv6 is 128-bit number. You will see the difference when you will see the number of IP addresses can be provided by the IPv6. It supports 340,282,366,920,938,000,000,000,000,000,000,000,000 IP addresses as compared to 4.3 billion addresses of IPv4. The switch from IPv4 to IPv6 will take lots of money and time as there have to be changes in the infrastructure because the software and routers which support IPv4 will not be able to do that with IPv6. IPv6 is still new, so nobody knows what kind of issues or problems are going to arise in this transition, but if we want that the internet should function as smoothly in future too, then it is important that this switch is made.
