IPv6 is a new internet protocol. In what way does IPv6 resolve the current problems and limitations of IPv4?
Understanding how IPv6 will take over the chores of IPv4
Â
IPv6 is about to take over IPv4 in the long run due to the main problem of address space in IPv4 ( only 32 bit address.).
Â
Comparison of IPv4 to IPv6
Â
1. Headers of IPv4 and IPv6 are different.
2. IPv6 has bigger address space which is 128 bits while IPv4 has only 32 bits. About 3.4×1038 addresses in total.Â
3. Can do multicasting which is the transmission of packet to many destinations (broadcast is replaced by multicast in IPv6).
4. IPv6 hosts can arrange themselves automatically when connected to a routed IPv6 network.
5. Internet Protocol Security (IPsec) was originally developed for IPv6, but can be seen as widespread deployment first in IPv4
6. Packet header size is twice but has easier mobility, a fragmentation mechanism enhanced & checksum is simplified.
7. IPv6 avoids triangular routing therefore it is more efficient.
8. The header is of fixed size (40 octets) which extends the Option availability of security, quality of service & mobility.
9. IPv6 node can handle packets as large as 4294967295 (232−1) octets while IPv4 can handle only 65535 (216−1) octets
10. Privacy extension towards static IP address is improved by an operating system that generates ephemeral IP addresses by concatenating a randomly generated host identifier with the assigned network prefix rather than the traceable static IP addresses. These extensions are default in Windows, Mac OS X (since 10.7), and iOS.

Since we all know that there is already a new version of the IPv4 Internet Protocol and it is the Internet Protocol version 6 or known also as IPv6, it is not yet completely implemented and they guess it to take many years for it to be completely implemented. This is because of the drastic change done in the version 6 that has great effect on the version 4. The creation of IPv6 was really planned as replacement for IPv4.
Although the greater part of the internet traffic of the present year 2013 still uses IPv4, the traffic share of IPv6 as of the later part of November 2012 was described to be approaching around 1%. This justifies that it is being slowly implemented as time goes by. As for the benefits of using IPv6 over IPv4, it creates a more effective routing. It decreases the size of routing tables thus making the routing more effective. It also has a more efficient packet processing. This is because IPv6 uses simplified packet header that makes the packet processing more efficient.

Each of your comments has been just great and also appropriate for a newbie. Thanks experts, for assisting me to understand a complex technology. I really appreciated your comments because they consist a lot of information especially to the newbie like me that want to resolve the issues about technology that evolve. I could not make head or tail of this technology that’s why my previous exploits inspiring me to search for more information took me to many sites, but all my efforts ended in smoke, in the case of their sites speech was a hotchpotch, explaining nothing. But now with your comments, I have come to the know that which way Ipv6 resolve the current problems and what its limitations. Well done guys.
