TCP/IP is the protocol used for communication on the internet. IPV4 is the version of the protocol that is currently in use. You may be surprised to learn that this protocol has been in service from a time before the internet. In computer tech terms, that is a very long time.
The time has finally come for this protocol to be laid to rest finally and for another better version to take over. IPV6 will completely take over from IPV4 soon, due to certain limitations that have started to emerge in the latter over the past few years.
Primarily, address space limitations will be solved by the introduction of the new standard. This will provide over a billion x billion addresses for each square meter of Earth, which makes it formidable indeed. It also has improved security features such as authenticity of the origin of data, end-to end data encryption, improved measures against IP spoofing and eavesdropping, etc. The new protocol will also make mobile networking better as well as improving real-time communication.
However, move from IPV4 to IPV6 will take some time. Businesses have to see the “need” before they make the switch, as they have invested heavily in the existing technology. The cost of moving to this new protocol, the cost of training, and the lack of a killer app to motivate users are the basic barriers. But nevertheless, the benefits offered by IPV6 will eventually outweigh the issues. Therefore, we will see IPV6 implementations slowly gathering momentum in the very near future.
