Why IPV6?
As we all know that the number of IP devices is increasing exponentially day by day due to continuous enhancement in technologies.Hence today we don't have free IP addresses(IPV4)anymore to be assigned by IANA.Infact we were already having the shortage of IPV4 addresses, but due to the NATing the problem wasn't prominent.
However, now the situation is such that NATing can't sustain and adapt the currently demanding technologies further like VOIP, Video Conferencing,IPsec etc.
Hence there is a need of IPV6, which overcomes many problems due to IPV4.
With the emerge of IPV6, we can have 2^128 addresses which is pretty large number against 2^32 addresses with IPV4.However, there are loads of technological challenges and implementation issues.Hope it will get eased with time.

Actually, in the initial phase i am trying to give the basic view in simple language sothat ppl needn't struggle much to have basic idea on technology.
