IPv6
The internet engineering task force begin the effort to develop a successor protocols to IPv4 in the early 1990 is an internet layer protocols for packet switched internet works. IPv4 was the late version which was having some limitations that why need to develop another version name IPv6. IPv6 provides much larger address space than IPv4. It has also provided flexibility in allotting addresses and routing traffics. The adders format is extended form 32 bits to 128 bits to avoid address exhaustion and also simplifies aspects of address assignment and renumber according to the changes in internet connectivity.
