Hi Firoz, IPv6 (Internet Protocol version 6) is the answer to overcome the problem of exhaustion of currently used 32 bit long IPv4. Since IPv6 is 128 bits long hence it has a much larger address space than the currently used IP address system. This expansion provides flexibility in allocating addresses and routing traffic and eliminates the primary need for network address translation (NAT), which gained widespread deployment as an effort to alleviate IPv4 address exhaustion.
