Why IPV6?

The main reason for IPV6 is that IPV4 run-out of IP addresses – approx 4.3 Billion combinations ran-out. Thus, IPv4 addresses couldn’t meet the demand for Internet-connected devices. To overcome this problem we needed alternative which should be more secure, Scalable, and Connectable. IPV6 – The primary function of IPv6 is to allow for more unique TCP/IP address identifiers to be created.

It also enhanced Network with:-

  1. SECURITY
  2. SCALABILITY
  3. CONNECTIVITY
  4. More Efficient Routing
  5. Simplified Network Configuration
  6. Support For New Services
