It’s unanimous: The current Internet Protocol, IPv4, is inadequate for the surging demand for Internet connectivity across every aspect of the global economy. Primarily, it’s because the structure of IPv4 addresses limits how many can be created, but there are security, workload, architecture, and mobile-device-compatibility issues as well.
Today’s IP addresses consist of four numeric sequences separated by periods, like this: 201.65.2.57. That is a 32-bit IP address (four sequences contains 8 bits). Because of the proliferation of IP addresses through the bi-level architecture that assigns IP numbers (to a network and the hosts on that network), the 32-bit addressing schema of Internet Protocol version 4 holds the distinct possibility that those four billion addresses will soon be exhausted.

Ever wonder who establishes internet protocols? In 1991, the Internet Engineering Task Force (IETF) recognized that the Internet would outgrow IPv4. In early 1999, IETF created the IPv6 Forum to address the pending shortage of IP addresses and other limitations of IPv4.
Four years later, a new Protocol was made ready for general availability. In mid-2004, The Internet Corporation for Assigned Names and Numbers (ICANN) announced that the root DNS servers for the Internet had been modified to support both IPv6 and IPv4 (called ”dual stack”).

Even after all of the arguments for an IPv6 upgrade are spelled out, the fact of the matter is that IPv4 is being phased out. Any forward-looking enterprise must convert to IPv6 if it wants to maintain a secure, optimized connection to the Internet. It not only allows for practically limitless IP addresses, but it offers remarkable more capability in these areas:
- Addressing and Routing
- Security
- Administrative Workload
- Support for mobile devices
- Sophisticated peer-to-peer communication tools
