EXECUTIVE SUMMARY
IPv4 is the dominant addressing protocol used on the Internet and most private networks today. With the current exponential growth in Internet users worldwide, combined with the limited address range of IPv4, the number of available public IPv4 addresses remaining is very limited. IPv6 is the next-generation Internet protocol that will replace IPv4, providing a vastly expanded address space. This white paper provides an update on the current industry status of IPv6, how the IPv4 to IPv6 transition will affect some organisations, and Telstra’s perspective on the transition.
Internet Transition
IPv4, the dominant addressing protocol, is rapidly running out of capacity and will be replaced by IPv6
The protocol that governs communication on the Internet (and most intranets) today is called Internet Protocol version
