IPv6 deployment

The deployment of IPv6, the latest version of the Internet Protocol (IP), has been in progress since the mid-2000s. IPv6 was designed as the successor protocol for IPv4 with an expanded addressing space. IPv4, which has been in use since 1982, is in the final stages of exhausting its unallocated address space, but still carries most Internet traffic.[1]

By 2011, all major operating systems in use on personal computers and server systems had production-quality IPv6 implementations. Mobile telephone networks present a large deployment field for Internet-connected devices in which voice is provisioned as a voice over IP (VoIP) service. In 2009, the US cellular operator Verizon released technical specifications for devices to operate on its 4G networks.[2] The specification mandates IPv6 operation according to the 3GPP Release 8 Specifications (March 2009), and deprecates IPv4 as an optional capability.[2]

As of August 2024, Google's statistics show IPv6 availability of its global user base at around 42–47% depending on the day of the week (greater on weekends).[3] Adoption is uneven across countries and Internet service providers. Countries including France, Germany and India now run the majority of their traffic to Google over IPv6, with other countries including the United States, Brazil and Japan at around 50%. Russia and Australia have over 30% adoption, while China has less than 10% and some countries such as Sudan and Turkmenistan have less than 1% IPv6 adoption.[4]
