At the CEDEC 2015 conference in Japan, the volunteer network operations team provided a Wi-Fi network that was IPv6-only by default, without explicitly announcing it, in order to test apps and raise awareness of upcoming IPv6 requirements. Over 1,700 devices connected to the network, with 65% being Apple devices. While many devices worked with the IPv6-only network, some like Android phones could not connect due to lack of support for required IPv6 features. The unconventional network drew attention from game developers and raised awareness of supporting next-generation networks, with some starting to test their apps as a result. Traffic analysis found around 25% was IPv6, showing potential savings if mobile carriers deployed IPv6 networks.
