In 2016, almost every site using Cloudflare (over 4 million) had enabled IPv6, leading to significant global IPv6 traffic where networks have enabled it for consumers. Top IPv6 networks include Orange Polska, China Next Generation Internet CERNET2, and HiNet IPv6 (Taiwan). The adoption of IPv6 is driven by its faster internet capabilities compared to IPv4. Countries like Belgium, Ireland, Greece, Germany, Ecuador, Luxembourg, Portugal, Estonia, India, and Peru have shown significant growth in IPv6 connectivity. Major networks responsible for the majority of IPv6 traffic through Cloudflare include T-Mobile USA, Verizon Wireless, AT&T, Microsoft, AIS Fibre (Thailand), Google Fiber, Sky (UK), Alentus, EGIHosting, and Facebook.
