Why can’t I turn off IPv6?
At Cloudflare we believe in being good to the Internet and good to our customers. By moving on from the legacy world of IPv4-only to the modern-day world where IPv4 and IPv6 are treated equally, we believe we are doing exactly that. In the Cloudflare dashboard, IPv6 is no longer something you can toggle on and off, it’s always just on. However, if you need to turn off IPv6 (and say goodbye to the modern internet), you may still do so using the Cloudflare API.
