Who says you can’t have fun with domain names? 🙂
The fully qualified domain one.one.one.one resolves to Cloudflare‘s free DNS service, 1.1.1.1.
It’s a playful, symmetric FQDN two subdomains deep, and it’s there to promote Cloudflare’s privacy-first DNS resolver.
Just like Google DNS (8.8.8.8) Cloudflare provides it for free. It claims to be even faster than Google’s, with the added benefit of encrypting DNS queries via the app.
While the one.one.one.one app might be a tad obsolete, the domain it sits on—one.one—was registered in 2015.
