Cloudflare runs the largest authoritative DNS server for their customers. The best way to make the DNS server faster is to make users query it directly.
For Cloudflare-hosted domains, instead of:
User → ISP's DNS resolver → ns.cloudflare.com.
User → [ 1111 → ns.cloudflare.com. ]
184.108.40.206 runs on our existing hardware deployed around the world, it costs us very little. When you use it it improves performance for the 8 million or so sites we sit in front of, that's our actual business.
