Cloudflare is a Global Network Service provider. They have their own DNS service that directly competes with Google’s OpenDNS Service. This Cloudflare service focuses on the privacy and security of users and their Internet connections. Cloudflare claims its 1.1.1.1 service does not keep your connection logs for more than 24 hours, which it says helps boost users’ privacy on the Internet.

Another plus point of using this DNS server is that it is faster than others. It takes 14ms for sites outside their network to be fetched and located. And it is even faster for those that are indexed by them.
Cloudflare’s service supports DNS over HTTPS (and DNS over TLS), which also protects your browsing information from your ISP. And the best part is, this service is 100% free for anyone. Also, Cloudflare claims it never uses the data for marketing or other purposes. This is demonstrated by KPMG auditing their code. For those who don’t know, KPMG is a well-respected marketing firm. They will be checking their code and practices annually, and a public report will soon be published when it is ready.
This service is now live and can be used by anyone now.
