What is Cloudflare DNS?
Cloudflare DNS is a public domain name system (DNS) resolver that was launched in April 2018. It is part of Cloudflare's suite of services designed to make the internet faster, more secure, and more reliable. Cloudflare DNS stands out due to its focus on privacy and speed, promising users that it will not log their IP addresses and that it will make their web activities significantly faster.
At its core, Cloudflare DNS acts as a bridge between users and the websites they visit. When a user types a website address into their browser, the DNS resolver converts that human-readable domain name into an IP address that computers use to identify each other on the network. Cloudflare DNS aims to perform this function faster and more securely than traditional DNS providers.
Key Features of Cloudflare DNS
- Privacy Focused: Cloudflare DNS is committed to user privacy, offering features such as DNS over HTTPS (DoH) and DNS over TLS (DoT) to encrypt DNS queries.
- Speed: Designed to be one of the fastest DNS services available, Cloudflare DNS significantly reduces the time it takes to resolve domain names.
- Security: By preventing DNS spoofing and cache poisoning attacks, Cloudflare DNS enhances the security of users' internet experiences.
In addition to these features, Cloudflare DNS also benefits from Cloudflare's vast global network, which includes data centers in over 200 cities worldwide. This extensive network allows Cloudflare DNS to offer low-latency and high-speed DNS resolution to users around the globe.
How Does Cloudflare DNS Work?
To understand how Cloudflare DNS works, it's important to have a basic understanding of the DNS system itself. DNS is often compared to a phone book for the internet, translating domain names into IP addresses so that browsers can load internet resources.
The Role of DNS Resolvers
DNS resolvers, like Cloudflare DNS, play a crucial role in this process. When you enter a URL into your browser, the DNS resolver queries the DNS server to find the corresponding IP address of the domain. This process involves multiple steps:
- The user enters a URL in their browser.
- The browser sends a query to the DNS resolver.
- The DNS resolver checks its cache for the IP address of the domain.
- If the IP address is not in the cache, the resolver queries a DNS root server.
- The root server directs the resolver to a TLD (Top-Level Domain) server.
- The TLD server directs the resolver to an authoritative DNS server.
- The authoritative server provides the IP address for the domain.
- The resolver returns the IP address to the browser, which loads the website.
Cloudflare DNS optimizes this process by using its extensive network of data centers to provide faster DNS resolution. This means that even if the initial query is not in the cache, Cloudflare can quickly find the necessary information and return it to the user.

Cloudflare DNS vs. Other DNS Providers
When it comes to choosing a DNS provider, there are several options available, each with its own set of features and benefits. In this section, we'll compare Cloudflare DNS with some of the other popular DNS providers to help you make an informed decision.
Google Public DNS
Google Public DNS is one of the most widely used DNS services, known for its speed and reliability. However, unlike Cloudflare DNS, Google Public DNS logs user data for 24 to 48 hours, raising privacy concerns for some users. Additionally, Google Public DNS does not support DNS over HTTPS (DoH) or DNS over TLS (DoT), which are key privacy features offered by Cloudflare DNS.
OpenDNS
OpenDNS, owned by Cisco, is another popular DNS provider that offers a range of security and filtering features. While OpenDNS provides excellent security and reliability, it lacks the privacy-focused features that Cloudflare DNS offers, such as DoH and DoT. Additionally, Cloudflare DNS is generally faster than OpenDNS, making it a preferred choice for users prioritizing speed.
Quad9
Quad9 is a DNS service that focuses on security, blocking access to known malicious websites. While Quad9 offers strong security features, it does not provide the same level of speed and privacy as Cloudflare DNS. For users seeking a balance of speed, security, and privacy, Cloudflare DNS is often the better choice.
