1.1.1.1 is a public DNS resolver operated by Cloudflare that offers a fast and private way to browse the Internet. Unlike most DNS resolvers, 1.1.1.1 does not sell user data to advertisers. In addition, 1.1.1.1 has been measured to be the fastest DNS resolver available.
Why use 1.1.1.1 instead of an ISP’s resolver?
The main reasons to switch to a third-party DNS resolver are to improve security and gain faster performance.On the security side, ISPs do not always use strong encryption on their DNS or support the DNSSEC security protocol, making their DNS queries vulnerable to data breaches and exposing users to threats like on-path attacks. In addition, ISPs often use DNS records to track their users’ activity and behavior.
On the performance side, ISP’s DNS resolvers can be slow, and may become overloaded by heavy usage. If there is enough traffic on the network, an ISP’s resolver could stop answering requests altogether. In some cases, attackers deliberately overload an ISP’s recursors, resulting in a denial-of-service.
What makes 1.1.1.1 more secure than other public DNS services?
A variety of DNS services support DNSSEC. While this is a good security practice, it does not protect users’ queries from the DNS companies themselves. Many of these companies collect data from their DNS customers to use for commercial purposes, such as selling to advertisers.By contrast, 1.1.1.1 does not mine user data. Logs are kept for 24 hours for debugging purposes, then they are purged.
1.1.1.1 also offers security features not available from many other public DNS services, such as query name minimization. Query name minimization improves privacy by only including in each query the minimum number of information required for that step in the resolution process.
What makes 1.1.1.1 the fastest recursive DNS service?
The power of the Cloudflare network gives 1.1.1.1 a natural advantage in terms of delivering speedy DNS queries. Since it is integrated into Cloudflare’s network, which spans 250 global cities, users anywhere in the world get a quick response from 1.1.1.1.In addition, data centers in the network have access to the millions of Internet properties on the Cloudflare platform, making queries for those domains lightning-fast. Overall, the independent DNS monitor DNSPerf ranks 1.1.1.1 the fastest DNS service in the world:
