1.1.1.1 is the most popular DNS application today. How to download and use 1.1.1.1 Although it is not difficult, during use, many people still have difficulty with the following things.

What is 1.1.1.1?

1.1.1.1 is a public DNS resolver operated by Cloudflare, providing a fast and private way to browse the Internet. Unlike most other DNS resolvers, 1.1.1.1 does not sell user data to advertisers. Additionally, 1.1.1.1 is rated as the fastest DNS resolving server available.

What is DNS?

The Domain Name System (DNS) is like the phone book of the Internet. While people access information online through domain names, for example example.com, computers use Internet Protocol (IP) addresses — unique strings of alphanumeric characters assigned to each property on the Internet. DNS translates domain names into IP addresses so that users can easily access a website without having to know the IP address of that website.

What is a DNS resolver?

A DNS resolver is a type of server that manages the “Convert domain names to addresses“, where the IP address is compared with the domain name and sent back to the requesting computer. DNS resolvers are also known as recursive resolvers.

The computer is configured to communicate with specific DNS resolution servers, identified by IP address. Typically, configuration is managed by the user’s Internet service provider (ISP) for home or wireless connections, and by the network administrator for office connections. Users can also manually change the DNS resolution server their computer is using.

Why should I use 1.1.1.1 instead of my Internet service provider’s (ISP) DNS resolver?

The main reason to switch to a third-party DNS resolver is to improve security and achieve faster performance.

On the security front, ISPs do not always use strong encryption on their DNS or support the DNSSEC security protocol, leaving their DNS queries vulnerable to data breaches and users to attacks in transit. Additionally, ISPs often use DNS records to track user activity and behavior.

In terms of performance, your ISP’s DNS resolution server can be slow and can become overloaded due to heavy usage. If there is enough traffic on the network, the ISP’s resolver server may stop responding to requests altogether. In some cases, attackers intentionally overload the ISP’s resolution server, leading to a denial of service (DoS).

What makes 1.1.1.1 more secure than other public DNS services?

Many DNS services support DNSSEC. While this is a good security measure, it does not protect user queries from the DNS companies themselves. Many of these companies collect data from their DNS customers for commercial use, such as selling to advertisers.

Meanwhile, 1.1.1.1 does not exploit user data. Logs are kept for 24 hours for debugging purposes, after which they are deleted.

1.1.1.1 also provides security features that many other public DNS services do not have, such as query name mitigation. This feature improves privacy by including in each query only the minimum amount of information needed for that step in the resolution process.

What makes 1.1.1.1 the fastest recursive DNS service?

The power of Cloudflare’s network gives 1.1.1.1 a natural advantage in the speed of serving DNS queries. Because it is integrated into Cloudflare’s network, which spans 330 cities globally, users anywhere in the world receive quick responses from 1.1.1.1.

Additionally, the data centers in this network have access to millions of Internet properties on the Cloudflare platform, making querying those domains extremely fast.

What is Cloudflare WARP?

WARP is an optional application built on the 1.1.1.1 platform. WARP creates a secure connection between your personal devices and the services you access on the Internet. While 1.1.1.1 only secures DNS queries, WARP secures all traffic coming from your device.

WARP does this by routing your traffic through the Cloudflare network instead of the public Internet. Cloudflare automatically encrypts all traffic and can often increase speeds by routing through Cloudflare’s low-latency paths. In this way, WARP provides some of the security benefits of a virtual private network (VPN) service, without the performance and data security issues that many commercial VPNs offer.

How to use 1.1.1.1 and WARP?

1.1.1.1 completely free. Setting it up on a desktop takes just a few minutes and requires no special techniques or software. Users simply need to open their computer’s Internet settings and replace the IP address of the current DNS service with the address 1.1.1.1.
