Connection speed gain is claimed to be achieved by converting TCP traffic to UDP (both IPv4 and IPv6 are supported), DNS resolution inside Cloudflare's network, and direct access to sites which are using Cloudflare's infrastructure.2019-09-25 The Technical Challenges of Building Cloudflare WARP http://blog.cloudflare.com/warp-technical-challenges/ 2023-03-22 The Cloudflare Blog en WARP connects the user through an encrypted tunnel to the closest Cloudflare data center, thereby hiding any traffic from intermediaries such as local network operators or Internet Service Providers. If the user is trying to reach a site or service outside the Cloudflare network, WARP will replace the user's IP address with a Cloudflare address that represents the user's approximate location, thus hiding the user's identity from the site or service. Previously, if a user tried to reach a destination managed by Cloudflare, the destination was provided with the user's true IP address in an X_FORWARDED_FOR header.2023-11-09 FAQ · Cloudflare WARP client docs https://developers.cloudflare.com/warp-client/known-issues-and-faq/ 2024-06-29 Cloudflare Docs en2022-04-19 WARP BUG ?

WARP+ and WARP+ Unlimited WARP+ routes users' Internet traffic into less congested pathways using Cloudflare's own private backbone, called Argo, which makes it much faster than basic WARP. WARP+ historically was a limited data plan. To get more data to use WARP+, users had to refer more people to use the service. The WARP+ Referral program is no longer available and has been discontinued.Different plans of WARP, 1.1.1.1 and WARP+ https://support.cloudflarewarp.com/hc/en-us/articles/360025731113-What-is-the-difference-between-1-1-1-1-WARP-and-WARP-Unlimited As of November 2025, WARP+ (aka WARP+ Unlimited) is a paid monthly subscription with no data limits.What is the difference between WARP, WARP+, and WARP+ Unlimited? https://support.cloudflarewarp.com/hc/en-us/articles/360025731113 WARP Client Help Center https://web.archive.org/web/20251128124854/https://support.cloudflarewarp.com/hc/en-us/articles/360025731113-What-is-the-difference-between-1-1-1-1-WARP-and-WARP-Unlimited 2025-11-28 live 19 November 2022 See also 8.8.8.8, a similar public DNS service by Google DNS over HTTPS DNS over TLS Public recursive name server IPv4 and IPv6 Quad9 References 30em External links https://one.one.one.one The Cloudflare Blog Cloudflare Docs: Setting up 1.1.1.1 Cloudflare Docs: 1.1.1.1 Public DNS Resolver Category:Alternative Internet DNS services Category:Internet properties established in 2018 Category:IP addresses Category:Cloudflare
