126.96.36.199 is a free Domain Name System (DNS) service by American company Cloudflare in partnership with APNIC. The service functions as a recursive name server providing domain name resolution for any host on the Internet. The service was announced on April 1, 2018. On November 11, 2018, Cloudflare announced a mobile application of their 188.8.131.52 service for Android and iOS. On September 25, 2019, Cloudflare released WARP, an upgraded version of their original 184.108.40.206 mobile application.
The 220.127.116.11 DNS service operates recursive name servers for public use at the four following IP addresses. The addresses are mapped to the nearest operational server by anycast routing. The DNS service is also available for Tor clients. Users can set up the service by manually changing their DNS resolvers to the IP addresses below. Mobile users on both Android and iPhone have the alternative of downloading the 18.104.22.168 mobile application, which automatically configures the DNS resolvers on the device.

188.8.131.52 is a recursive DNS resolver. Cloudflare runs an authoritative DNS resolver with a network of over 20 million Internet properties. With the recursor and the resolver on the same network, some DNS queries can be answered directly.[third-party source needed]
With the release of the 184.108.40.206 mobile application in November 2018, Cloudflare added the ability for users to encrypt their DNS queries over HTTPS (DoH) or TLS (DoT). Later on, a VPN tunnel based on WireGuard was implemented.
Technology websites noted that by using 220.127.116.11 as the IP address for its service, Cloudflare exposed misconfigurations in existing setups that violated Internet standards (such as RFC1918). 18.104.22.168 was not a reserved IP address, yet was abused by many existing routers (mostly those sold by Cisco Systems) and companies for hosting login pages to private networks, exit pages or other purposes, rendering the proper routing of 22.214.171.124 impossible on those systems. Additionally, 126.96.36.199 is blocked on many networks and by multiple ISPs because the simplicity of the address means that it was previously often used inappropriately for testing purposes and not legitimate use. These previous uses have led to a huge influx of garbage data to Cloudflare's servers.
The 188.8.131.52/8 IP block was assigned in 2010 to APNIC; before this time it was unassigned space. An unassigned IP space, however is not the same as a reserved IP space for private use (called a reserved IP address). For example, AT&T has said it is working on fixing this issue within its CPE hardware.
In September 2019, Cloudflare released a VPN service called WARP which is built into the 184.108.40.206 mobile app.
