QUIC was developed with HTTP in mind, and HTTP/3 was its first application. [35] [36] DNS-over-QUIC is an application of QUIC to name resolution, providing security for data transferred between resolvers similar to DNS-over-TLS. [37] The IETF is developing applications of QUIC for secure network tunnelling [36] and streaming media delivery. [38]
However, partially due to the protocol's adoption of QUIC, HTTP/3 has lower latency and loads more quickly in real-world usage when compared with previous versions: in some cases over four times as fast than with HTTP/1.1 (which, for many websites, is the only HTTP version deployed).
RFC 9250, published in 2022 by the Internet Engineering Task Force, describes DNS over QUIC. It has "privacy properties similar to DNS over TLS (DoT) [...], and latency characteristics similar to classic DNS over UDP". This method is not the same as DNS over HTTP/3. [43]
Google's QUIC data technology is now an official internet standard, potentially improving connections worldwide.
Technitium DNS Server [18] [19] is a free, opensource [20] (GPLv3), [21] cross platform, authoritative, caching and recursive DNS server software. It supports DNS-over-TLS, DNS-over-HTTPS, and DNS-over-QUIC encrypted DNS protocols. [22] It also supports DNSSEC signing and validation for RSA and ECDSA algorithms with both NSEC and NSEC3.
A public recursive name server (also called public DNS resolver) is a name server service that networked computers may use to query the Domain Name System (DNS), the decentralized Internet naming system, in place of (or in addition to) name servers operated by the local Internet service provider (ISP) to which the devices are connected.

On September 2, 2020, with the release of Chrome 85, Google extended support for Secure DNS in Chrome for Android. DNS-over-HTTPS (DoH), was designed to improve safety and privacy while browsing the web. Under the update, Chrome automatically switches to DNS-over-HTTPS (DoH), if the current DNS provider supports the feature. [139]
Support for HTTP/3 was added to Cloudflare and Google Chrome first, [16] [17] and is also enabled in Firefox. [18] HTTP/3 has lower latency for real-world web pages, if enabled on the server, and loads faster than with HTTP/2, in some cases over three times faster than HTTP/1.1 (which is still commonly only enabled).
