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.
DNS over TLS (DoT) is a network security protocol for encrypting and wrapping Domain Name System (DNS) queries and answers via the Transport Layer Security (TLS) protocol. The goal of the method is to increase user privacy and security by preventing eavesdropping and manipulation of DNS data via man-in-the-middle attacks .

The revision DTLS 1.2 based on TLS 1.2 was published in January 2012. [33] TLS 1.3 (2018) specified in RFC 8446 includes major optimizations and security improvements. QUIC (2021) specified in RFC 9000 and DTLS 1.3 (2022) specified in RFC 9147 builds on TLS 1.3. The publishing of TLS 1.3 and DTLS 1.3 obsoleted TLS 1.2 and DTLS 1.2.

The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...
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. Reasons ...
