Modern Protocols

All DNS protocols are supported, and can be deployed to any operating system, even legacy ones that don't support them.


Control D embraces state-of-the-art technology by supporting all modern DNS protocols, placing a clear focus on secure, encrypted DNS options. This approach ensures the integrity and privacy of DNS queries in an era where cyber threats are increasingly sophisticated.

Problem Solved

Modern Protocols in DNS, especially encrypted ones, solve the issue of unsecured traditional DNS traffic that can be susceptible to interception and manipulation. By implementing these protocols, Control D protects its users from potential attacks such as eavesdropping and DNS hijacking.

Supported DNS Protocols

Control D supports dual stack (IPv4/IPv6) legacy DNS protocols, but we strongly encourage the use of their modern and encrypted counterparts. These include:

  • DNS-over-HTTPS (DoH): Encapsulates DNS in HTTPS traffic, providing encryption and authentication via the HTTP protocol. HTTP/1 and HTTP/2 are supported.
  • DNS-over-TLS (DoT): Operates similarly to DoH, securing the DNS by utilizing the TLS protocol, much like secure web traffic.
  • DNS-over-QUIC (DoQ): A novel protocol that combines the security of DoT or DoH with the performance improvements of QUIC.
  • DNS-over-HTTPS/3 (DoH3): Implements the latest advancements by integrating HTTP/3 into DoH, offering enhanced performance and security.

Benefits of Secure DNS Protocols

  • Privacy Assurance: Encrypted DNS protocols protect DNS queries from being monitored or modified by third parties.
  • Security Enhancement: Using modern DNS protocols reduces the risk of cyber attacks related to DNS such as spoofing or pharming.
  • Future-Proof Infrastructure: By supporting cutting-edge protocols, Control D prepares users for next-generation internet standards.

Using Modern Protocols with Control D

Most modern operating systems, and all browsers support DNS-over-HTTPS or DNS-over-TLS, and can be natively deployed. For software based deployments, Command Line Daemon is available which runs on every operating system and utilizes Secure DNS protocols by default. Intuitive tutorials make deployment a breeze.
