DNS over HTTPS (DoH)

DNS Over HTTPS (DoH) is an internet protocol developed by the Internet Engineering Task Force (IETF) as an upgrade to existing DNS. It is designed to improve users’ privacy and security by encrypting Domain Name System (DNS) requests and responses with the Hypertext Transfer Protocol secured (HTTPS) protocol. It is intended to provide a secure and encrypted connection when DNS requests are sent online.

DoH has two major advantages over standard DNS. The first is the increased privacy of DNS requests, as the actual request will be encrypted instead of sent in plaintext. This guarantees that ISPs and other potentially malicious actors will not be able to monitor users’ online activities.

The second is an improvement in security since the DNS query will be securely encrypted and no longer vulnerable to man-in-the-middle attacks. This helps against DNS rebinding and similar attacks, as an attacker would not be able to intercept and manipulate the request.

DoH is still fairly new and is not yet widely adopted. Its advantages have been argued over since its conception due to concerns over web censorship and other issues. Proponents argue that DoH provides improved privacy, security, and potentially faster loading speeds.

DoH is an important protocol for improving users’ security and privacy online and is becoming an increasingly popular choice for both developers and users. It provides a secure, encrypted connection when performing DNS requests and should be considered when it comes to choosing a DNS provider.
