DNS over HTTPS (DoH) for web browsers provides online security by encrypting DNS queries, traditionally transmitted in plaintext. This encryption shields queries from interception and manipulation, mitigating risks associated with unauthorized surveillance or malicious activities. With DoH, each query is encapsulated within a secure tunnel, ensuring confidentiality and integrity as users navigate the internet. This technical advancement enhances the security posture of web browsers, safeguarding sensitive online interactions from potential threats.
