Preventing DNS filtering bypass by Encrypted DNS (DoT, DoH, DoQ)
DNS over HTTPS (DoH) and other encrypted DNS protocols like DNS over TLS (DoT) & DNS over QUIC (DoQ) enhances user privacy and security by encrypting DNS queries in transit, shielding them from eavesdropping, tampering, and censorship on untrusted networks. This prevents ISPs and local attackers from logging or manipulating domain resolutions, fostering a more…
