The introduction of the DNS HTTPS record type marks a pivotal shift in web privacy by enabling Encrypted Client Hello (ECH), a mechanism that finally addresses the long-standing vulnerability of Server Name Indication (SNI) leaks. By hosting public keys directly in DNS, ECH allows browsers to encrypt the intended hostname, making it nearly impossible for eavesdroppers to distinguish between different sites hosted on the same shared IP or content delivery network. While this technology is currently led by early adopters like Cloudflare and Caddy, its potential to bypass traditional censorship creates a strategic dilemma for governments, which may be forced to choose between allowing free access or "overblocking" entire service providers. Ultimately, this transition moves the web toward a privacy model resembling a sealed envelope, where specific destinations remain hidden unless an authority is willing to shut down the entire digital post office.
