Quali dati espone una query
What information a DNS query exposes
An ordinary DNS query can reveal the name being requested to the local network, the recursive resolver, and—during recursion—the relevant authoritative servers. The resolver also sees the client’s address. Encryption between a device and its resolver can hide that part of the path from local observers, but it moves trust to the chosen resolver rather than removing it.
Authoritative servers may still learn which portions of a name were queried. Query minimisation can reduce that exposure. IP addresses, timing, and traffic patterns may remain observable even when DNS messages are encrypted. DNS privacy is therefore about reducing who can see which information, not making every lookup anonymous.
For each design, ask who operates the resolver, which links are encrypted, and what metadata each participant can still observe.

Choose the best answer. This quiz runs locally and sends no DNS queries to real domains.
Does encrypting client-to-resolver DNS hide the query from that resolver?
