Did you know? DNS used to overshare by tradition, not necessity. QNAME minimisation lets a resolver ask the root about .com without handing it the full hostname you looked up. RFC 9156 explains that intermediate name servers only need enough of the name to point to the next delegation. Your resolver still sees the full query; this reduces what it tells the rest of the DNS hierarchy. #privacy #dns #cypherpunk
