EDNS Padding
An EDNS option that adds padding bytes to DNS messages so packet sizes reveal less information about the queried name or response. It is especially useful with encrypted DNS transports.
ODoH
Oblivious DNS over HTTPS separates the client's network identity from its DNS query by using a proxy and an encrypted message for a target resolver. The proxy sees the client but not plaintext query content, while the target sees the query but not the original client address.
QNAME minimization
A recursive-resolver technique that sends only the minimum name needed at each delegation step instead of exposing the full original query name to every upstream server. It improves privacy and can reduce unnecessary data disclosure.
