DNSük

DNSük is a concept for a privacy-focused extension of the Domain Name System (DNS). It envisions a naming and query framework in which client devices use built-in DNSük resolvers and a network of privacy-preserving relays to obtain domain information without exposing sensitive metadata to intermediate observers. The design emphasizes end-to-end confidentiality, integrity, and localized caching, while remaining interoperable with traditional DNS infrastructure.

The architecture centers on three components: client resolvers, a distributed set of relays, and authoritative name servers for zones. Clients issue queries to their DNSük resolver, which forwards requests through opaque, encrypted channels (using protocols such as DNS-over-TLS or DNS-over-QUIC) and applies query privacy techniques to reduce linkage between queries and users. Relays help decouple client identity from the destination domain, and authorities provide zone data with cryptographic proofs, ideally compatible with DNSSEC or equivalent integrity mechanisms.

DNSük also supports programmable policy for data retention and selective disclosure, enabling operators to balance privacy with auditability. It is designed to be deployed alongside standard DNS, offering backward compatibility through dual-stack operation and careful handling of caching and TTL semantics.

Status sections: DNSük remains a proposal and implementation experiments rather than a standard. It has been explored in research and open-source projects as part of broader efforts to enhance DNS privacy and resilience. Challenges include performance overhead, deployment complexity, potential fragmentation of namespaces, and governance of relay trust.
