DNS-over-QUIC（DoQ，RFC 9250）是一种通过UDP端口853在QUIC协议上运行DNS查询的隐私保护型DNS传输方式。QUIC内置TLS 1.3加密、无队头阻塞的多路复用，以及比[[dns-over-tls|DoT]]等基于TCP的方案更快的连接建立速度。DoQ在批量查询时比[[dns-over-https|DoH]]延迟更低，在网络连接频繁切换的移动场景中优势尤为突出。
示例
AdGuard DNS supports DoQ at `quic://dns.adguard.com` — compatible clients can resolve names with TLS 1.3 encryption and QUIC's 0-RTT reconnection speed.
