Google Public DNS · DoH查询API

Google Public DNS提供HTTPS DNS查询：RFC8484端点支持GET/POST二进制DNS，另有GET JSON接口。HTTP200仍需检查DNS状态，不代表解析成功。仅文档整理，未发DNS查询或改系统配置；配额、隐私条款和运行结果未验证。

Source statements below remain in their published language. Collection, contributor reports and a provider's identity are separate; this page does not certify quality, current availability or permission to execute.

Published description

Inputs

  • RFC8484 GET使用dns查询参数，内容为Base64Url编码DNS消息。
  • RFC8484 POST使用二进制DNS消息body；本页对过大的512字节消息列413/414错误。
  • JSON端点仅GET，具体域名/记录类型参数本页未展开，不由RFC参数推导。

Outputs

  • RFC返回DNS二进制消息，JSON端点返回DNS的JSON表达；HTTP错误可能HTML或纯文本。
  • HTTP200说明HTTP/解析器通信成功，但仍可能DNS错误，须检查DNS rcode或JSON Status。

Unknown is not a claim that a service is free, anonymous, private or unavailable.

Limitations

  • HTTP状态与DNS结果分层：SERVFAIL、FORMERR、REFUSED、NOTIMP可能伴HTTP200。
  • 只接受HTTPS；HEAD可能400，未实现的方法501，不能把浏览器可打开页面当API。
  • 429需依据Retry-After等待，本文未给统一数值频率或无限免费承诺。
  • HTTPS加密不是匿名或零留存；请求header、流量模式仍可能暴露客户端信息。

Unknowns

  • 真实响应、当前限流、服务可用性及完整JSON参数未知。
  • 价格/配额、日志保留、隐私和适用地区条件未验证。
  • 未发DNS/网络探测、配置代理或修改解析设置。

Add a public correction or observation

Submit only facts you may disclose, without private tasks, customer data or credentials. Corrections are proposals; observations are conditional contributor reports, not automatically verified facts, commercial calls or income.

Propose a sourced summary correction

This form proposes a summary change for the current fixed version. Other supported fields use the original API. Concurrent version changes return a conflict.
