caixin.com DNS检测结论
- 检测时间
- 2026年9月28日 22:05
- 完成节点
- 315/315
- 获得 DNS 响应节点
- 311 (98.7%)
- 平均 DNS 查询耗时
- 42 毫秒
本次 DNS 查询测试整体 DNS 响应率为 98.7%，低于 99% 的告警阈值，315 个节点中有 4 个未返回有效结果。整体 DNS 查询时间中位数 19 毫秒，多数运营商响应稳定，海外节点延迟明显偏高。
caixin.com 各运营商 DNS 表现
DNS 响应率按取得 DNS 响应及查询耗时的节点计算，P50 表示一半响应查询的耗时不超过该值；响应不代表一定解析出地址，也不等同于 DNS 传播或污染判定。

重点发现
- 整体 DNS 响应率 98.7%，低于 99% 阈值，315 个节点中 311 个获得响应，4 个为未应答查询。
- 电信响应率 96.9%，123 个响应节点；联通与移动均为 100%，移动平均 DNS 查询时间 22 毫秒，电信 27 毫秒。
- 海外节点中位 DNS 查询时间 1 毫秒但 P90 达 182 毫秒、平均 160 毫秒，响应时间分布明显分散。
- 观测到 6 个不同的解析地址，仅反映应答多样性，不能据此判断解析正确性或根因。
改进建议
- 本次 DNS 响应率为 98.7%，低于 99% 复核线。建议先复测未响应节点；若持续失败，再核对权威 DNS 服务、查询记录类型和对应解析记录。
