pmdcn.cn 优化建议

1、建议关注dns延迟测试与dns解析查询表现，利用dns测速在线工具周期性评估104.21.49.125和172.67.162.254两个dns记录查询节点响应差异，优先采用dns在线查询快速节点以优化dns解析查询在线体验。
2、针对dns速度在线测试结果，建议结合dns解析查询与dns速度测试分析查询时间波动，通过dns测试网站筛选低延迟节点，同时利用dns解析记录查询监控dns劫持检测与dns污染检测状态，确保dns解析记录查询在线稳定。
3、基于dns检测结果，建议使用dns检测工具和dns测试工具持续跟踪dns解析查询在线延迟，部署dns测速和dns在线测试策略，参考dns查询网数据调整dns解析记录查询配置，降低dns延迟测试波动并规避dns污染检测风险。
