sangtech.cn 优化建议

1、当前解析结果集中在香港阿里云节点，整体响应良好，建议利用dns解析查询在线、dns测速在线功能持续监控，针对海外巴西等区域可引入dns选优策略或智能dns调度，提升全球访问体验。
2、多数查询在35-129ms之间，少数高延迟节点需关注，建议借助dns污染检测工具、dns测试网站开展dns劫持检测和dns污染查询，确保解析纯净性，同时优化dns解析速度测试频率。
3、鉴于存在部分异常解析指向海外，建议部署国内公共dns或阿里公共dns作为备用，结合dns历史解析记录查询分析记录变更，并利用dns检测工具进行dns在线检测，巩固dns服务器查询的稳定性。
