itec-ces.com 优化建议

1、建议优化dns解析记录查询与dns历史解析记录查询的响应稳定性，当前dns测速在线显示部分查询耗时达721ms，需通过dns测速工具筛选最优节点并配置智能dns调度，以缩短dns解析查询在线平均时间。
2、针对dns污染检测与dns劫持检测结果，建议启用dns污染查询工具对上海电信、江苏连云港移动等区域的dns域名污染查询进行监控，利用dns污染在线检测网站验证解析一致性，并部署加密dns增强dns在线查询安全性。
3、建议结合dns解析查询与dns在线测试数据，对dns速度在线测试差异明显的dns服务器实施dns选优策略，优先采用阿里公共dns或百度dns，同时优化dns解析速度测试后的缓存策略，提升dns测速的dns查询工具与dns检测工具整体体验。
