cfb.cn 优化建议

1、针对当前节点全部解析至内蒙古阿里云单一IP，建议结合dns解析在线与dns在线查询工具，深度核查dns解析记录查询结果的稳定性，同时利用dns测速在线功能对比不同地区响应差异，为dns选优提供数据支撑。
2、鉴于query_time波动范围较广，建议通过dns速度在线测试与dns解析速度检测，重点优化dns服务器查询配置，并参考dns污染查询及dns劫持检测结果，确保dns解析查询在线过程无异常干扰，提升dns测试网站的综合性能。
3、建议采用dns检测工具对dns历史解析记录查询进行持久化分析，结合dns污染检测工具验证当前解析路径的纯净度，并部署dns测速工具实现多区域dns解析在线监控，以增强dns测试网站对dns域名污染查询的响应能力。
