prna.cn 优化建议

1、优先处理空响应节点，建议利用dns测速在线工具对dns在线查询结果进行复测，结合dns查询网与dns检测工具确认超时原因，排查本地dns查询至103.21.141.130的连通性，避免影响dns解析速度测试的准确性。
2、响应集中在上海电信单一节点，建议通过dns测速工具对比杭州移动dns、贵州联通dns等多地公共dns的解析结果，验证dns记录查询是否存在地域性差异，并利用dns污染检测工具确认该IP是否存在劫持风险，优化dns解析查询在线的稳定性。
3、响应时间波动明显（0-247ms），建议启用dns解析在线监控功能，部署智能dns策略分散流量，参考常用dns与国内免费dns的响应标准，结合dns选优机制降低峰值延迟，提升dns查询网站的整体用户体验。
