jb304.cn 优化建议

1、dns在线查询与dns测试工具显示节点解析稳定统一，仅两处超时未返回记录，建议结合dns解析查询在线工具优先排查超时节点的网络链路，并利用dns测速及dns解析速度测试评估ipv6 dns兼容性，确保dns劫持检测与dns污染查询结果均处于健康状态。
2、从dns历史解析记录查询可见全部解析指向同一上海电信IP，建议启用dns轮询或智能dns策略分散dns解析查询请求，并借助dns检测工具及dns污染检测工具持续监控dns服务器查询响应，同时优化dns地址以降低平均dns解析记录查询时间，提升dns速度在线测试表现。
3、dns域名查询响应时间跨度显著，存在低速节点，建议通过dns测速在线与dns在线测试工具对比杭州移动dns、上海dns等本地解析性能，结合dns选优机制调整dns记录查询路由，并利用dns污染在线检测与dns域名污染检测确认安全状态，保障dns查询网整体可用性。
