31dou.net 优化建议

1、检测显示域名当前解析在多个香港阿里云节点间轮询,但返回结果中混有expired.hichina.com,表明域名已过期或解析异常,建议优先检查域名续费状态,确保dns解析查询在线结果稳定。
2、dns测速在线数据中,各节点query_time波动明显,从最快0ms到最慢820ms,且存在一次空结果,说明线路质量不均,建议利用dns检测工具针对杭州移动dns、西安移动dns等关键地域进行dns测速,筛选低延迟节点。
3、当前解析全部指向香港节点,对于国内用户访问可能造成dns延迟测试偏高,建议配置智能dns或增加国内节点,缩短dns解析速度测试响应时间,并定期进行dns污染检测,保障解析纯净。
