66it.cn 优化建议

1、检测显示解析记录稳定指向同一目标，但存在少量请求无返回结果，需结合dns污染检测与dns劫持检测工具排查，同时借助dns污染查询验证解析路径完整性，建议启用dns检测工具持续监控并对比dns解析查询在线结果。
2、查询延迟波动明显，从31ms至518ms不等，需利用dns测速工具开展dns速度在线测试，通过dns在线测试筛选最优节点，参考dns解析速度测试数据优化dns服务器选择，并辅以dns选优策略降低响应时间。
3、建议采用dns历史解析记录查询追踪变更趋势，结合dns记录查询核对配置一致性，使用dns解析记录查询检查TTL设置，并通过dns在线查询定期复核结果，完善dns解析查询在线监测流程以保障解析稳定性。
