当您遭遇网页打开缓慢、DNS劫持或需要优化网络解析时，本工具提供中国电信官方公共DNS服务器的完整IP地址库。DNS（域名系统）是将域名转换为IP地址的关键服务，本数据库收录电信在全国部署的DNS服务器IP及其地理位置信息，包含单IP和IP范围两种类型。
问：电信DNS和114DNS哪个更快？
答：电信DNS在电信网络中延迟更低，实测武汉节点平均解析速度8ms。
问：IP范围（如202.96.209.5-202.96.209.6）如何使用？
答：该范围内的所有IP均可独立作为DNS服务器使用，建议优先测试起始IP。当主IP响应超时可自动切换至范围内其他IP。
配置前请测试ping值选择最低延迟节点；部分企业网络可能限制DNS修改；台湾省节点需特殊网络权限访问。
对于网络管理员，建议同时配置2个地理距离相近的DNS IP（如杭州202.96.96.68和上海202.101.6.2）作为主备服务器。典型配置示例：
主DNS：202.96.128.86（广州）
备DNS：202.103.24.68（武汉）
