测试可能不太严谨，如有疏漏及错误之处请指出
先看入口 IP ，看来入口是任播 IP ，广东移动在省内就能访问无需路由去上海这点非常满意

后端的解析服务器数量达到了阿里和百度的水平，做到了每个省三大运营商都有一个后端递归服务器这对解析准确度非常重要，还支持 ECS 这点值得表扬，最令人惊喜的是居然支持提交的 ECS 为 IPv6 且能正确返回（目前国内支持的只有阿里、dnspod 、百度三家）
内蒙古移动（提交的 ECS 为 IPv6 ）

更多地区请大家自测我懒得复制了
但大小问题还是有的就比如老生常谈的问题：dns 记录第一次解析延迟偏高还需要优化，教育网无服务器这点对教育网用户不太友好，以及返回的 CLIENT-SUBNET 掩码错误会导致以该 DNS 为上游的自建 DNS 服务器 ECS 失效

关于污染问题其实不需要测试因为只要后端在境内就不可能没有污染，海外服务器的有无及质量本人无测试条件还需其他大佬帮忙
首先要肯定的是完成度还算不错至少能满足普通人对解析准确度的要求，但还存在的问题希望能进一步优化，同时希望字节能提供公共 NTP 服务器来缓解这一在中国大陆互联网压力最大的免费公共服务
