网友都知道，上海 CN2 精品网 58 开头的 IP 很香。不过，其实还有更香的。那就是上海 CN2 的 A 池 IP。
我们平时看到的 58.32 和 58.33 其实是B池（很佩服上海电信的起名艺术） IP，保障等级不及 116 开头的 A 池 IP 。今天快车道有幸拿到一台 A 池 IP 的 500M 对称 CN2 VDS ，就来测给大家看看。
MTR 测试
MTR 去 Vultr 新加坡测试IP。上A池机，下B池机（下同）。A池丢包率好 0.1% ，延迟低 1.1 ms 。

因为啊～～～
A池测试机是 500M 上下行对称线路。B池测试机是 500M 下，200M 上的非对称线路。
总结
A池比B池好一点点，现在来看差别有限。也许要等到 CN2 负载跑过 95% 的时候，他们的差别才能体现出来吧。
