墙内首发：这个新的GHS IP就是ew-in-f121.google.com（74.125.77.121）。
我们知道一般GHS IP都有形如{i}{j}-in-f121.google.com主机名，其中i和j都是任一英文字母，有人还提出过写一个shell程序去循环ping之，就可以得出可以使用的地址了，不过没看见过程序。
现在已知的{i}{j}组合有：bw、bx、cg、eh、hs、ik、qw、tw、vw、yw，那么建立一个稍微复杂一点的Google搜索“-in-f121.google.com” -bw -bx -cg -eh -hs -ik -qw -tw -vw -yw，你看到什么了，对，就是上面这个地址！
发现在大陆ghs一般都是解析到64.233.179.121，做了一番功课，搜索到目前可见的ghs ip地址(来源1、2，Google未公布的就不知道了，如果有补充的请告诉我或者在评论里回帖，谢谢)，在封#锁的时候也好换个地址。
64.233.179.121 resolves to hs-in-f121.google.com 66.249.81.121 resolves to bx-in-f121.google.com 72.14.207.121 resolves to eh-in-f121.google.com
其中64.和72.已经试验成功，66.249.等待域名解析中，不过估计问题不大。希望将来GFW不要全部封#锁，也不希望GFW看见这篇文章。

以上216开头四ip来自 AdSense for domains 设置指南，没查到主机名

PS：
1、你也可以直接指向ghs.behindgfw.com，已经将这个域名指向到可访问ip上，并保持经常更新。
2、文后标注有 (X)记号的IP好像已经被Google从GHS序列中删除了。
