如果没有的话我就换掉了，现在这个只能由cf pages申请google的证书，其他证书都下不来

2

长链接生成器？反正我没用

3

这是个域名吧

4

他这是二级域名站啊

5

感觉没啥用呀，太长了

6

长链接生成器
oo.63个o.online

7

我觉得没人会去打（

8

搞个邮箱玩？:ac01:

分配个类似o@ooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo.online的？

不过用户名也得是o，系统自动分配o的数量？

9

除了你这个和super的找不出了

10

我感觉是没啥用的，谁没事数打了多少个o啊。

其实放到SAN里就行了，CN的长度限制是63个字符，但是SAN能253个字符
