192.30.252.122 这个地址是 github 吗？

This topic created in 3648 days ago, the information mentioned may be changed or developed.

刚刚安装 joe 的时候，在 iterm2 终端中输入

git clone [email protected]:karan/joe.git

出现

Cloning into 'joe'...
The authenticity of host 'github.com (192.30.252.122)' can't be established.
RSA key fingerprint is SHA256:xxxxxxxxxxxxxxxxxxxxxxxxx.
Are you sure you want to continue connecting (yes/no)?

然后把 192.30.252.122 这个地址输入到 chrome 中，出现：

您的连接不是私密连接

攻击者可能会试图从 192.30.252.122 窃取您的信息（例如：密码、通讯内容或信用卡信息）。 NET::ERR_CERT_COMMON_NAME_INVALID

使用 Safari 打开，也提示不安全，但是打开后，进入的是 github.com ，请问这是什么原因？这个到底安不安全？
