ubuntu12.04 lts
菜单：工具-->附加组件

点击，上面菜单，它是连接服务器：services.addons.mozilla.org （63.245.216.134 ）

问题：
1.直接在浏览器输入IP地址：63.245.216.134
显示：图
是什么原因？

2.在终端输入命令：

代码:

ubuntu@ubuntu:~$ curl http://63.245.216.134  -I
HTTP/1.1 404 Not Found
Server: nginx
Date: Tue, 09 Jun 2015 06:44:24 GMT
Content-Type: text/html; charset=utf-8
Content-Length: 162
Connection: keep-alive

是什么原因？
