学校的网络，应该启用了一些限制
上网很快，基本没什么封锁
但是用 ping 命令去 ping 任何主机\网站都是类似如下结果
Pinging google.com [209.85.132.104] with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.
Ping statistics for 209.85.132.104:
Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),
别人的电脑也是这样，浏览器访问都没有任何问题，请问这可能是什么原因？
