例如下面一个非常奇怪的现象，通过 python get 内网地址 遇到 No route to host
但是 curl 可以成功。
requests.exceptions.ConnectionError: HTTPConnectionPool(host='10.0.0.200', port=8000): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x1061976f0>: Failed to establish a new connection: [Errno 65] No route to host'))

python 代码非常简单
requests.get("http://10.0.0.200:8000")
可能是什么原因呢？
