在酒店、咖啡馆或酒吧等公共场所使用Wi-Fi会把你的数据暴露在不安全的网络中。
Using Wi-Fi in a public place such as a hotel, cafe or bar can expose your data to a network which is not secure.

Next time, when we want to use our laptops or our smartphones in public places which offer free WiFi networks, please think it twice or take safe measures before using them.
如果它有自己的 IP 地址，那么我们就可以在网络上使用接入点本身了；这样做的安全性要差一些，但在用于演示方面会更有趣。
If it has its own IP address, we can use the access point itself over the network; this is less secure, but more fun to use for a demo.
