如何使用静态 ip java 连接套接字

Question

I want to know if I can Connect Java sockets using a static IP Address. I've recently bought static IP from my ISP and I want to connect a Client Program that use Java socket with my laptop (as a server). I've tried it before in a closed network and it work normally, but when I've tried it with distributed network it doesn't work. Here is a piece of my code

---

Server :

ServerSocket serverSocket = new ServerSocket(5432);    
Socket client = serverSocket.accept();

Client :

Socket socket = new Socket(IP,5432);

The problem is what should the IP be ? The Static IP or the IPV4 ?

Answer 1

假设您购买的静态 IP 是可公开路由的（即不是 10.xxx、172.16.xx-172.31.xx 或 192.168.xx）并且您的路由器/防火墙允许从公共 Internet 访问此 IP，您应该能够访问来自任何地方的 IP。
