如何从sockaddr获取IP地址

#include<stdio.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>

int main() {
    struct sockaddr_in sockaddr;
    sockaddr.sin_family = AF_INET;
    sockaddr.sin_addr.s_addr = inet_addr("192.168.1.1");

    char ip[INET_ADDRSTRLEN];
    inet_ntop(AF_INET, &sockaddr.sin_addr, ip, INET_ADDRSTRLEN);

    printf("IP address: %s\n", ip);
    return 0;
}

import socket

sockaddr = socket.inet_aton("192.168.1.1")
ip_address = socket.inet_ntoa(sockaddr)

print("IP address:", ip_address)

import java.net.InetAddress;
import java.net.UnknownHostException;

public class Main {
    public static void main(String[] args) {
        try {
            InetAddress address = InetAddress.getByName("192.168.1.1");
            String ipAddress = address.getHostAddress();
            System.out.println("IP address: " + ipAddress);
        } catch (UnknownHostException e) {
            e.printStackTrace();
        }
    }
}
