从URL获取IP (C++)

#include <iostream>
#include <cstring>
#include <netdb.h>
#include <arpa/inet.h>

int main() {
    const char* url = "www.example.com"; // 替换为你要获取IP的URL地址

    struct hostent* host = gethostbyname(url);
    if (host == nullptr) {
        std::cout << "Failed to get IP address for " << url << std::endl;
        return 1;
    }

    struct in_addr** addr_list = reinterpret_cast<struct in_addr**>(host->h_addr_list);
    for (int i = 0; addr_list[i] != nullptr; ++i) {
        std::cout << "IP address " << i + 1 << ": " << inet_ntoa(*addr_list[i]) << std::endl;
    }

    return 0;
}
