Program code:

#include <stdio.h> #include <stdlib.h> #include <winsock2.h>//connection to the Winsock library #pragma comment (lib, "ws2_ 32.lib ") void Main () {    //Call Wsatartup Initialize Winsock library    wsadata wsadata;    :: WSAStartup (        Makeword (2,2),// Version number is 2.2        &wsadata        );    Char szhost[256];//holds the domain name or server name    printf ("Please enter the domain name that needs to be resolved:");    scanf ("%s", szhost);    Hostent *phost =:: gethostbyname (Szhost);//Get address information by hostname    ///A host may have multiple network cards, multiple IPs, and the following code outputs all IP addresses    in_addr addr;    for (int i=0;; i++)    {        //Get Address (network byte)        char *p = phost->h_addr_list[i];        if (NULL = = p)        {            break;//exit loop        }        //Copies the address to the IN_ADDR structure        memcpy (&addr. S_un. S_ADDR, p, phost->h_length);        Convert in_addr to host byte order        char *strip =:: Inet_ntoa (addr);        Print IP address        printf ("%s"%d IP addresses are:%s\n ", Szhost, I+1, StrIP);    }    System ("Pause");}
