Getting the ip address of web sites?

Hi,

Say i've got a web site address, how do i find out its ip address?

thnx

try gethostbyname()

Code:

---

WSADATA  wsa;
struct hostent  *g_hostent;
struct in_addr MyAddr;
char IPnumber[100][100];

WSAStartup(MAKEWORD(2,2),&wsa);

g_hostent=gethostbyname("www.cprogramming.com");
for (i = 0; g_hostent->h_addr_list[i] != 0; ++i)
                { //get all IPs
                SendDlgItemMessage(parglist->hwnd,parglist->idc,WM_SETTEXT,0,(LPARAM)GETIP);
                memcpy(&MyAddr,g_hostent->h_addr_list[0],sizeof(in_addr)); //You cannot edit the hostent struct
                strcpy(IPnumber[i],inet_ntoa(MyAddr));//make into IP
                memset(&MyAddr,0,sizeof(in_addr)); //clean again before next iteration
                }
WSACleanup( ); //free winsock resources

Do not forget to include the wsock32.lib library

I copy pasted this out of a program of mine, it is possible I fergot something (hope not)


thx Fordy ;)

Or if you are talking generally, non programming then simply use ping in dos.

Do this:

c:\> ping yahoo.com


Then in the first line of the reply you will get somthing like this:

Pinging yahoo.com [216.115.109.7] with 32 bytes of data:

The IP :)

TNT

Yeah....and if you want it to run it as a single program;

Code:

---

/////////////////////////////
// Include the WS2_32.lib
//
//
#include <iostream>
using std::cout;
using std::cin;
using std::endl;
#include <string>
using std::string;
#include <winsock2.h>

int main(int argc, char *argv[])
{
    WSAData wsaData;
        struct hostent *ptrHE;
        struct in_addr add;
        string strHost;

    if (WSAStartup(MAKEWORD(1, 1), &wsaData) != 0) {
        cout << "Error";
                return 1;
    }

        cout << "Enter the host name to query" << endl;
       
        cin >> strHost;

        ptrHE = gethostbyname(strHost.c_str());
    if (ptrHE == NULL) {
        cout << endl << "Could not find the host." << endl;
        return 1;
    }

    for(int i = 0; ptrHE->h_addr_list[i] != 0; ++i) {       
        memcpy(&add, ptrHE->h_addr_list[i], sizeof(struct in_addr));
        cout << endl << "IP Number " << i+1;
                cout << ": " << inet_ntoa(add) << endl;
    }

    WSACleanup();

    return 0;
}
