get IP address

[exodus300]

I think i saw something about this a while ago, but I never saw a response.

How can you get the IP address of the computer?

#include <iostream.h>
#include <winsock.h>

struct hostent *phe;
//----------------------------------------------------------
String GetLocalIP(int ipnum)
{
WSAData wsaData;
if (WSAStartup(MAKEWORD(1, 1), &wsaData) != 0)
{
return &quot;255&quot;;
}

//int retval = doit(argc, argv);


char ac[80];

if (gethostname(ac, sizeof(ac)) == SOCKET_ERROR)
{
//return WSAGetLastError();
}

//return ac;

/* attempts to find host */

phe = gethostbyname(ac);

if (phe == 0)
{
return &quot;error&quot;;
}

/* Return specified local IP address */
for (int i = 0; phe->h_addr_list != 0; ++i)
{
struct in_addr addr;
memcpy(&addr, phe->h_addr_list, sizeof(struct in_addr));
//cout << &quot;Address &quot; << i << &quot;: &quot; << inet_ntoa(addr) << endl;

/* returns specified IP */
if (i == ipnum)
return inet_ntoa(addr);
}


WSACleanup();

return &quot;Done&quot;;
}

I tried this, passing 0 and 1 as the paramater, but it returns &quot;80.13.127.0&quot;. Any number other than 0 or 1 returns &quot;Done&quot;.

My local address is 192.168.0.1
My internet address is dynamic, but usually 144.13x.xxx.xxx

What exactly is the ipnum paramater for?

By the way 2ffat, Thread101-18803 is no good.

2ffat,
This time you swapped the 3 and the 1
The correct thread should be Thread101-188031

basically, it will return all of thhe IP addresses on your machine, hence the &quot;ipnum&quot;, the number of the IP address that you want. To get your IP address, make ipnum '0'. If there is no IP, then it will return &quot;Done&quot;. Cyprus
