IP Addresse des Computers herausfinden

[Dezipaitor]

hier siehst du den Code, der dir den Computername und
die IP-Addressen (alle LAN und WAN-Addressen)
des Computers anzeigt.

man braucht dazu die Library : ws2_32.lib

#include <iostream>
#include <stdlib.h>
#include <vector>
#include <string>
#include "winsock.h"

using namespace std;

typedef vector<string> STRINGS;

long GetHostIP(STRINGS &hosts)
{
	char name[255];
	gethostname((char*)&name,sizeof(name));

	struct hostent *host;
	if ((host = gethostbyname((char*)&name)) == NULL)
	{
		return -1;
	}

	string anhost;
	anhost = host->h_name; //Der Computername
	hosts.push_back(anhost);

//ermittelt alle Addressen des Computers
	int i = 0;
	while (host->h_addr_list[i] > 0)
	{
		in_addr INET;
		INET.S_un.S_addr = *((unsigned long*)host->h_addr_list[i]);
		hosts.push_back(inet_ntoa(INET));
		i++;
	}
}

int main(int argc, char *argv[])
{
    WSADATA WSAData;
    WSAStartup (MAKEWORD(1,1), &WSAData);

    STRINGS IPs;
	GetHostIP(IPs);

	int s1 = IPs.size();
	string s2;
	for (int i = 0; i < s1; i++)
	{
		cout << IPs[i] << endl;
	}
  return 0;
}

Wenn jemand, weiß wie man zwischen LAN und WAN Addressen unterscheidet - bitte mail an : dezipaitor at gmx.de
