    Code:
    #include <cstdlib>
    
    int main()
    {
        system( "ipconfig" );
        return 0;
    }
    or you can save some time and just run IPCONFIG from a command line.

    It only has to output your extern IP, so i can check if it 0.0.0.0 fo example

    Do you just want to check if you have an internet connection?

    What's the end goal?

    I only want specific IP address to be able to use my program. so i have to check if the IP is for example 0.0.0.0

    Here's one of a few ways to enumerate your interfaces:

    Go to http://www.ipchicken.com

    That shows your REAL "external" IP address, as far as the rest of the Internet is concerned.

    But that's not the IP address of MY computer, but of the other side of the set of router/firewall/proxy server stuff that ends up issuing the EXTERNAL IP-address. I can have two dozen machines this side of the network equipment, all with their completely separate IP addresses.

    Also note that relying on IP address to stay static won't work if you use a DHCP server - then the address is likely to change every now and again - particularly if the machine is shut down and rebooted a day or two later, it's VERY likely to have a differnet IP-address.
