(Java) Find My External Public IP Address
To find your external public IP address (not your LAN IP address, such as 192.168.1.* or 172.16.16.*, etc), your application would need to send a request to an HTTP server that can report back on the origin IP address. You can easily write a simple script on your own web server to do it, or you can use a service such as ipify.org.
This example shows how to send a request to the ipify.org endpoint to get your public IP address. For more information, see https://www.ipify.org/
import com.chilkatsoft.*;
public class ChilkatExample {
static {
try {
System.loadLibrary("chilkat");
} catch (UnsatisfiedLinkError e) {
System.err.println("Native code library failed to load.\n" + e);
System.exit(1);
}
}
public static void main(String argv[])
{
CkHttp http = new CkHttp();
String my_ip_address = http.quickGetStr("https://api.ipify.org");
if (http.get_LastMethodSuccess() == false) {
System.out.println(http.lastErrorText());
return;
}
System.out.println("My Public IP Address: " + my_ip_address);
}
}
