Bueno, como dice el titulo con el siguiente metodo puedes obtener tu Ip externa como si del DynDNS se tratara. Lo primero sera subir el fichero *.PHP a un servidor que sea compatible con el PHP.
PHP:/* Esta es una pequeña funcion que devuleve la IP
Actual siempre y cuando se navege desde el navegador 'karcrack'
*/
<?PHP
$Nav = $_SERVER['HTTP_USER_AGENT'];
if ($Nav == "karcrack")
{
echo $_SERVER['REMOTE_ADDR'];
}
else
{
echo '127.0.0.1';
}
?>Esta funcion comprueba que el navegador con el que se navega sea 'karcrack', por supuesto esto se puede modificar :xD
VB:'Esto se pone siempre xD

Call SetHTTPLib

End FunctionBueno, aqui esta todo bien explicado... la funcion se llama de esta forma:
msgbox ObIp ("URL_DONDE_ESTA_EL_SCRIPT_EN_PHP")
Saludos :D
Gracias , por el aporte.
