QHostAdress behaves differently with Qt 5.4.1

[_rth_]

Hello.

Following simple application gives different results when compiled against Qt 4.8.5 and Qt 5.4.1:

#include <QCoreApplication>
#include <QHostAddress>
#include <QDebug>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QString ip("1");
    //QString ip("x");

    QHostAddress adr;
    if (adr.setAddress(ip))
        qDebug() << "OK";
    else
        qDebug() << "NOK";

    if (adr.isNull())
        qDebug() << "NOK";
    else
        qDebug() << "OK";

    //return a.exec();
}

Result from Qt 4.8.5 build:
NOK
NOK

Result from Qt 5.4.1 build:
OK
OK

Is this a bug? Or I am doing something wrong?
