Get local IP address in Qt

Question

Is there a cross-platform way to get the local IP address (i.e. something that looks like 192.168.1.49) of the computer using Qt?

I want to make an FTP

Answer 1

Use QNetworkInterface::allAddresses()

const QHostAddress &localhost = QHostAddress(QHostAddress::LocalHost);
for (const QHostAddress &address: QNetworkInterface::allAddresses()) {
    if (address.protocol() == QAbstractSocket::IPv4Protocol && address != localhost)
         qDebug() << address.toString();
}
