QHostInfo IP Detection under Vista

[visor_ua]

Next code is woring well under all win system before vista.

QString        ipAddress;
QHostInfo info = QHostInfo::fromName( QHostInfo::localHostName() );
QList<QHostAddress> listAddr= info.addresses();
ipAddress = listAddr.first().toString();

QString        ipAddress;
QHostInfo info = QHostInfo::fromName( QHostInfo::localHostName() );
QList<QHostAddress> listAddr= info.addresses();
ipAddress = listAddr.first().toString();

Under vista this code giving IPv6 addr. (FE80:0:0:0:4B1:.....)
Any ideas?

Try to convert it to ipv4 with QHostInfo::toIPb4Address.
You should construct a new QHostInfo from that value.

To make it work on both vista and xp you can test the protocol with QHostInfo::protocol and make the necessary conversion, if necessary.

Yes. Solved using protocol() method

QHostInfo info = QHostInfo::fromName( QHostInfo::localHostName() );
QList<QHostAddress> listAddr= info.addresses();
    for( int i = 0; i < listAddr.size(); i ++ )
    {
        if( listAddr.at(i).protocol() == QAbstractSocket::IPv4Protocol )
        {
            ipAddress = listAddr.at(i).toString();
            break;
        }        
    }

QHostInfo info = QHostInfo::fromName( QHostInfo::localHostName() );
QList<QHostAddress> listAddr= info.addresses();
    for( int i = 0; i < listAddr.size(); i ++ )
    {
        if( listAddr.at(i).protocol() == QAbstractSocket::IPv4Protocol )
        {
            ipAddress = listAddr.at(i).toString();
            break;
        }        
    }
