How about just using libnsl?

Why http://doc.trolltech.com/3.2/qdns.html is not running? on QT4 is comming new??

QHostInfo::lookupHost("qtcentre.org",this, SLOT(LookedUp(QHostInfo))); 
 
void DnsQuery::LookedUp( const QHostInfo &host )
{
    if (host.error() != QHostInfo::NoError) {
         qDebug() << "Lookup failed:" << host.errorString();
         return;
     }
 
     foreach (QHostAddress address, host.addresses()) {
         qDebug() << "Found address:" << address.toString();
     }
 
}

QHostInfo::lookupHost("qtcentre.org",this, SLOT(LookedUp(QHostInfo))); 

void DnsQuery::LookedUp( const QHostInfo &host )
{
    if (host.error() != QHostInfo::NoError) {
         qDebug() << "Lookup failed:" << host.errorString();
         return;
     }

     foreach (QHostAddress address, host.addresses()) {
         qDebug() << "Found address:" << address.toString();
     }
     
}

This is not fast!

libnsl dont have TTL or MX prior..
