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();
     }
     
}

Sorry?

In what way not fast? It uses your platform mechanisms so it should be exactly the same in speed as other DNS lookups.

"dig" uses libnsl and you can do everything with it (including AXFR transfers) so I can't agree with what you said.

dig is part of bind-utils (or simmilar) package and is under GPL, so yes, sources are available.
