I Knitting this piece of code to discovery if client is Connected to Network...
But how i can check if gateway && dns resolve correct?
similar to php http://php.net/gethostbyname or http://php.net/dns_get_mx
without Qprocess host dig ....


Qt Code: 
  1. static inline bool NetworkEnable() {
  2.  
  3.     bool validip = false;
  4.     QList<QHostAddress> addrlist = QNetworkInterface::allAddresses();
  5.     int o = -1;
  6.     foreach(QHostAddress addr, addrlist){
  7.     o++;
  8.     QNetworkInterface hop = QNetworkInterface::interfaceFromIndex(o);
  9.     QString mach = hop.hardwareAddress(); 
  10.     QString name = hop.name();
  11.     QString oneip = addr.toString();
  12.         if (!oneip.contains("127.")) {
  13.          bool actual = hop.isValid();
  14.             if (actual) {
  15.              validip = true;  
  16.             }
  17.          ////////qDebug() << "flags -> " <<  hop.flags();
  18.          //////////qDebug() << "pi -> " << oneip << " valid ->" << validip << " MACADRESS->" << mach << " name ->" << name;
  19.         }
  20.     }
  21.    //////qDebug() << "validip -> " <<  validip;
  22. return validip;
  23. }
