qt get local ip address code example

Example: qt qet name of PC and ipaddres

QString localhostname =  QHostInfo::localHostName();
   QString localhostIP;
   QList<QHostAddress> hostList = QHostInfo::fromName(localhostname).addresses();
   foreach (const QHostAddress& address, hostList) {
       if (address.protocol() == QAbstractSocket::IPv4Protocol && address.isLoopback() == false) {
            localhostIP = address.toString();
       }
   }
   QString localMacAddress;
   QString localNetmask;
   foreach (const QNetworkInterface& networkInterface, QNetworkInterface::allInterfaces()) {
       foreach (const QNetworkAddressEntry& entry, networkInterface.addressEntries()) {
           if (entry.ip().toString() == localhostIP) {
               localMacAddress = networkInterface.hardwareAddress();
               localNetmask = entry.netmask().toString();
               break;
           }
       }
   }
   qDebug() << "Localhost name: " << localhostname;
   qDebug() << "IP = " << localhostIP;
   qDebug() << "MAC = " << localMacAddress;
   qDebug() << "Netmask = " << localNetmask;
