Hello Expert I Have New Problem

I Want To Get All Connected Devices List And It's IP Address Over LAN Network

My Try Is :

                           QList<QNetworkInterface> interfaces = QNetworkInterface::allInterfaces();
                          
                              qDebug() << interfaces;                              
                              for (int i = 0; i < interfaces.count(); i++)                              
                              {                              
                                  QList<QNetworkAddressEntry> entries = interfaces.at(i).addressEntries();
                                                                                     
                                  for (int j = 0; j < entries.count(); j++)                              
                                  {                              
                                      if (entries.at(j).ip().protocol() == QAbstractSocket::IPv4Protocol)                              
                                      {                                                            
                                          qDebug() << entries.at(j).ip().toString();                              
                                          ui->listWidget->addItem(entries.at(j).ip().toString());                              
                                      }                              
                                  }

My Other Try Is :

                                    const QHostAddress &localhost = QHostAddress(QHostAddress::AnyIPv4);
                                
                                    for (const QHostAddress &address: QNetworkInterface::allAddresses())                                    
                                    {                                    
                                        if (address.protocol() == QAbstractSocket::IPv4Protocol && address != QHostAddress(QHostAddress::AnyIPv4))                                    
                                        {                                    
                                            qDebug() << address.toString();                                    
                                        }                                    
                                    }

Hey,

Your first code provides me with the correct results,

Are you sure you are connected to the router etc?
And that you are not on a restricted network, limiting you from accessing the other connected devices?

"xxx.xxx.xxx.xxx"
"xxx.xxx.xxx.xxx"
"xxxxxx.xx.xxx"
"xxx.xxx.x.xxx"
"xxx.xxx.xxx.xxx"
"127.0.0.1"

Please clarify if you want to list the IP addresses of other devices connected to the same LAN as your Qt app is running?
