QT 获取本机IP地址 子网掩码 网卡

QList<QNetworkInterface> interfaceList = QNetworkInterface::allInterfaces();

for (int i = 0; i < interfaceList.count(); i++)

{

QNetworkInterface interf = interfaceList.at(i);

interf.humanReadableName(); //接口名称（网卡）

// 读取一个IP地址列表

QList<QNetworkAddressEntry> entryList = interf.addressEntries();

for(int j = 0; j < entryList.count(); j++)

{

QNetworkAddressEntry entry = entryList.at(j);

QString ip = entry.ip().toString();//IP地址

QString mask = mask().toString(); //子网掩码

QString bcast = entry.broadcast().toString();//广播地址

}

}
