我也要 关注 + 加入社区在网上这样来获取MAC地址和IP：
QList<QNetworkInterface>list = QNetworkInterface::allInterfaces();
foreach(QNetworkInterface interface, list) //遍历每个网络接口
{
//硬件地址
qDebug() << "HardwareAddress:" << interface.hardwareAddress();
//获取IP地址条目列表，每个条目中包含一个IP地址，一个子网掩码和一个广播地址
QList<QNetworkAddressEntry>entryList = interface.addressEntries();
foreach(QNetworkAddressEntry entry, entryList)//遍历每一个IP地址条目
{
//IP地址
qDebug() << "IP Address: " << entry.ip().toString();
//子网掩码
qDebug() << "Netmask: " << entry.netmask().toString();
//广播地址
qDebug() << "Broadcast: " << entry.broadcast().toString();
}
}
运行的结果是这样的，这是在win7系统下运行的结果
HardwareAddress: "58:91:CF:33:A6:71"
IP Address: "FE80::D0B8:3B91:5BB3:CCA4%13"

Broadcast: ""
问题是，我怎样来提取有效的MAN地址和IP呢，我通过MAC地址扫描器得到第一个MAC地址和IP是有效的，其他的 哪些怎么去屏蔽掉呢。
QList<QNetworkInterface>list = QNetworkInterface::allInterfaces();
foreach(QNetworkInterface interface, list) //遍历每个网络接口
{
//硬件地址
qDebug() << "HardwareAddress:" << interface.hardwareAddress();
//获取IP地址条目列表，每个条目中包含一个IP地址，一个子网掩码和一个广播地址
QList<QNetworkAddressEntry>entryList = interface.addressEntries();
foreach(QNetworkAddressEntry entry, entryList)//遍历每一个IP地址条目
{
//IP地址
qDebug() << "IP Address: " << entry.ip().toString();
//子网掩码
qDebug() << "Netmask: " << entry.netmask().toString();
//广播地址
qDebug() << "Broadcast: " << entry.broadcast().toString();
}
}
