环境：win7_64 + VS2012 +Qt5

利用QT获取本机IP地址，示例代码如下

	bool bFindLocalIP = false;
        QString qsLocalIP;
    //局域网网段192.168.0.0/16，表示192.168.0~255.0~255.可以根据实际情况设置
	QPair<QHostAddress,int> rangeIp = QHostAddress::parseSubnet("192.168.0.0/16");
	QList<QNetworkInterface> networkInterface = QNetworkInterface::allInterfaces();
	QList<QNetworkInterface>::const_iterator itFace = networkInterface.begin();
	for(; itFace != networkInterface.end(); itFace++)
	{
		if ((*itFace).isValid() && !(*itFace).humanReadableName().contains("VMware"))
		{
			QList<QNetworkAddressEntry> addressEntriesList = (*itFace).addressEntries();
			QList<QNetworkAddressEntry>::const_iterator itEntries = addressEntriesList.begin();
			for(; itEntries != addressEntriesList.end(); itEntries++)
			{
				if( itEntries->ip().protocol() == QAbstractSocket::IPv4Protocol &&
					itEntries->ip().isInSubnet(rangeIp))
				{
					qsLocalIP = itEntries->ip().toString();
					bFindLocalIP = true;
					break;
				}
			}

			if (bFindLocalIP)
			{
				break;
			}
		}
	}
