Windows xp修改IP地址
博客说明

文章所涉及的资料来自互联网整理和个人总结，意在于个人学习和经验汇总，如有什么地方侵权，请联系本人删除，谢谢！

步骤
打开网上邻居，找到属性

在本地连接找到属性

进入配置IP协议

修改完地址点击确定

打开终端查看ip地址

万能的网络
以及勤劳的自己

因为以太网属性为空白，修改不了IP了又不想重装系统只能使用命令的方式进行临时解决了



以管理员的身份运行cmd，使用命令的方式进行修改IP和DNS服务器



修改IP地址：

netsh  interface ip set address “以太网 3” static 192.168.200.130 255.255.255.0 192.168.200.1

修改DNS服务器地址：

netsh  interface ip set dns “以太网 3” static 8.8.8.8



ps：“以太网 3”，根据自己电脑的网络适配器名称进行填写
如果不想使用静态IP也可以使用命令自动获取IP

自动获取IP：
netsh  interface ip set address "WLAN"  source=dhcp

自动获取DNS服务器：
netsh  interface ip set dns "WLAN" source=dhcp

读取Windows的IP地址有三种方法：
QT的QNetworkInterface   
IPHlpApi
QT的QSettings读注册表
修改windows的IP地址使用 netsh
netsh interface ipv4 set address name = "以太网" source = static address = 192.168.0.106 mask = 255.255.255.0 gateway = 192.168.0.1 
代码：
QT的QNetworkInterface   
void QtNetwork::initNetwork()
{
	ui.comboBox->clear();

	QString text;
	QTextStream out(&text);
	QList<QNetworkInterface> ifaceList = QNetworkInterface::allInterfaces();
	for (int i = 0; i < ifaceList.count(); i++)
	{
		QNetworkInterface var = ifaceList.at(i);
		out << QString::fromLocal8Bit("########## 设备%1 ############").arg(i) << endl;
		out << QString::fromLocal8Bit("接口名称：") << var.humanReadableName() << endl;
		out << QString::fromLocal8Bit("设备名称：") << var.name() << endl;
		out << QString::fromLocal8Bit("硬件地址：") << var.hardwareAddress() << endl;

		ui.comboBox->addItem(var.name());

		out << QString::fromLocal8Bit("IP地址列表：") << endl;
		// 读取一个IP地址的关联信息列表
		QList<QNetworkAddressEntry> entryList = var.addressEntries();
		for(int j = 0; j < entryList.count(); j++)
		{
			QNetworkAddressEntry entry = entryList.at(j);
			out << QString::fromLocal8Bit("%1_地址：").arg(j) << endl;
			out << QString::fromLocal8Bit(" IP地址：") << entry.ip().toString() << endl;
			out << QString::fromLocal8Bit(" 子网掩码：") << entry.netmask().toString() << endl;
			out << QString::fromLocal8Bit(" 广播地址：") << entry.broadcast().toString() << endl;
		}
	}

	ui.textEdit->setPlainText(text);
}
IPHlpApi
void QtNetwork::initNetwork_IPHlpApi()
{
	QString text;
	QTextStream out(&text);

	//IP_ADAPTER_INFO结构体
	PIP_ADAPTER_INFO pIpAdapterInfo = NULL;
	pIpAdapterInfo = new IP_ADAPTER_INFO;

	//结构体大小
	unsigned long ulSize = sizeof(IP_ADAPTER_INFO);

	//获取适配器信息
	int nRet = GetAdaptersInfo(pIpAdapterInfo, &ulSize);

	if (ERROR_BUFFER_OVERFLOW == nRet)
	{
		//空间不足，删除之前分配的空间
		delete[]pIpAdapterInfo;

		//重新分配大小
		pIpAdapterInfo = (PIP_ADAPTER_INFO) new BYTE[ulSize];

		//获取适配器信息
		nRet = GetAdaptersInfo(pIpAdapterInfo, &ulSize);

		//获取失败
		if (ERROR_SUCCESS != nRet)
		{
			if (pIpAdapterInfo != NULL)
			{
				delete[]pIpAdapterInfo;
			}
			return;
		}
	}

	//MAC 地址信息
	char szMacAddr[20];
	//赋值指针
	PIP_ADAPTER_INFO pIterater = pIpAdapterInfo;
	int i = 0;
	while (pIterater)
	{
		out << QString::fromLocal8Bit("########## 设备%1 ############").arg(i) << endl;
		out << QString::fromLocal8Bit("网卡名称：") << pIterater->AdapterName << endl;
		out << QString::fromLocal8Bit("网卡描述：") << pIterater->Description << endl;

		sprintf_s(szMacAddr, 20, "%02X-%02X-%02X-%02X-%02X-%02X",
			pIterater->Address[0],
			pIterater->Address[1],
			pIterater->Address[2],
			pIterater->Address[3],
			pIterater->Address[4],
			pIterater->Address[5]);

		out << QString::fromLocal8Bit("MAC 地址：") << szMacAddr << endl;

		out << QString::fromLocal8Bit("IP地址列表：") << endl;

		//指向IP地址列表
		int j = 0;
		PIP_ADDR_STRING pIpAddr = &pIterater->IpAddressList;
		while (pIpAddr)
		{
			out << QString::fromLocal8Bit("%1_地址：").arg(j) << endl;
			out << QString::fromLocal8Bit(" IP地址：") << pIpAddr->IpAddress.String << endl;
			out << QString::fromLocal8Bit(" 子网掩码：") << pIpAddr->IpMask.String << endl;

			//指向网关列表
			PIP_ADDR_STRING pGateAwayList = &pIterater->GatewayList;
			while (pGateAwayList)
			{
				out << QString::fromLocal8Bit(" 网关：") << pGateAwayList->IpAddress.String << endl;

				pGateAwayList = pGateAwayList->Next;
			}

			pIpAddr = pIpAddr->Next;
			j++;
		}

		pIterater = pIterater->Next;
		i++;
	}

	//清理
	if (pIpAdapterInfo)
	{
		delete[]pIpAdapterInfo;
	}

	ui.textEdit_2->setPlainText(text);
}
QT的QSettings读注册表
void QtNetwork::initNetwork_reg()
{
	QString text;
	QTextStream out(&text);

	QSettings reg("HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\services\\Tcpip\\Parameters\\Interfaces\\", QSettings::NativeFormat);
	QStringList groupsList = reg.childGroups();
	qDebug() << "read size:" << groupsList.size();

	int i = 0;
	foreach(QString group, groupsList)
	{
		out << QString::fromLocal8Bit("########## 设备%1 ############").arg(i) << endl;
		out << QString::fromLocal8Bit("设备名称：") << group << endl;

		reg.beginGroup(group);

		QString ip = reg.value("IPAddress").toString();
		if (!ip.isEmpty())
		{
			out << QString::fromLocal8Bit(" IP地址：") << ip << endl;
		}

		QString netmask = reg.value("SubnetMask").toString();
		if (!netmask.isEmpty())
		{
			out << QString::fromLocal8Bit(" 子网掩码：") << netmask << endl;
		}

		QString gateway = reg.value("DefaultGateway").toString();
		if (!gateway.isEmpty())
		{
			out << QString::fromLocal8Bit(" 网关:") << gateway << endl;
		}

		reg.endGroup();
		i++;
	}

	ui.textEdit_3->setPlainText(text);
}

修改IP地址
void QtNetworkEditDlg::on_pushButton_ok_clicked()
{
	QString name = m_interface.humanReadableName();
	QString ip = ui.lineEdit_ip->text();
	QString netmask = ui.lineEdit_netmask->text();

	QProcess cmd(this);

	// netsh interface ipv4 set address name = "以太网" source = static 
	// address = 192.168.0.106 mask = 255.255.255.0 gateway = 192.168.0.1 gwmetric = 0
	QString command = "netsh interface ipv4 set address name = "
		+ name + " source = static address = " + ip
		+ " mask = " + netmask;
	cmd.start(command);
	cmd.waitForFinished();

	accept();
}

在管理员模式下输入如下命令即可设置静态ip地址：
netsh int ip set addr "本地连接" static ip mask gateway
