我有一个动态IP地址,实际上我可以从我的路由器页面(http://192.168.1.1)点击释放然后续约来更改它。
我可以通过curl向http://192.168.1.1页面发出HTTP请求,但这只解决了使用该路由器的计算机的问题。
因此,我想知道是否有一种方法可以通过c ++更新我的IP地址,而不通过路由器页面(192.168.1.1)。
我也尝试过命令行,但没有成功的结果。我尝试的代码如下:

我已经启用了DHCP服务器,具体数值如下:
DHCP服务状态
DHCP状态:已启用
DHCP初始IP地址:192.168.1.2
DHCP结束IP地址(保留供内部使用):192.168.1.254
我需要在Windows XP和Windows 7平台上运行我的程序。
谢谢您的帮助。
DHCPRELEASE
数据包并请求一个新的IP地址。 - RockiDHCPRELEASE
? - Carmeipconfig /release [<Adapter>]
或ipconfig /release6 [<Adapter>]
https://technet.microsoft.com/en-us/library/dd197434.aspx 如果你真的想用C++来做,那就使用WinApiIpReleaseAddress
https://msdn.microsoft.com/en-us/library/windows/desktop/aa366056%28v=vs.85%29.aspx - Rockiipconfig /release
和ipconfig /renew
,但它们不起作用。现在我将尝试学习函数 IPReleaseAddres 和 IPRenewAddres。希望这不会太难 :D - Carme
