您的任何系统是否曾经弹出有关您的 IP 地址冲突的错误消息？当您将系统、智能手机或任何此类设备连接到本地网络时，内部会发生什么；他们都得到一个唯一的IP地址。这样做的主要目的是为网络及其元素提供重要的寻址技术。这有助于区分同一网络上的每个设备并以数字方式相互交谈。
IP地址(IP address)冲突虽然不是经常发生的事情，但确实是个问题，给用户带来了很大的困扰。当同一网络中的 2 个或更多系统、连接端点或手持设备最终被分配相同的 IP 地址时，就会发生 IP 地址冲突。这些端点可以是PC(PCs)、移动设备或其他网络实体。当 2 个端点之间发生此 IP 冲突时，会导致无法使用 Internet 或连接到 Internet。
IP 地址冲突是如何发生的？(How do IP Address Conflicts happen?)
设备可以通过多种方式获取 IP 地址冲突。
✓ 当系统管理员在LAN上分配 2 个具有相同静态 IP 地址的系统时。
✓ 本地DHCP服务器分配一个 IP 地址，并且系统管理员在分配本地(DHCP)DHCP网络范围内的静态 IP 时分配了相同的 IP 地址的情况。
✓ 当您的网络的DHCP服务器出现故障并最终将相同的动态地址分配给多个系统时。
✓ IP 冲突也可能以其他形式发生。当系统配置有各种适配器时，系统可能会遇到与自身的 IP 地址冲突。
识别 IP 地址冲突(Recognizing IP Address Conflicts)
错误警告或有关 IP 冲突的指示将根据受影响的机器类型或系统正在运行的操作系统出现。在许多基于Microsoft Windows 的系统上，您将收到以下弹出错误消息：
“刚刚配置的静态 IP 地址已经在网络上使用。请重新配置不同的 IP 地址。(The static IP address that was just configured is already in use on the network. Please reconfigure a different IP address.)”
对于新的Microsoft Windows系统，您会在(Microsoft Windows)任务栏(Taskbar)下方收到一个关于动态 IP 冲突的气球错误消息：
“与网络上的另一个系统存在 IP 地址冲突。(There is an IP address conflict with another system on the network.)”
在一些旧的Windows机器上，警告消息或信息性消息可能会出现在弹出窗口中，内容是：
“系统检测到IP地址冲突……(The system has detected a conflict for IP address…) ”
“ Windows 检测到 IP 地址冲突。(Windows has detected an IP address conflict.)”
如何修复 IP 地址冲突(How to Fix IP Address Conflict)
因此，不要浪费任何时间，让我们看看如何(how to fix IP Address Conflict in Windows)在下面列出的教程的帮助下修复 Windows 中的 IP 地址冲突。
确保 创建一个还原点(create a restore point) 以防万一出现问题。
方法 1：重新启动调制解调器或无线路由器(Method 1: Reboot Your Modem or Wireless Router)
通常，简单的重启可以立即解决此类IP地址冲突问题。有两种方法可以重新启动调制解调器或无线路由器：
1.打开浏览器登录(Log)管理员管理页面（在地址栏中输入以下任何 IP - 192.168.0.1、192.168.1.1 或 192.168.11.1(192.168.0.1, 192.168.1.1, or 192.168.11.1)），然后查找Management -> Reboot.
2. 拔下电源线或按下电源按钮关闭电源，过一段时间再打开。
重新启动调制解调器或路由器后，连接计算机并检查是否能够修复 IP 地址冲突问题。( Fix IP Address Conflict issue or not.)
Method 2: Flush DNS and Reset TCP/IP
1.打开命令提示符(Command Prompt)。用户可以通过搜索“cmd”然后按 Enter 来执行此步骤。
2. 现在输入以下命令并在每个命令后按Enter ：
ipconfig /release
ipconfig /flushdns
ipconfig /renew
3.再次(Again)，打开Admin Command Prompt并键入以下内容，然后在每个之后按回车：
ipconfig /flushdns
nbtstat –r
netsh int ip reset
netsh winsock reset
4. 重新启动以应用更改。刷新DNS似乎可以修复 Windows 检测到 IP 地址冲突错误。(fix Windows has detected an IP address conflict error.)
方法 3：手动为您的 Windows 计算机设置静态 IP 地址(Method 3: Set Static IP Address For Your Windows Computer Manually)
如果上述方法无法解决 IP 地址冲突的问题，建议您手动为您的计算机配置一个静态 IP 地址。为此，步骤如下：
1. 在任务栏右侧，右键单击“网络(Network)”图标，然后单击“打开网络和 Internet 设置(Open Network & Internet settings)”选项。
2. 现在设置(Settings)窗口将打开，点击相关设置下的“网络和共享中心”。(Network and Sharing Center)
3. 现在，选择您当前正在使用的“网络适配器”（以及出现此问题的网络适配器）。
4.点击(Click)已有的连接，会弹出一个新的对话框。单击(Click)“属性(Properties)”选项。
5. 现在，双击“ Internet Protocol Version 4 (TCP/IPv4) ”选项。
6.它将允许您根据您的调制解调器或路由器的详细信息配置您的静态IP。以下(Below)只是其中一种情况的示例：
注意：(Note:) 如果您的调制解调器/路由器的 IP 地址不同，例如 192.168.11.1，那么您的静态 IP 地址需要遵循其格式，例如 192.168.11.111。否则，您的Windows计算机将无法连接到网络。
IP address: 192.168.1.111
Subnet mask: 255.255.255.0
Default gateway: 192.168.1.1
Preferred DNS server: 8.8.8.8
Alternative DNS server: 8.8.4.4
7. 填写完所有必需的详细信息后，单击确定并重新启动您的 PC。

How to Fix IP Address Conflict
Have аny of your systems ever popped up with an error message cоncerning уour IP address conflict? What internally happens is when you link your system, smart-phones, or any such devices tо a local netwоrk; they all get a unique IP address. The mаin purposе of this is to grant a significant addressing technique for the network & itѕ elements. This helps in distіnguishing each device on the same nеtwork and cоnverse to each other digitally.
Even though it is not something that occurs frequently, IP address conflicts are authentic problems and troubles a lot to the users. Conflicting IP address happens when 2 or more systems, connection end-points or hand-held devices in the same network wind up being allocated the same IP address. These endpoints can be either PCs, mobile devices, or other network entities. When this IP conflict occurs between 2 endpoints, it causes trouble to use the internet or connect to the internet.
How do IP Address Conflicts happen?
There are different ways a device can acquire IP address confliction.
✓ When a system administrator allocates 2 systems with the same static IP address on a LAN.
✓ Cases, when your local DHCP server assigns an IP address and that same IP address is assigned by system administrator while allocating static IP within the range of local DHCP network.
✓ When the DHCP servers of your network malfunction and end up assigning the same dynamic address to multiple systems.
✓ IP conflicts can also occur in other forms. A system may experience an IP address clash with itself when that system is configured with various adapters.
Recognizing IP Address Conflicts
The error warning or indications regarding IP conflicts will arise based on the type of machine affected or the OS that the system is running. On a lot of Microsoft Windows-based systems, you will obtain the following pop up error message:
“The static IP address that was just configured is already in use on the network. Please reconfigure a different IP address.”
For the new Microsoft Windows systems, you receive a balloon error pop up below in the Taskbar regarding dynamic IP conflicts saying:
“There is an IP address conflict with another system on the network.”
On some old Windows machines, a warning message or informative message may appear in a pop-up window saying:
“The system has detected a conflict for IP address…”
“Windows has detected an IP address conflict.”
How to Fix IP Address Conflict
So without wasting any time, let’s see how to fix IP Address Conflict in Windows with the help of the below-listed tutorial.
Make sure to create a restore point just in case something goes wrong.
Method 1: Reboot Your Modem or Wireless Router
Usually, a simple rebooting can sort out such IP address conflict issue immediately. There are 2 means one can restart the modem or wireless router:
1. Log into your administrator management page by opening the browser (type in address bar any of the following IP – 192.168.0.1, 192.168.1.1, or 192.168.11.1) and then look for Management -> Reboot.
2. Turn off the power by unplugging the power cable or pressing its power button and then turn back on after some time.
Once you restart your modem or router, connect your computer and check whether you’re able to Fix IP Address Conflict issue or not.
Method 2: Flush DNS and Reset TCP/IP
1. Open Command Prompt. The user can perform this step by searching for ‘cmd’ and then press Enter.
2. Now type the following command and press Enter after each one:
ipconfig /release
ipconfig /flushdns
ipconfig /renew
3. Again, open Admin Command Prompt and type the following and hit enter after each one:
ipconfig /flushdns
nbtstat –r
netsh int ip reset
netsh winsock reset
4. Reboot to apply changes. Flushing DNS seems to fix Windows has detected an IP address conflict error.
Method 3: Set Static IP Address For Your Windows Computer Manually
If the above method fails in fixing the issue of IP address conflict, it is recommended to configure a static IP address for your computer manually. For this, the steps are as follows:
1. At the right side of your taskbar, right-click on the “Network” icon and then click the “Open Network & Internet settings” option.
2. Now Settings window will open, click on “Network and Sharing Center” under Related settings.
3. Now, select the “network adapter” which you are currently using (as well as the one which is getting this issue).
4. Click on the existing connection, it will pop up with a new dialog box. Click the “Properties” option.
5. Now, double click on “Internet Protocol Version 4 (TCP/IPv4)” option.
6. It will allow you to configure your static IP based on your details of modem or router. Below is just an example in one of such cases:
Note: If the IP address of your modem/router is different, such as 192.168.11.1, then your static IP address needs to follow its form, for example, 192.168.11.111. Otherwise, your Windows computer won’t be able to connect to the network.
IP address: 192.168.1.111
Subnet mask: 255.255.255.0
Default gateway: 192.168.1.1
Preferred DNS server: 8.8.8.8
Alternative DNS server: 8.8.4.4
7. Once fill in all the required details, click OK and reboot your PC.
