Why can’t my computer’s IP address be changed? PHP editor Zimo will provide you with an in-depth analysis of this issue. Have you ever encountered the problem that the IP address of your computer cannot be changed at will, which greatly limits your network connection and operations? In order to solve this problem, this article will delve into the reasons behind the inability to change the IP address and provide a practical guide to help you easily change the IP address to meet your network needs.

Why can’t I change my computer’s IP address?

1. Why can’t I change my computer’s IP address?

This depends on the settings of the upper-level router. If address mapping is set up, the IP address cannot be changed at will. In network settings, sometimes in order to improve network security or facilitate network management, network administrators will add policy management to routing devices.

For example, restricting access to only certain specific IPs; or binding IP addresses or ports based on MAC addresses; such a management method does not allow users to change IP addresses at will.

If you change the IP address at will, it will cause the machine to be unable to access the Internet, or it will cause an IP address conflict. If it conflicts with the client address, it is okay, but it will only cause one device to be unable to access the network; if it conflicts with the address of the router or server , then basically the entire network will collapse.

2. How to change the IP address of my computer to a foreign one?

1. ADSL dial-up to change IP address

This method of changing IP address is actually the broadband dial-up we usually use. The IP address obtained by dial-up is different every time, but this method cannot be used for fiber-optic broadband, and using this When changing an IP address using this method, generally only the last number segment will be changed, and the numbers in the first three number segments will not change. The disadvantage of this method is that it is not stable enough. Sometimes you need to dial multiple times to successfully change the IP address, which wastes a lot of time.

2. Restart the wifi router to change the IP

Directly unplug the wifi router and plug it in or open 192.168.1.1 to log in (the username and password are usually admin), click System Tools - Restart Router.

3. Virtual private network changing IP address

The so-called virtual private network changing IP address actually uses a virtual private network to switch the user’s IP address. This method of changing IP address generally requires Users with IP addresses from abroad or from Hong Kong, Macao and Taiwan

4. Agent IP software to change the IP address

This can be said to be a more commonly used method. Users only need to select their own proxy IP service provider on the network, select the node they need, and then switch IP addresses easily. However, the current proxy IP market is relatively chaotic. Users need to be cautious when choosing proxy IPs, pay after testing and confirmation, and try to choose a well-known brand like IPIDEA.

3. How to solve the problem that the IP address of my computer does not match the actual IP address?

Your practical computer should be an IP automatically obtained by the unlimited link. In this case, your IP will change. There will be a delay in the IP you check online, so there will be a situation where the two IPs do not match. Should you still use The command ipconfig can be used to find out more accurately. If you want the computer to obtain a fixed IP, just fix the IP address on the router. Another method is to use a wired one and the IP will be fixed.

4. How do I map my computer’s IP on the switch?

The switch is not connected to the Internet. Please set up DMZ mapping on the router and set the IP to the IP address of your computer.

5. How to check the 12-digit IP address on the computer? It needs 12 digits. The IP of my computer is only 10 digits at most. I want to play local network connection?

Windows+r key brings up the run window, enter cmd and then enter ipconfig in the pop-up window. Find the IP address under the network port you are using. For example, if yours is 192.168.1.50, then you enter 192.168.001.050

Six , How can I change my computer’s static IP to a dynamic IP?

  1. Select the "Network" icon on the desktop, right-click menu: Properties.

 2. Click Ethernet. 3. Click Properties. 4. Click IP protocol. 5. Click to automatically obtain an IP address and DNS.

7. My computer always prompts that the IP address is duplicated, but my computer automatically assigns IP addresses and they are different?

Click the "Start" menu → "Run", enter "cmd" to run the "Command Prompt", enter: "ipconfig/release" command and press Enter.

The function of this command is to release the dynamic IP addresses assigned by DHCP for all (or specified) adapters.

Then enter the "ipconfig/renew" command and press Enter. The function of this command is to reassign IP addresses to all (or specified) adapters.

In this way, the router will re-assign an empty IP address to your computer to avoid conflict with the IP addresses of other computers.

After running these two commands, the system can access the Internet normally.

八、假如別人用遠端控制我電腦上Q顯示的是我IP還是控制我電腦那人的IP?

答:因為qq是從你電腦上去的,所以別人是利用你的ip上去的,按道理來說,你是理論上的“肉雞”,他是在利用你的電腦來為他做位一個“掩體”,如果真的出什麼問題了,第一個找到的是你!等他離開你的電腦以後,把你電腦上的訪問日誌一清楚,就找不到他了!

這個就好比我們說的代理伺服器,只不過代理伺服器是把自己的網線搭建到別人的ip上,而你說的情況是他直接控制了你的機器,和用你的電腦上網是一樣的!有些記錄都會顯示在你電腦上的!

九、我電腦上的IP位址是唯一的嗎?

不是的。

比如說送快遞,快遞地址是:

xx省xx市xx路xx小區,4幢3單元1502室。

xx省xx市xx路xx小區,相當於公有 ip 位址。小區的地址是國家分配的,是唯一的。

4幢3單元1502室,相當於私有 ip 位址。物業給你分配的。你們社區有個6棟,我們社區也有個6棟,不是唯一的。

你看到的 ip 位址,就像小區裡的門牌號,不是唯一的。

十、如何改電腦的IP?

內網IP還是外網?

內網IP:

工作列右下角的網路圖示處點選右鍵,選擇[1]選擇進階網路設定 > 選擇變更適配器選項。在你目前連接的網路上點選右鍵,選擇「屬性」雙擊

外網 IP:

現在一般是動態 IP,重啟路由器就可以換外網 IP。
