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.

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！

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。
