In the case of the school network network, the host always binds the single-machine network card MAC address in the subnet, so if you want to change the network card or change the machine, you can use the same IP, you have to Go to the management personnel to help you modify the binding.
Now it is good, use the following method to solve this unnecessary trouble.
Simple thinking: First, write down your own NIC's MAC address, which is the MAC address that is bound, then modify the new network card or another network card (or another PC network card) MAC address to this address. I.e. (Of course, this can also be used for the stolen use of IP addresses, huh, this statement: this is purely research technology, please don't maliciously malicious IP)
