MAC address modification recovery

Step 1, calculate the MAC address.

When all computers are turned on, count the IP addresses obtained now. When copying, write down two things, the computer number and the last digit of the IP address. After the inventory is completed, use a LAN scanning software to scan all the machines in the network segment, then run cmd, and then use ARP-A command to obtain the current IP addresses and MAC addresses of all computers.

The second step is planning.

Make a five-column excel table, first paste the IP address and MAC address obtained by ARP-A command. When copying in the cmd command window, remember to copy the IP and paste it into one column, then copy the MAC address and paste it into another column. Don't copy IP and MAC together, so that the pasted IP and MAC are in one cell, and then enter the computer name planned by this computer.

? The third step is batch processing.

? Finish this form and make a batch directly. The code is as follows:
