So, how to modify the mac address?

Two methods to modify the mac address

The mac address is assigned and burned by the manufacturer Into the network card chip, it is globally unique, and like a person's fingerprint, it can be used as important information for network card identification and host identification in underlying physical transmission. It is very simple to check the hardware address of the computer network card. Click "Start" and enter cmd and press Enter to run. Enter ipconfig /all on the command line and press Enter. In fact, the right side of the physical address corresponds to the special address of the network card, which is the MAC address.

If you want to modify the MAC address of the network card, you can actually do it without using tools, but the operation is quite complicated. The following uses the Vista system as an example to introduce how to modify the MAC address of the network card. Open the system desktop, use the right mouse button to select "Network and view "Properties". In the subsequent interface, click "Manage Network Connections" on the left, find the local connection that needs to be modified and select it again with the mouse. Select "" in the right-click menu Properties", click "Configuration" and go to the "Advanced" tab, select the "Network Address" column on the left, remove the unselected state on the right, select "Value" and enter the MAC address.

1. Simple modification method

Readers can right-click on the "Network Neighborhood" icon on the desktop, select "Properties", and in the pop-up "Network Connection" dialog box, Right-click on the "Local Area Connection" icon and select "Properties". A "Local Area Connection Properties" dialog box will pop up. Click the "Configure" button, select "Advanced", and select "Network Address" in "Properties" in the left column. "(In fact, not all network cards use "Network Address" to describe the physical address. For example, Intel's network card uses "Locally Administered Address" to describe it. As long as you can find the "Value" option in the right column ), and then select the above single option in the "Value" in the right column (not "Does not exist"). At this time, you can enter the MAC address of the network card you want to change in the box on the right, such as "000B6AF6F4F9" and click "OK" ” button, the modification is completed.

However, some network cards do not have this option. Don’t worry, you can try updating the driver of the network card first.

Then read on, the following method can be said to be omnipotent!

2. Registry modification method

Chapter Step 1, click "Start", select "Run", type "regedit" to bring up the registry.

Step 2, in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE -BFC1-08002BE10318}\0000, 0001, 0002 and other primary keys, search for DriverDesc. The content is the description of the network card to be modified. For example, Intel's network card will be described as "Intel (R) PRO/100 Management Adapter", 3Com's network card It will be described as "3Com EtherLink The location is related to the network card itself and the operating system. Different network cards may appear under different primary keys, and the same network card using different versions of the operating system (such as OEM version, VOL or VLK, etc.) will also appear in different locations. The task of this step is to find the primary key containing the network card description.

Step 3, select the primary key found in the second step, add a string in the right column, name it "Network Address", and set its value to the MAC address to be changed, in the form of "000B6AF6F4F9 ".
