How to modify a physical IP address (MAC address)

Method 1: Right-click the "Network Neighbor" icon on the desktop and select "properties". In the displayed "network connection" dialog box, right-click the "local connection" icon and select "properties". A "Local Connection Properties" dialog box is displayed. Click "Configure" and select "advanced ", select "network address" in the "attribute" column on the left (in fact, not all NICs use "network address" for the physical address description ", for example, Intel's network adapter uses "locally administered address" to describe, as long as the "value" option can be found in the right box ), then, select the single option (not "nonexistent") in the "value" in the right column, and enter the MAC address of the NIC in the box on the right, format: 000b6af6f4f9, set the physical address of the local machine to the address queried, OK ). Click "OK" to complete the modification. Note: restart your computer and the settings take effect.

However, some NICs do not have this option. Do not worry. You can update the NIC Driver first.ProgramTry it. This option will usually appear after the driver is updated. But there are still some special cases. No matter how you modify it, there is no such option. What should we do? Next, let's look at the following method as omnipotent!

Step 2 of the second method for registry modification, click Start, select Run, and type regedit to bring up the registry. Step 2: Find driverdesc in the primary key of HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ class {4d36e972-e325-11ce-bfc1-08002be10318} 000, 2nd, 0001, and 0002. The content is the description of the NIC to be modified, if an Intel Nic is described as "Intel (r) Pro/100 + management adapter ", 3Com NICs are described as "3Com etherlink XL 10/100 PCI for complete PC management NIC (3c905c-tx. Note: The locations of the NIC description options mentioned above are related to the NIC itself and the operating system. Different NICs may appear in different primary keys, and the same Nic may use different versions of the operating system (such as OEM, vol, or vlk) in different locations. The task in this step is to find the primary key that contains the NIC description. Step 2: select the primary key found in step 2, add a string in the right column, and name it "network address". The value is set to the MAC address to be changed, the format is "000b6af6f4f9 ". Note: In this step, the task of modifying the physical address of the NIC can be said to be completed. Some NICs need to restart the following to work normally, and some just need a little time to "respond. The following steps are convenient for you to modify the physical address in the future. If you do not need to modify the address again, you can stop here. Step 2: Add a primary key named "networkaddress" under "primary key selected in step 1" ndiparams. Generally, a "(default)" string is generated in the right box, set the value to the MAC address to be modified, for example, "000b6af6f4f9 ". If you do not have this string, you can add it yourself. Note: This step sets an initial MAC address for the NIC. Step 2: Add a string named "paramdesc" under the primary key of "networkaddress". The function is to specify the description of the primary key of "networkaddress". The value can be named by yourself, for example, "network address". In this way, the "Network Address" option appears in the Advanced properties of the network adapter, that is, the new "networkaddress" item just added in the registry ", you only need to modify the MAC address here. Step 2: Add a string named "optional" under the primary key of "networkaddress" and set its value to "1 ", if you select "network address" in the Advanced properties of the network adapter, the "nonexistent" option will appear on the right. Step 2: restart the computer (not necessarily restart, but depending on the requirements of different NICs. However, there is no error in restarting .), Find the "advanced" option in the first method and you will find that the "Network Address" option already exists in the "attribute" column. Now, the reader can directly modify the MAC address or restore the original address. The above two modification methods ensure that the reader can modify the physical address of any Nic. I hope the author's summary and experience can help you.
