Method 1 of 3: Fake MAC Address on Windows
Step 1. Open the Start menu
Look at the bottom right corner of your screen, and find the Start icon. This icon looks like a round, colorful window.
Step 2. Click Control Panel
Once you have opened the Start menu, look at the right side of this menu, then click Control Panel..
Step 3. Click on Network and Internet
After opening the Control Panel, you will be presented with various options. Click Network and Internet.
Step 4. Click on Network and Sharing Center
From within the Network and Internet category, look for the Network and Sharing Center option. This option is probably the first option you'll see in a new window. When you find it, click it.
Step 5. Click Change Adapter Settings
Once in the Network and Sharing Center window, you can view your computer's network/communication settings and connections. Look at the left side of the window, and select Change Adapter Settings.
Step 6. Select Local Area Connection
In this window, you will be presented with various network connections. Select Local Area Connection.
Step 7. Click Properties
From the Local Area Connection window, click Properties. Then, click Configure.

In the Configure window, look at the top right corner of the window and look for the Advanced option. Click Advanced.
Step 9. Click on Locally Administered Address
In the Advanced tab, there will be a smaller window, titled Settings. Scroll down until you find Locally Administered Address and click this option.
Step 10. Look at the bottom of the newly opened window
After you click Locally Administered Address, there will be text on a yellow background. The text will say something like this: "Change the MAC Address used by the network adapter". With this option, you can change your MAC address.
Step 11. Look for the Value option to fake your MAC address
Right next to the Settings window, there will be a box under Value where you will enter the character combination that will make up your new MAC address. Before entering a new combination, you need to look at the current combination.
Step 12. Type "cmd" (without the quotes) in the Start menu search box
Move the cursor to the Start button, then click that button. At the bottom, there is a search box, under All Programs. Type "cmd" (without the quotes), then look at the top. In that section, the search results will be listed, and one of them is cmd.exe. Click this file.
A new black window will appear
Step 13. Type "Getmac" (without the quotes)
In the CMD window, there will be a blinking _ sign. That's where you'll type. Type "getmac" (without the quotes), then press Enter.
A list of physical addresses will appear. The first address is your current MAC address
Step 14. Return to the Advanced window
Now, you can change your current MAC address by following your old address format (12 characters in total), and changing numbers and letters. You can use any combination of letters from A to F and any number. Under Value, enter your new address.
For example, if the first 4 characters in your MAC address are F1-D2, you can change them to F4-D1. Perform the same action for the remaining characters. Change the combination while keeping the arrangement
Step 15. Click OK
Once you have entered the new address of your choice, click OK at the bottom of the window. The Advanced window will disappear and you will see movement in Local Area Connections, under the Network Connections tab.
- Initially, there will be an X next to Local Area Connection and it says Disabled or Unplugged. This means your computer is making changes.
- After a few seconds, the X will disappear and the Local Area Connection will be Enabled again. You have changed your MAC address.

Once you have opened Terminal, click on the new window that appears, then type the following command: "sudo ifconfig en0 ether xx:xx:xx:xx:xx:xx" (without the quotes). Those 12 X's need to be replaced with your new MAC address value. You can make any combination you like, with the letters A to F and any number. Follow the order below with your own combinations.
- Example command: "sudo ifconfig en0 ether d4:33:a3:ed:f2:12" (without quotes).

Method 3 of 3: Fake MAC Address on Linux with Macchanger
Step 1. Open a Terminal window
Look at the top-left corner of your screen, then click the square icon that marks the Terminal option.
Step 2. Enter the "Macchanger" command
Once you have opened Terminal, type "Macchanger" (without the quotes) in the space provided. You may have to enter it twice. When you have entered the command and the system says "Try Macchanger", type the same command again and then press the "Return" key on your keyboard.
- There will be several commands that appear with the corresponding code.
- At the bottom there will be characters marked as MAC addresses.
Step 3. Type the command "macchanger eth0 -r" (without the quotes)
Then, press the "Return" button on your keyboard. The system will generate three addresses. The first two addresses will be marked "Permanent" as well as "Current MAC Address". The last MAC address will be marked "New".
- You can use the newly created MAC address; if so, you don't have to do anything else.
- To use a MAC address of your own choice, follow these steps.
Step 4. Type the command "macchanger eth0 -m" (without the quotes)
Then, select your new numeric address configuration. Make sure your new address is 17 characters long including the colon. Make sure you follow the order like this: XX:XX:XX:XX:XX:XX. Replace these X signs with any combination of numbers and letters A to F. For example, 56:95:ac:ee:6e:77.
The full command would look like this: "macchanger eth0 -m 56:95:ac:ee:6e:77" (without the quotes)
Step 5. Press "Return"
Your new MAC address is now set. You can see it under the "New" sign.
- If the macchanger steps above don't work for you, you may need to turn off your interface. To do this, open a terminal window and enter the following command: "ifconfig eth0 down" (without the quotes).
- Now, try again.
