Technitium MAC Address Changer allows you to change (spoof) Media Access Control (MAC) Address of your Network Interface Card (NIC) instantly. It has a very simple user interface and provides ample information regarding each NIC in the machine. Every NIC has a MAC address hard coded in its circuit by the manufacturer. This hard coded MAC address is used by windows drivers to access Ethernet Network (LAN). This tool can set a new MAC address to your NIC, bypassing the original hard coded MAC address. Technitium MAC Address Changer is a must tool in every security professionals tool box.

How Does It Work?
This software just writes a value into the windows registry. When the Network Adapter Device is enabled, windows searches for the registry value 'NetworkAddress' in the key HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlClass{4D36E972-E325-11CE-BFC1- 08002bE10318}[ID of NIC e.g. 0001]. If a value is present, windows will use it as MAC address, if not, windows will use the hard coded manufacturer provided MAC address. Some Network Adapter drivers have this facility built-in. It can be found in the Advance settings tab in the Network Adapter's Device properties in Windows Device Manager.
How To Change MAC Address
NOTE: This tool cannot change MAC address of Microsoft Network Bridge. Network Bridge will automatically use the original MAC address of the first NIC added into bridge with the first octet of MAC address set to 0x02.

For a manufacturer search using a MAC address, at least the first 3 bytes (6 characters) of your MAC address are required. If even the smallest address ranges assigned by the IEEE are to be searched, the first 5 bytes (20 characters) of your MAC address are required. You can enter your MAC address with or without separators (
-or :). Mac Address Vendor Part
You can also search for the name of a manufacturer (at least 3 characters) and get a list of the MAC ranges assigned to the manufacturer. To search for a manufacturer, it is also possible to enter a part of the manufacturer name.
How do I find my MAC address?
The easiest way to get your Mac address under Microsoft Windows is to open the command line or Powershell and enter the command: ipconfig /all. The now displayed
Physical Addressis the MAC address of your network device. Alternatively, you can enter the name of a manufacturer in the search and receive a list of MAC ranges assigned to the manufacturer.
Under Linux or macOS open a console/terminal window and enter (Linux) 'ip link' or (MacOS) 'ifconfig /all' there. Here you will find your MAC address under 'link/ether“,
HWaddror Hardware Address. What is the MAC address and where does the data come from?Mac Address Vendor Database
The MAC address is a 24 bit (12 characters) long identifier of network devices, which is also called Organizationally Unique Identifier (OUI) or MA-L. This identifier is assigned by the IEEE to manufacturers of network devices. This identifier forms the first 3 bytes (6 characters) of the MAC address for the manufacturer's network devices.
Since 01.01.2014 it is possible for manufacturers who have a lower need for MAC addresses to register a smaller/cheaper block with MAC addresses. For this a MA-M block (for 4096 MAC addresses) or MA-S block (256 MAC addresses) is available. Before 01.01.2014, an Individual Address Block (IAB) was available for this purpose, whereby this database is no longer maintained by the IEEE.
In addition to the MAC addresses for network devices, it is also possible to reserve a MAC block for applications that do not require a globally unique MAC identifier. Some smartphones use these MAC areas to disguise the owner while searching for a known Wifi network. These MAC ranges are listed under the name Company ID (CID).
Further details on the individual vendor databases can be found on the IEEE FAQ page.
