The MAC address is the physical address of a network interface. It is unique at the hardware manufacturer level and SCS Computing Facilities utilizes these hardware addresses to uniquely allow access to our network. Physical Address: Refers to the physical address of the Ethernet connection to your computer or server. MAC-48 was used to address hardware interfaces within existing 802-based networking applications; EUI-48 is now used for 802-based networking and is also used to identify other devices and software, for example Bluetooth. The IEEE now considers MAC-48 to be. MAC address - M edia A ccess C ontrol address. MAC addresses - hardware addresses that uniquely identifies each node of a network. It is assigned by the vendor or manufacturer and saved to the device memory. According to the OSI model it is a second-level address. Some wireless chipsets (Broadcom!!) use a software-defined MAC address that defaults to a value with the last 6 digits are all zeroes, and unless you override it, and if anyone else on your local network (at your school, office, etc) happens to have the same chipset in their device, your two devices will have the same MAC address and all sorts of evil can happen on that network. The MAC address that is hard-coded on a network interface controller (NIC) cannot be changed. However, many drivers allow the MAC address to be changed. Additionally, there are tools which can make an operating system believe that the NIC has the MAC address of a user's choosing. The process of masking a MAC address is known as MAC spoofing. Jul 03, 2017 These MAC addresses—sometimes referred to as physical or hardware addresses—are assigned in the factory, but you can usually change the addresses in software. What MAC Addresses Are Used For At the lowest networking level, network interfaces attached to a network use MAC addresses to communicate with one another.
A freeware utility to spoof MAC address instantly
Version 6.0.7

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
- Starting MAC address changer will list all available network adapters.
- Select the adapter you want to change the MAC address. You will get the details of your selection below.
- In the Information tab, find the Change MAC Address frame. Enter new MAC address in the field and click Change Now! button. You may even click Random MAC Address button to fill up a randomly selected MAC address from the vendor list available.
- To restore the original MAC address of the network adapter, select the adapter, click Restore Original button in the Change MAC Address frame.
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.
