Changing the MAC-address

Almost every computer user today is concurrently also Internet users.

Situations in life are different, and sometimes we need to know not only your ip address, subnet mask, gateway, and things like that, but this characteristic NIC as its MAC-address.



To begin with we define what is MAC-address. Roughly speaking, this is the ID number of the network card that allows you to clearly distinguish it from other cards similar architecture. However, it is worth remembering that not all network protocols used MAC-addressbut not everywhere need global uniqueness of theseaddresses. For example, the LAN address must be unique within the internet but may be an address and a poppy povtoritsya.Uznat possible through the use of console commands.


call method in each of the operating consoleyour system. For Windows Xp - a "Start" - "Run" - "the cmd", for Linux operating systems typically use a keyboard shortcut Ctrl + Alt + F1 or Ctrl + Alt + F2, etc. (Up to Ctrl + Alt + F6).


In order to find out the MAC-address of the network device, use the following commands:
Windows - ipconfig / all - in more detail paints - a MAC-address to which the network interface belongs.
For Linux is a command line you must fill the following code - ifconfig -a | grep HWaddr.


Mac OS X - ifconfig, or in System Settings & gt- Network & gt- choose to connect & gt- Extras & gt- Ethernet & gt- ID Ethernet.


It is believed that MAC-address tightly "sewn" into the network card schemes and changeits software in any way you can not. This statement is only partially true, because it holds only for systems with high requirements to the level of security, such as telecommunications.


In other cases, this address is easily changed by software. This is possible because the value specified by the driver, is more important than wired into the board.


To change the mac-address is in Windows, do the following.
Walk at the "Start" - "Control Panel" - "Network Connections" - select the desired connection - right-click - "Properties" - "Adjust" - "Advanced" tab.
In the Properties list, look for the parameter Network Address.
In the box "Value", enter the desired value.

When the address can be verified using the ipconfig / all command.


In Linux MAC-address changes with the following command as root:
# Ifconfig ethN hw ether
where ethN - network interface name.
