Mac Address Spoofing / Changing

The MAC address (Media Access Control address or addresses of media access control) is basically a unique hexadecimal identifier that possess most of the equipment associated with networks.

An Ethernet MAC address is a six byte number, usually expressed as a twelve digit hexadecimal number (Example: 1AB4C234AB1F).ddress (Media Access Control address or addresses of media access control) is basically a unique hexadecimal identifier that possess most of the equipment associate

Changing Your MAC Address Or Mac Address spoofing :- 

Step 1.

The MAC Address in principle were designed so they can not be changed. However, there are many reasons (legal or not) to justify the fact that you want to change your MAC Address. One of these reasons, and perhaps the main one, is that ISPs, Cable Modem, more precisely, record and monitor your users by MAC Address, which often create certain disadvantages (e.g to share the Internet connection with other PCs).

Step 2.

There are several ways to modify and / or clone the MAC Address on Windows, including complex changes in the registry (regedit.exe), but the easiest one I found was to use a small application called EtherChange (runs on Windows 2000/XP/2003 / Vista).EtherChange After downloading, run the program and proceed to change or modify the MAC Address, If you are not able to run the program directly then another way to copy the program (etherchange) to drive in which operating system is installed. 

Example:- I copied Etherchange to C drive as window is installed in C, Now location of the etherchange is C:\etherchange ,Now go to Start-->Run-->cmd, Then in cmd(Command Prompt) go to path as C:\etherchange and enter ,then follow step 3 

Step 3.

Select the appropriate network adapter (network card). 
type 1 to specify a new ethernet address, or MAC Address. 
Enter new MAC Address without commas, dashes or any other separators. 

Clever! Now just restart your computer to enable the new MAC Address.
