Hardware address cannot be changed as we all know that it
is 48 bit in size and it is a world wide unique address
which is having 2 parts 24 is OUI and 24 bits is vendor
assign OUI is to identify the vendor of the card.
So conclusion - It cannot be changed in any scenario.

Answer / ramesh rao

Your MAC address is your future security....

In IPv6 the MAC address plays a major role...
the 48 bit address will be added with FFFE
Example: 3B-A7-94-FF-FE-07-CB-D0

This makes it 64 bit address and the remaining 64 bit
specific to Country, ISP, Company etc..

Since the MAC address is unique and the becoming end points
for communication between hosts, the security is achieved
and as such there is no broadcast as in IPv4

Answer / anirban

Answer / narayana

mac address is nothing but a physical address of the system

it cannot change because it is unique

Answer / a

MAC - Media Access Control
- Also known as physical address (cannot be changed
convetionally)
- (IP Address - logical address - can be changed)
- contains 48 bits or 6 bytes
- Example 00-13-02-C0-14-13
FF-FF-FF-FF-FF-FF - ARP broadcast
Each F (in this case) is an Hexa decimal number is
called "Nibble"
The first 3 bytes (00-13-02) is vendor specific
The second 3 bytes (C0-14-13) - is allocated to the
vendor by the IEEE
- MAC address can be used for security (in Switches)
- MAC address security is extra protection in Wireless
Networks
- MAC spoofing (changing the MAC address) can be used
or both for good and bad purposes (Not recommended -
may create issues in your network)
- Use "ipconfig /all" or "net config rdr" in command
prompt
- to change MAC (NIC properties / advanced TAB /
Locally administered Address / in XP / VISTA)

Answer / amol lodha

It is not possible to change the MAC address of a system.
It is unique 64bit(6 Byte) address given by manufacture.
