Answer by Ramesh - Cisco Instructor
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)
