what is my MAC address, how do i find the MAC address of my computer
In computer networking, a Media Access Control address (MAC address), Ethernet Hardware Address (EHA), hardware address, adapter address or physical address is a quasi-unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for identification. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number.
On Linux systems, the ethernet device is typically called eth0
. In order to find the MAC address of the ethernet device, you must first become root, through the use of
. Then, type
and look up the relevant info. For example:
# ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:60:08:C4:99:AA
inet addr:220.127.116.11 Bcast:18.104.22.168 Mask:255.255.248.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:15647904 errors:0 dropped:0 overruns:0
TX packets:69559 errors:0 dropped:0 overruns:0
Interrupt:10 Base address:0x300
The MAC address is the HWaddr listed on the first line. In the case of this machine, it is 00:60:08:C4:99:AA.
If you have TCP/IP installed, run ipconfig/all
from a Command Prompt window.
(click Start, then Run, then type cmd in the text
Type in ipconfig/all in the Command Prompt Windows.
The 12-digit Physical Address is the same as MAC address
*You will need to register all MAC addresses in cases where you have both
wired and wireless interface in your system.
On a FreeBSD machine the command dmesg
will display the MAC address, among other things.
