Study notes: MAC Spoofing
Study notes are my personal research notes on certain topics that interests me.
Any network capable device has a unique factory-assigned Media Access Control (MAC) address. Users have no way to change the MAC address but it can be done. However, it is possible to mask the MAC address and have it show a different value. This is called MAC spoofing.
There are legitimate uses for MAC spoofing. For example, there may be certain applications that require a particular MAC address to work, or maybe your ISP expects a certain MAC address to connect to the network. MAC spoofing is largely used for illegitimate uses, like circumventing an access control list or getting past a filter on a wireless network.

To view the current MAC address:
$ ifconfig
