Ubuntu – the active MAC Address of the computer

12.10ethernetifconfignetworkingwireless

While looking to find the MAC Address of my computer as it appears to a wireless network, it was recommended that I run ifconfig.

Having executed that command in the Terminal, I noticed that, unlike my other machine, the connected network seemed to be listed as an Ethernet, even though the built in wireless card is the thing I am currently using to post this.

ifconfig output:

Is it possible that Ubuntu is confused somehow?

If not, am I misinterpreting my results, and my MAC Address may not be 00:0c:f1:53:55:c5 ?

I am not exactly sure why this happens, but I have seen it before too.

You are right about the MAC address -- it's the one in eth1.
