[vox-tech] different MAC address when using "ifconfig" and "arp"

[Hai Yi]

Hello,

I thought I can get my ether card's MAC address by using either
"ifconfig eth0" command or "arp -v" command, but these commands
returned different MAC address(00:16:E6:5C:DA:B8 vs
00:14:BF:D3:AE:29). Did I miss something here?

I am using Ubuntu and the following are the results:


hai at zodiac:~$ ifconfig eth0
