Yes perhaps it's a language problem :)
I mean real alias when I can create an "interface" with a specified MAC 
address and a specified IP address attached to a physical device. Actually I 
can create IP alias (with ifconfig alias for example) but I can't create a 
MAC address alias associed with this IP alias.
Am I wrong ?
