Re: Ping a mac address

That's why I was asking "why?"  It depends on what he's ultimately going to 
do and what the host is...  All packets are not automatically dropped if the 
IP doesn't match the bound IP -- that's what the MAC is for in the first 
place.  For instance, I have a few IP cameras around my infrastructure... If 
I add a static ARP entry for the MAC to some arbitrary IP (that's still on 
my subnet) I can use that arbitrary IP to access the unit's HTTP 
configuration... works just fine.

Maybe I misunderstand your point, but as you will be indeed be able to
send that host an ethernet frame knowing its MAC address, you may want
to have it processed at upper layers, if you need to coomunicate with
that host for instance. As it will drop any packet that is not destined
to its very own IP address (or one of its, if multiple), you definitly
need to know it for this kind of purpose.
