Subject: broadcast arp messages and linux kernel

Hello,
Recently I have detected an IP conflict while my OS is redhat.
 Searching for a solution revealed that linux kernel doesn't reply to 
broadcast arp messages *at all*. As a result when someone asks "who has 
ip A.B.C.D?", my kernel won't reply to that and the other host thinks no
 one has that IP so there will be a conflict.

I also searched a lot to find why kernel won't reply to that but didn't find a clear answer.
Don't you think kernel should reply to those messages?

Regards,
Mahmood
