Re: Preventing IP conflict
After reading the suggestions from people around i was not able to
understand what it has to do with DHCP. in case if your machine runs
as DHCP client you will get another IP address as soon as you reboot
the machine or any other IP which is not being used from within the
network.

Another thing i am not able to stand is what your DNS server
malfunctioning has to do with your machine's ip conflict.. DNS just
does the work of resolving name to ip and ip to names.

i would suggest to check /var/log/messages. anytime you get any kind
of problem with the network or anything the system logs it in
/var/log/messages which can help you identify the problem. in case of
problems od DUP IP. it clearly thoroiws a message of dup present in
the network with the Mac address of the network card which is using
it.
Furthermore, a lot of implementaion of tools are being done on the
newer linux ditros which can actually warn you about existence of DUPs
in network. the moment they come up in network.. the same way it
happen in MS Windows.
