Hi Pavan, I don't think Cloudera Manager assign the address to your computer. When CM is down, your computer still have an IP, and even if you un-install CM, you will still have an IP assigned to your computer.
If you have not configured anything there, then you most probably have a DHCP. Just give a try to what I told you on the other message.
