Hi ranjeet, first of all Welcome to WebmasterWorld!

We have a similar thread [webmasterworld.com] currently running about blocking traffic from a specific US state. Although that is slightly different looking at the size of the IP range which has to be blocked, the available solutions are the same. I would therefore like to invite you to join that thread.
