I need to scan large network which has 5000 IPs. I have limited time duration. I have done initial maths and concluded that, in a group of 4 individual has to perform 70 IP nmap scan.
Consider that I want more out of nmap. Which method will be effective for me?
Initially I thought of running top 1000 ports scan and then to perform all 65535 port scan in the range where I got some results after performing initial 1000 ports scan. Assume that rest all hosts are dead in which I have not got the result. Also I want to check those even roughly.
What would you recommend? Which scan type and methodology shall I follow to achieve my target?
