Input targets from file
nmap -iL
Choose random targets
nmap -iR
Specify ports to scan
nmap -p
For example, NMAP -sT -p 1-1024 10.0.0.0 /8 will scan the whole 10 network for ports 1 through 1024.
Scan fewer ports than default (fast mode)
nmap -F
Scan from a script
nmap –script
Scan with IPv6
nmap -6
Configure timing of scan (higher num is faster)
nmap -T<0-5>
Controls timing template
You can slow your scans down to try to avoid detection by the IDS
