List targets only nmap 192.168.1.1/24 -sn Disable port scanning nmap 192.168.1.1-5 -Pn Disable host discovery. Port scan only nmap 192.168.1.1-5 -PS22-25,80 TCP SYN discovery on port x. Port 80 by default nmap 192.168.1.1-5 -PA22-25,80 TCP ACK discovery on port x. Port 80 by default nmap 192.168.1.1-5 -PU53 UDP discovery on port x. Port 40125 by default nmap 192.168.1.1-1/24 -PR ARP discovery on local network nmap 192.168.1.1 -n Never do DNS resolution Port Specification Switch Example Description -p nmap 192.168.1.1 -p 21 Port scan for port x -p nmap 192.168.1.1 -p 21-100 Port range -p nmap 192.168.1.1 -p U:53,T:21-25,80 Port scan multiple TCP and UDP ports -p- nmap 192.168.1.1 -p- Port scan all ports -p nmap 192.168.1.1 -p http,https Port scan from service name -F nmap 192.168.1.1 -F Fast port scan (100 ports) --top-ports nmap 192.168.1.1 --top-ports 2000 Port scan the top x ports -p-65535 nmap 192.168.1.1 -p-65535 Leaving off initial port in range makes the scan start at port 1 -p0- nmap 192.168.1.1 -p0- Leaving off end port in range makes the scan go through to port 65535
