Before we scan the live targets, we need to specify them. Generally, we provide a list, a range, or a subnet. Examples of target specification are:
- list:Â
10.11.12.15 scanme.nmap.org example.com - will scan 3 IP addresses. - range:
10.11.12.15-20Â - 6 IP addressesnmap -sL -n 10.10.0-255.101-125- 6400 IPs lol
- subnet:Â
10.11.12.15/30Â - 4 IP addresses - list of targets:Â
nmap -iL list_of_hosts.txt- as many as in the list
nmap -sL list_of_hosts.txt will give a detailed lists of hosts to scan without actually scanning them with reverse-DNS resolution on all targets to obtain their names (unless blocked with -n).
