-Pn (No ping) . This option skips the Nmap discovery stage altogether. Normally, Nmap uses this stage to determine active machines for heavier scanning. By default, Nmap only performs heavy probing such as port scans, version detection, or OS detection against hosts that are found to be up.

What is CIDR notation?

CIDR notation (Classless Inter-Domain Routing) is an alternate method of representing a subnet mask. It is simply a count of the number of network bits (bits that are set to 1) in the subnet mask. The CIDR number is typically preceded by a slash “/” and follows the IP address. For example, an IP address of 131.10.

How to scan the whole range of an octet with Nmap?

Note: if you want nmap to scan the whole range of an octet you can replace 1-255 for wildcard (*). The parameter -sL (List scan) is the less offensive one, it enumerates the IP addresses in the network and tries to resolve through reverse-DNS lookup (resolve from ip to host) to know the hosts are there.

How do I scan more than one IP address in nmap?

If the name resolves to more than one IP address, only the first one will be scanned. To make Nmap scan all the resolved addresses instead of only the first one, use the –resolve-all option. Sometimes you wish to scan a whole network of adjacent hosts. For this, Nmap supports CIDR-style addressing.
