The command “nmap -sP 192.168.100.0/24” scans a network and identifies which hosts are alive (i.e., which IP addresses are being used) within the specified range.
In more detail, the “nmap” command is a widely used network exploration tool that can be used for tasks such as host discovery, port scanning, and service enumeration.
The “-sP” option tells nmap to perform a “ping scan,” where it sends an ICMP echo request to each host in the specified IP range and checks for responses. This method is typically faster than other scanning techniques because it only determines whether a host is up or not without gathering additional information about the host’s ports or services.
The “192.168.100.0/24” argument specifies the IP range to be scanned, specifically the subnet mask “255.255.255.0,” which corresponds to the range of IP addresses from 192.168.100.0 to 192.168.100.255. The “/24” suffix is a shorthand notation for the subnet mask.
Overall, the command “nmap -sP 192.168.100.0/24” is a helpful tool for network administrators or security professionals who need to identify which hosts are active on a particular network quickly. It can help to identify potential security vulnerabilities or unauthorized devices connected to the network.
