fping:tldr:fd192

The command "fping -a -g 192.168.1.0/24" is used to send ICMP echo request packets to a range of IP addresses in order to check their availability or measure their round-trip time. Let's break down the command:

• "fping" is the name of the command-line tool being used. It stands for "fast ping" which allows sending multiple ICMP echo requests in parallel.
• "-a" is an option that tells fping to only display the IP addresses that are alive or responding to the echo requests. This filters out any non-responsive hosts from the output.
• "-g 192.168.1.0/24" is another option that provides the IP address range to scan. Here, "192.168.1.0/24" represents the subnet in CIDR notation. The "/24" indicates that the range includes all IP addresses from 192.168.1.0 to 192.168.1.255.

So, when you run the command "fping -a -g 192.168.1.0/24", fping will send ICMP echo requests to all IP addresses in the 192.168.1.0/24 subnet and display only the IP addresses that respond.
