Linux / UNIX: Ping a Block of Hosts (netblock)

You can use the fping command to ping a block of hosts or a netblock. The fping command is similar to the ping command but it allows you to specify a range of IP addresses or a network range to ping multiple hosts at once.

To ping a block of hosts, you can use the following command:

In this example, the -g option is used to specify a network range to ping. The 192.168.1.0/24 specifies the range of IP addresses to ping. The /24 is the CIDR notation for the subnet mask, which means to ping all IP addresses in the range of 192.168.1.1 to 192.168.1.254.

If you want to save the output to a file, you can use the redirection operator > to save the output to a file:

This will save the output of the fping command to a file called ping_results.txt.
