Pinging Multiple Hosts
fping shines when pinging multiple hosts. You can specify multiple IP addresses or hostnames separated by spaces:

Pinging from a File
If you have a large list of hosts, you can store them in a text file (e.g., hosts.txt) and ping them using:
fping -f hosts.txt
Output Options
fping provides several output options. You can display the results in a more readable format by using the -a option to show only alive hosts:
fping -a -f hosts.txt
To show more detailed output, use the -v option for verbose mode:
fping -v example.com
Useful Options
-g: Generate a list of IP addresses in a given range. For example:
fping -g 192.168.1.1 192.168.1.255
-t: Set the timeout for each ping in milliseconds. For example, to set a timeout of 100ms:
fping -t 100 example.com
-r: Set the number of retries for each host. For example, to retry 3 times:
fping -r 3 example.com
