# fping

**fping** is a network tool similar to `ping`, but designed for bulk pinging. It allows users to ping multiple IP addresses at once and reports which hosts are active or reachable. Unlike `ping`, which pings one host at a time, `fping` can ping a range of IPs efficiently.

```
fping -a -g [IP]/[CIDR]

-a: only show targets that are alive
-g: generate a list of IP to ping based on the specified subnet
-s: spoof the source IP address for pings

fping -a -g 192.168.1.0/24
fping -a -g 10.0.0.0/16 -s 192.168.1.100
```
