ping IP subnet block howto

Here's a quick way on how to send ICMP echo request to a group of host to determine if they are responding or unreachable.

There are only a few advantage of using fping instead of ping linux command. One is you don't need to create a shell script that pings list of IP address from a batch files. With fping, you can try to ping a group of consecutive IP address in just a single command. Another benefit from using fping is it jumps on sending the next ICMP echo request to a host on a round-robin fashion, just like calling ping while feeding it with another IP address.

Like so:

# fping -g

# fping -g

which sends ICMP echo requests to the full block of CLASS C IP address from to

You might want to try

# fping -g
