fping - send ICMP ECHO_REQUEST packets to network hosts

NAME
fping - send ICMP ECHO_REQUEST packets to network hosts

SYNOPSIS
fping [ options ] [ systems... ] fping6 [ options ] [ systems... ]

DESCRIPTION
fping is a program like ping which uses the Internet Control Message Protocol (ICMP) echo request to determine if a target host is responding. fping differs from ping in that you can
specify any number of targets on the command line, or specify a file containing the lists of targets to ping. Instead of sending to one target until it times out or replies, fping will send
out a ping packet and move on to the next target in a round-robin fashion. In the default mode, if a target replies, it is noted and removed from the list of targets to check; if a target
does not respond within a certain time limit and/or retry limit it is designated as unreachable. fping also supports sending a specified number of pings to a target, or looping indefinitely
(as in ping ). Unlike ping, fping is meant to be used in scripts, so its output is designed to be easy to parse.

The binary named fping6 is the same as fping, except that it uses IPv6 addresses instead of IPv4.
