fping 5.5

FPing is a ping-like program that 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 a list of
targets to ping. Instead of sending pings to one target until it times
out or replies, FPing sends a ping packet and moves on to the next
target in a round-robin fashion.
