fping

sends ICMP ECHO_REQUEST packets to network hosts
fping is a ping like program 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.
