fping
High performance ping tool
fping is a program to send ICMP echo probes to network hosts, similar to ping, but much better performing when pinging multiple hosts. fping has a very long history: Roland Schemers did publish a first version of it in 1992 and it has established itself since then as a standard tool for network diagnostics and statistics. There was no official fping release from 2002 until end of 2011.
