Fping
Examples

Notes
Ubuntu: sudo apt-get install fping
openSUSE: sudo zypper install fping
Windows: http://fping.sourceforge.net/
Examples:
In its most simple form, you can use fping just like ping:
fping 172.31.0.251
You can do a network scan that sends one ping packet per/IP:
fping -a -r 0 -g 172.31.0.0/24
Or 4 ping packets per/IP (the "-r" is for retry):
fping -a -r 3 -g 172.31.0.0/24
You can do an even faster network scan by by adding "-i 1" switch (Requires sudo, waits 1ms between pings):
sudo fping -a -i 1 -r 0 -g 172.31.0.0/24
You can do the same fast scan, but from a host-list like this:
sudo fping -a -i 1 -r 0 < host_list.txt
You can add "-s" to any scan to show cumulative statistics upon exit:
fping -s -a -r 0 -g 172.31.0.0/24
