Since I've never used it, I cannot tell you much more about it.
For the average user or network administrator, I doubt very much they will ever need to use fastping as the nature of the "ping" utility is to enable us to test network connectivity through simply or complex networks and also calculate round trip times of packets traveling in some direction.
Furthermore, you might be interested in knowing that the 'ping' utility is an implementation of the ICMP (Internet Control Message Protocol) protocol. You can find more information on ICMP and all its various uses at http://www.Firewall.cx
