fping is a ping like program which uses the Internet Control Message Protocol (ICMP) echo request to determine if a host is up. fping is different from ping in that you can specify any number of hosts on the command line, or specify a file containing the lists of hosts to ping.

Instead of trying one host until it timeouts or replies, fping will send out a ping packet and move on to the next host in a round-robin fashion.

If a host replies, it is noted and removed from the list of hosts to check. If a host does not respond within a certain time limit and/or retry limit it will be considered unreachable.

Unlike ping, fping is meant to be used in scripts and its output is easy to parse.

Problem and Issues:

With a large a number of IP addresses in use, its becomes more and more time consuming to check on which IP addresses are actively in use, and which critical machines (routers, bridges, servers, etc) are reachable. One example is we have a program which goes through all of our routers arp caches looking for IP addresses that are in use. After finding a list of IP addresses that aren't in any arp caches fping can then be used to see if these IP addresses really aren't being used, or are just behind the routers. Checking 2500 hosts (99% of which are unreachable) via ping can take hours.

fping was written to solve the problem of pinging N number of hosts in an efficient manner. By sending out pings in a round-robin fashion and checking on responses as they come in at random, a large number of hosts can be checked at once.
