In computing, a ping sweep is a method that can establish a range of IP addresses which map to live hosts.
The classic tool used for ping sweeps is fping,[1][2][3] which traditionally was accompanied by gping to generate the list of hosts for large subnets,[4] although more recent versions of fping include that functionality.
[1] Well-known tools with ping sweep capability include nmap for Unix and Windows systems, and the Pinger software from Rhino9 for Windows NT.
[4][5] There are many other tools with this capability, including:[2][5] Hping, IEA's aping, Simple Nomad's ICMPEnum, SolarWind's Ping Sweep, and Foundstone's SuperScan.
There is also a ping sweep tool for Windows, Mac, Linux, Android, and iOS called Fing made by Overlook Soft.
