Ping sweep

Ping sweep

A Ping sweep is a technique used to determine which of a range of IP addresses map to live hosts. It consists of ICMP ECHO requests sent to multiple hosts. If a given address is live, it will return an ICMP ECHO reply.

A ping is often used to check that a network device is functioning. To disable ping sweeps on a network, administrators can block ICMP ECHO requests from outside sources. However, ICMP TIMESTAMP and Address Mask Requests can be used in a similar manner.

Tools used for ping sweeps include fping, gping, and nmap for Unix systems, and the Pinger software from Rhino9. Pingers send multiple packets at the same time and allow the user to resolve host names and save output to a file.
