Ping sweep

Ping sweep

(also ICMP sweep, ping scan)

Ping sweep definition

A ping sweep is a network scanning method or technique that has the ability to determine which IP addresses from an IP address range should live on hosts. The hosts are usually computers. A ping sweep can communicate with multiple hosts simultaneously by using ICMP (Internet Control Message Protocol) ECHO requests, commonly known as “ping.” For example, you can use a ping sweep to identify the total number of hosts you have on your network. All you’ll need to do so is your network ID – IP address. However, you should be aware of ping spoofing – sending false pings. This is used to send false information, and it can make your routers and firewalls inoperable.
