![]() ![]() In contrast to a single ping, a ping sweep uses ICMP (Internet Control Message Protocol) ECHO requests to communicate with multiple hosts at the same time. Ping sweep, also known as ICMP sweep or a ping scan, is a network scanning technique you can use to find out which IP addresses map to live hosts. If a ping fails altogether, you can ping surrounding parts of the network to see if the issue is isolated or widespread. For example, if a ping is successful by name and IP address but the device takes a long time to respond, you now know there might be a network speed or congestion issue.
