packet Internet groper (PING)

Packet Internet Groper (PING) is an implementation of the Echo protocol and is used to test the reachability of target stations on the Internet. For this purpose, a request is sent using the Internet Control Message Protocol (ICMP) and the response is waited for. The ping protocol checks whether a specific IP address

exists and can be reached. To check the reachability

, thetext

"Ping" is transmitted with the IP address of the target computer and then the response of the corresponding computer is waited for. Thetime span between sending the data packet to the target computer and back is called Round Trip Time (RTT) or ping time

.If the target computer does not answer, it is possible that it is not connected to the network or does not react to the ping. It may be configured to ignore all ICMP messages, of which ping is one. It will then not send back a ping. However, such a computer that does not respond to a ping signal can be connected to the Internet or to a local network

and work perfectly there. An alternative to the ping method is route determination using the traceroute method.
