The PING command uses the services of the Internet Control Message Protocol (ICMP), the latter being encapsulated in the IP header. Therefore, the ping utility operates basically on layer 3 (the Network layer) of the OSI model. It does not use the services of the Transport layer, and the reason for that is that traffic reliability issues are not the case here. Ping performs a simple host lookup. TRACEROUTE  is another very helpful utility that operates similarly to ping and also uses the services of the ICMP protocol. Traceroute, as the name implies, is used to trace the path between the sender and the destination host. It is a one-way trace, meaning that it traces the route from the source to destination and not the other way around, which by the way, may follow a different path. Traceroute also uses the services of User Datagram Protocol (UDP), in specific implementations, as the transport layer for a specific reason that we'll go into further on. In order to understand

Hope you guys are aware about PING. If don’t know worries I will explain to you with easiest technical definition. A ping is a signal sent to a particular  host  that requests a response. It serves below two main purposes: 1) To check if the host is available and 2) To measure how long the response takes. A ping request can be performed using a  ping  command, which is a standard command in most  command line interfaces . Several  network  utilities provide a ping feature, which allows you to ping a  server  by simply entering the  IP address  or  domain name . Most ping programs send multiple pings and provide and average of the pings at the end.   Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol network. It is available for virtually all operating systems that have networking capability, including most embedded network administration software. PING In terms of te
