It is used to verify end to end connectivity. Also helps to verify that the network is configured correctly, if you can get the reply, sometimes a reply may not come even if the if packets can reach the other end. That can be confirmed with a trace route. If the other end is reachable you get a reply, if it is out of reach you get a destination host unreachable, and if you can reach it but cannot get a reply you get a timeout.
