Traceroute gives you a thorough view of the path between two devices and helps troubleshoot issues – but it takes a little time to complete. You will continue to find the ping command useful as well! But traceroute can be a great tool, particularly once you realize that two hosts cannot communicate. This video begins by describing the information traceroute can provide. Only then does it turn to the mechanisms traceroute uses to find that information, and it closes with some practical advice on using traceroute from routers.
