Introduction The “traceroute” command is a network diagnostic tool that allows users to track the route that a packet takes from the source computer to the destination. This tool is widely used by network administrators and engineers to troubleshoot network issues such as high latency, packet loss, and connectivity problems. Traceroute works by sending packets with gradually increasing Time-To-Live (TTL) values to the destination. As each packet reaches a router, the router decrements the TTL value by 1 and discards the packet if the TTL value becomes zero. The traceroute command listens for error messages sent back by the routers ... Read More
