What utility shows the route that a packet takes to get to its destination?

The utility that shows the route a packet takes to reach its destination is called "traceroute" (or "tracert" on Windows systems). It works by sending a series of packets with incrementally increasing Time to Live (TTL) values, allowing it to identify each hop along the path to the destination. By displaying the IP addresses and response times of each hop, traceroute helps diagnose network issues and understand routing paths.
