Traceroute is a network tool that allows you to determine the route that data packets take from your computer to a target node (for example, a server). It works by sending a sequence of packets with gradually increasing TTL (Time To Live) values. TTL is a counter that decreases at each intermediate router; when TTL reaches zero, the router sends back an error message (ICMP Time Exceeded).
Thus, traceroute receives responses from each intermediate node along the path, which allows you to see the sequence of routers and the delay time to each of them. This helps identify bottlenecks, failures, or delays in the network.
Example of usage:
traceroute example.com
As a result, you will see a list of IP addresses and response times of each intermediate node on the path to example.com.
