Explanation
Tracert (Traceroute) works by sending packets with progressively higher TTL (Time-to-Live) values, causing them to expire at each router along the path. When TTL expires, the router sends back an ICMP "Time Exceeded" message, which includes the source IP address of that router. This allows Tracert to record the IP addresses of each router on the path to the destination.
