Network-Tracert command

Tracert
Tracert determines the route taken to a destination by sending ICMP echo packets with varying time-to-live (TTL) values to the destination. Before forwarding a packet, each router along the path is required to decrement the TTL value on a packet by at least 1, so the TTL value is effectively a hop count. When the TTL value on a packet reaches 0, the router sends back an ICMP “Time Exceeded” message to the source computer. Tracert determines the route by sending the first echo packet with a TTL value of 1 and incrementing the TTL value by 1 on each subsequent transmission until the target responds, or the maximum TTL value is reached. The route is determined by examining the ICMP “Time Exceeded” messages sent back by intermediate routers. Some routers silently drop packets with expired TTL values and are invisible to Tracert.
