what is tracert
Tracert is a route tracing utility that display a list of near-side router interfaces of the routers along the path between a source host and a destination. Tracert uses the IP TTL field in ICMP Echo Requests and ICMP Time Exceeded messages to determine the path from a source to a destination through an IP internetwork. Note that some routers silently drop packets with expired TTLs. These routers do not appear in the Tracert display. How Tracert Works
