The tracert command

This utility determines the route taken to a destination.
How tracert works
The tracert utility follows several steps to complete its task:
Tracert sends Internet Control Message Protocol (ICMP) echo
packets with varying Time-To-Live (TTL) values to the destination.
Each router along the path must decrement the TTL on a packet by
at least 1 before forwarding it, so the TTL is effectively a hop count.
When the TTL on a packet reaches 0, the router sends back an
ICMP Time Exceeded message to the source system.
Tracert determines the route by sending the first echo packet with a
TTL of 1, and incrementing the TTL by 1 each subsequent
transmission until the target responds or the maximum TTL is
reached.
Tracert then examines the ICMP Time Exceeded messages sent
back by intermediate routers.
