The tracert command

This utility determines the route to a destination.

How tracert works

The tracert utility follows several steps:
• 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.
