What is tracert utility?

The TRACERT diagnostic utility determines the route to a destination by sending Internet Control Message Protocol (ICMP) echo packets to the destination. In these packets, TRACERT uses varying IP Time-To-Live (TTL) values.

What is tracert in simple words?

Traceroute is a command that runs tools used for network diagnostics. These tools trace the paths data packets take from their source to their destinations, allowing administrators to better resolve connectivity issues. On a Windows machine, this command is called tracert; on Linux and Mac, it's called traceroute.

What happens if you do a tracert?

You run a traceroute to a destination device and specify a maximum of 30 hops. Traceroute then does the following: It sends data packets with a TTL of "1" to the destination server. The first network device the data passes through reduces the TTL to "0", and sends back a message that the packets were dropped.

What does traceroute output mean?

A traceroute displays the path that the signal took as it traveled around the Internet to the website. It also displays times which are the response times that occurred at each stop along the route. If there is a connection problem or latency connecting to a site, it will show up in these times.
