Commands

The Traceroute command is a network tool that helps you see the complete route of a query and identify problematic spots on the networks, such as slow or not responsive routers. You can use it through the Terminal with a simple “traceroute + domain name” command.

It is light, fast, and does the job it was designed for. The great thing is that you can find it on the most popular OSes. 

What is the Traceroute command?

The Traceroute command is a simple software with a CLI interface that serves to show you each hop of a query from your computer to the destination – IP address or domain name. It races the route of a probe and gives back the result. 

The query will travel through the internet, hoping from a router to another and finally reaching the destination. At each of the hops, your computer will send packets and get answers for them. That way, you will get statistics about each of the points, from your device to the destination.

What is MTR command?

MTR comes from Matt’s traceroute. First written by Matt Kimball in 1997 and later updated with Roger Wolff’s help, this is software with CLI that helps you see the route of a query. 

It is based on the traditional traceroute command, but it presents each of the hops on the way, with a table-like view and data like data loss, amount of packets sent, the time of the return of each hop.
