What is the MTR command, and how to use it?

By Bob on March 17, 2021

What is the MTR command?

MTR command is a type of traceroute command developed by Matt Kimball in 1997 that allows both traceroute and ping in the same software. Originally the name MTR was an abbreviation of Matt’s traceroute, but in 1998, his colleague Roger Wolff worked on it too and changed the name to My traceroute.

Why is the MTR command better than the traditional Traceroute or Tracert?

The MTR command is better because it combines the Ping and the Traceroute command and gives additional information (statistics about time, packet loss, and round-trip time, too) about each hop on the way from the computer to the host.
