Tracepath

tracepath is a tool used to traces path to a network host discovering MTU along this path.
The maximum transmission unit (MTU) is the size of the largest protocol data unit that the layer can pass onwards.
tracepath6 is used for IPv6, it is a replacement of traceroute6
Example : tracepath 127.0.0.1
1: localhost.localdomain 0.528ms reached
Resume: pmtu 65535 hops 1 back 64
You can see the TTL (time to live, is a mechanism that limits the lifespan or lifetime of data in a computer or network.)
With tracepath you can specify some options:
-n : Print primarily IP addresses numerically.
-b : Print both of host names and IP addresses.
-l : Sets the initial packet length (instead 65536 for tracepath and 128000 for tracepath6)

If you have any problem or you need some explanations just write under this post!
