Tracert command

asked 2019-01-20 17:57:12 +0000

Hello, I'm learning wireshark in a online course. I need help with this command.

I have this trace: https://pastebin.com/7Hn7rzff

1- Is the number of routers 14 because the lane 15 is not a router? I think the lane 15 is the host server.

2- What is the option and minimun value of this option for we do a ping to 12.0.1.28 and we get succesfull result with a path without more routers than the routers of the trace? Is this something about TTL?

Thanks for the help.

Hi,

You are correct. The Time To Live (TTL) field in the Internet Protocol (IP) headers will limit how many hops a packet can do (or how many routers it can traverse) before being dropped.

If you used Wireshark to capture the packets for this trace then you should be able to see each sets of three packets with a TTL increasing from 1 to 15.

This TTL is in the Packet Details pane you need to display the Internet Protocol Version 4 details by clicking on the little triangle to see the value in the header.

Hop 15 is whatever device (server or router) that is using address 12.0.1.28.

If you were told you are tracing to a server than it should be a server.

Cheers,

JF
