TTL (Time to Live). This is the hop count of the request, showing the sequential number the router.
Response This shows the IP address of the router, and the time taken (in ms) to respond to each packet
received from the VCS.
*** indicates that the router did not respond to the request.
The route taken between the VCS and a particular host may vary for each Traceroute request.

Tracepath

The Tracepath tool (Maintenance > Tools > Network utilities >
troubleshooting system issues.
It allows you to discover the route taken by a network packet sent from the VCS to a particular destination
host system.
To use this tool:
1. In the Host field, enter the IP address or hostname of the host system to which you want to trace the
route.
2. Click Tracepath.
A new section will appear with a banner stating the results of the trace, and showing the details of each router
along the path, the time taken for each router to respond to the request, and the maximum transmission units
(MTU).
The route taken between the VCS and a particular host may vary for each Tracepath request.

The DNS lookup tool (Maintenance > Tools > Network utilities > DNS
troubleshooting system issues.
