Hi,

I need help on the below Tracert messages from a Windows PC.

Iam confused on the two things below:-

1) Why Two Next Hops are coming for the same IP. (10.8.98.158).
Iam not sure what is that since it is a customer network.

2) Why 10.3.1.40 (last trace) is tracing 4 times. Is it because it is
getting timeouts in the third poll and the fourth time it got it reply?

  6 831 ms 940 ms * 10.3.1.40

  7 892 ms 874 ms * 10.3.1.40

  8 * 914 ms * 10.3.1.40

  9 743 ms * 854 ms 10.3.1.40

Traces are shown below:-
