Hi Michael,
for example, one measure ID is this one: 49813750
The result says there are 7 HOPS.
The result of the traceroute made directly on the host is the following one

Since the website is served by cloudflare the route may vary between requests but the are always around 18/20 HOPS
I don’t understand if I0m missing something here. Let me know if you need further details

Hello Roberto,
Would you be able to share screenshots/measurement ids so we can have a look?
Regards,
Michel

I’m doing some measurement from one of my software probes, the measure is a traceroute to a destination.
The results I get are completely different from what I see doing the same traceroute directly on host where the probe is installed. I configured the measure to sue the DNS resolution on the probe..
From the Atlas portal I get a traceroute with 7 hops, doing it directly on the host returns 28 hops, for the same destination.
Why this difference ?
Regards,
Roberto
