Ask Ubuntu Asked by sd_hito on February 5, 2021
From a fresh reboot I entered netstat -an | more in a terminal shell and located a foreign ip address 99.86.32.24 from netstat’s output connected to my system over port 443. I’ve opted out of sending diagnostic reports to cannonical telemetry servers,
yet I am connected to cannonical and amazon aws, why?
Here’s the output of the whois command with the amazon ip passed as a argument:
NetRange: 99.85.128.0 - 99.87.191.255

My overall question here is why would ubuntu be connected to any other remote server if I have opted out from sending telemetry data? Is there a reason for this/these connections? Or should I be paranoid?
Canonical hosts some content and update mirrors in AWS. That's likely all you're seeing here.

Since you asked, personally, I would be paranoid and block it with iptables and keep and eye out for its re-appearance. And of course be aware if it impacts any service necessary to operating your system. If so, please report it back here. These days, if you're not paranoid, you're crazy.
Use the hint in the notes above to determine what apps are involved to get started in your investigation.
In fact, I found this question while searching for "dogfish routing" because I have found questionable traffic coming from another netblock 54.64.0.0/13 AMAZON-2011L that contains the same string.
