strange DNS requests


Hi,

I did a fresh install of Debian gnome shell with default settings, but I notice that the system makes daily DNS requests for two domains, Example.com and IPv4only.arpa, the most strange was a DNS application for the domain web.telegram.com, I have no Telegram client installed and I was not using your website so it does not make sense, I want to know if this is normal and common.

"example.com" is likely some default config file that was not set, but whatever that uses it was run. Where are you seeing these requests from? A log file or just sniffing off the wire?
