I caught an app that my daughter’s school uses called ClassDojo that wouldn’t work at my company for some reason. I had to reach out to our security admin and it turns out it was doing DNS lookups by bypassing my company’s DNS server. I submitted a ticket to the company and they ended up either designing the app to fallback to the device’s assigned DNS or either probably doing something else shady. Idk, it works now.
My point is there’s more than one way to do a DNS lookup.
It’s definitely not fool-proof, apparently they can bypass DNS for their connections too. On the other hand, IP block is a thing as well, so maybe it’s a double-edged sword for them.

Yeah that looks suspicious.
