ELI5: Does a DNS provider or an adversary know my real IP address if I have a DNS leak? (discuss.tchncs.de)

I use a VPN service that is connected to a server in another country, however this VPN service does not offer control over my DNS requests to block some sites so I preferred to use another DNS resolver that has this function.

My question is: When I access my VPN's website, it accuses that a "DNS leak" is occurring. Can the DNS provider know my real IP address, or does it only know my VPN's IP?

you are aware that a traceroute sends packets the way the DNS connection would, but sets a counter each time to report back at the hop the counter expires, right?

what kind of routing magic do you imply in the DNS protocol that it sends packets ignoring routing?

DNS leaks normally occurs when your OS decides to use the wrong interface for DNS queries. It's not magic, sorry.

There is a decent explanation here: https://www.top10vpn.com/what-is-a-vpn/vpn-leaks/

are you a bot? a traceroute to the DNS would show the wrong interface.

Sadly, I can not explain this to you any better.
