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?

the other DNS resolver can see your IP and the sites you look up if the route to it is not set to go through the VPN. you can maybe use something like traceroute to check that, but it should be possible to conclude it from the routing table.

My device is with always-on VPN and block connections without VPN on too, but I'd like to know if the DNS provider can see my real IP or the IP of VPN provider.
