I have a question regarding DNS leaks. I connected to a server in Finland using IVPN, and initially, the test indicated no leaks. However, after enabling DNS over HTTPS (DoH) in the Mullvad browser, a subsequent test detected a DNS leak. This leak revealed a UK IP address instead of the expected Finnish one. Should I be concerned about DNS leaks if they only reveal a different IP address?

This seems AI-generated but I will answer in good faith.
It is recommended to use the DNS provided by your VPN provider to blend in with other users of the same VPN. Setting your DNS to Mullvad while using IVPN can make you stand out from other users who use IVPN and the Mullvad browser without changing the DNS server to another provider

Websites can recognize you’re using a different DNS server even if you saw a Finnish IP address, as long as it’s not the same IP as your VPN server.

Hm, I see. It makes me only to stand out from the others.
Why the thumbs down? Did I say something wrong?
I don’t see how this post seems AI generated
Any1 was right =) I used ai to rephrase that question to a more polished one. I’m not a native English speaker

Since you are using Mullvad’s DNS rather than your VPNs, the IP will inevitably be different. The country may also be different depending on where the DNS provider has servers. I would recommended disabling DoH and just using the VPNs DNS when you are connected to avoid standing out from other users.

Default setting in Mullvad is to use their own DNS. In this case its better to use that. In general though, VPN’s dns should be used yes.

Techlore promoted having mismatched DNS and VPN providers just to so people could use some horrid network level filtering.
Don’t do that. DNS is being logged alongside your IPs.

While I agree with everyone else here that its probably best to use your VPNs provided DNS, I do think, especially from the VPN provider, the risk of using a third party DNS is a bit overblown because companies like Proton and Mullvad don’t want a bunch of support issues coming in about third party DNS issues causing problems. As we all know in networking its always DNS 
Proton puts it well
Using custom DNS isn’t unsafe in itself, but we can’t guarantee that it will be as secure as Proton VPN’s DNS service.

Thank you for all your answers. I’ll turn off DNS server then and use the default VPN’s one
