IP Address "leaked" with Secure DNS turned on

I don't think the built-in DNS (Google and Cloudflare) is working. Here is the website I used [https://dnsleaktest.com/]. I ran DNS leak tests only to find out that my IP address, ISP, and my country is still visible. I did not set any DNS in settings, so the leak test did not detect any DNS, even when I set Opera to use Google or Cloudflare.
This issue persists since I started using the Opera browser. The Opera team should kindly fix this

@Chi-oma And why is that an issue?

Secure DNS is to secure (encrypt) the communication between the computer and the DNS server, nothing else.

Chrome and Edge show the same info when you access that page.

If your IP address is leaking even with Secure DNS (DNS over HTTPS or DNS over TLS) enabled, it could be due to WebRTC leaks, improper DNS configuration, or browser settings bypassing secure DNS. WebRTC can expose your local IP address, even with a VPN or Secure DNS, and DNS settings might default to regular servers despite the secure configuration. To prevent this, you should disable WebRTC in your browser, ensure your DNS settings are correctly configured, and use a VPN for extra security. Running DNS leak tests can also help confirm if your setup is secure.

What about for others (in general).

@Chi-oma I don't know, you will need to search. Not every Secure DNS has a page to test it.

Ok. But do you know for these DNS servers and their hostnames:
AdGuard - dns.adguard.com
Quad 9 - dns.quad9.net
Next - dns.nextdns.io

I didn't clearly understand what you said. Also DNS in Opera browser can't be configured at all.
