How to verify DNS setting is working?

[wammie]

In Adguard for Android I have chosen a DNS server. However, the Network Info II app for Android shows my DNS server as my usual router address (wifi). How can I be sure that the DNS server chosen in Adguard is being used, for both cellular and wifi connections?

So, I made a discovery using https://dnsleaktest.com. The results from this test list the DNS server I have chosen within Adguard.
