Good information, but are you aware that once in a while Cloudflare DNS goes out of service? This is the current dns I am using on my Router and mobile, some times the dns server will be out of reach and will disturb your internet connection, this can reveal your real network data or mess things up for you if the gambling platform detects that you aren't true with your location, just saying.
Yes, that is the risk. We all know, there is nothing save on the internet even if we use military security ever. For that situation, we need the best DNS provider to reduce that risk. If you ask me, I still don't know the best provider DNS, but google is the best for me, I don't have a problem so far. For some time I use 1.1.1.1. if when I change my browser to firefox, and when I use chrome that is suitable for DNS google.
