I just want to contrast the things that I've said in my previous post.
In fact, you can find many posts on the internet about the performance of 188.8.131.52 DNS. But you can find many sources who talk about the lack of privacy of this platform. I don't have time to explain everything but Google is your best friend to dig further the question (or not when we talk about privacy).
So, I advice to check Quad9 or 184.108.40.206 for better performance and privacy.
