Question.
From what I understand the DNS it's a node from which you PC accesses the internet, right? And your internet provide has a default one that itbhad access to.
How do you know what DNS is ok and what should you look in for a secure DNS?
One other thing what DNS service affects is how quickly webpages loads, especially nowadays when every webpage is full of advertisements. For example, if you try to load a webpage that consists of files on 10 different servers, your computer needs to send 10 DNS queries. If these queries happen sequentially (one query has to resolve, before the next is sent), and if each query takes 1 second, it would take at least 10 seconds for that page to load. If those queries instead resolve in 0.1 second each, that same page would load in about 1 second. GRC Domain Name Speed Benchmark is popular benchmarking tool for testing how fast your DNS service is.
I guess that is not a problem if I usr uBlock, right?
It certainly helps a lot, but webpages often have content from more than one domain. And some ISP provided DNS servers can be slow. Using an ad blocker probably helps more than changing your DNS, but you might still want to make sure your DNS is speedy enough.
