While it’s incredibly convenient to use Google’s 184.108.40.206 DNS server, they log your IP address for 48 hours and analyse usage data, storing some information permanently. As Google is basically an ad agency and collets a lot of information about people using their other services, it’s good to have some alternatives.
Easy instructions on how to change your DNS servers can be found, for example, on Cloudflare’s DNS information page https://220.127.116.11/ (scroll down a bit).
