This is not a critic of this site but all sites, forums and newspapers. Changing DNS is so easy and basic I’m just wondering why it’s not talked about more.\n\nUnless perhaps you run your own DNS server like I do, I am not sure this buys you much privacy. Your previous DNS provider may have been your ISP and now Cloudflare, a company that controls much of the Internet, is logging your DNS requests instead. Even running your own DNS isn’t a silver bullet; after all, DNS requests are sent in cleartext. One thing that it buys you (in some countries) is evasion of ISP-enforced censorship.\n\nInstead, I filter ports 53 and 853, and blacklist the IPs of known public DNS servers. This is intended to prevent devices or programs from circumventing my own DNS with domain blacklists.",
