DNS ad-blocking & tracker-blocking, DNS over HTTPS (Secure DNS)

Blocking ads and trackers on a look up level is probably the most methodical approach as it means the entire network is protected from known malicious websites/IP’s. Setting up a switch to allow a Raspberry Pi to act as a DNS server is I guess the ultimate home setup, however that obviously requires a switch, Raspberry Pi and a little effort.

The next best thing is to manually set your devices to use DNS over HTTPS which adds some privacy and security to your DNS resolutions, but of course not stopping there and using a DNS provider that adds ad-blocking and tracker-blocking to the mix.

It’s still recommended to use a browser plugin like uBlock Origin and others like LocalCDN, Privacy Badger oh and personally I’d add Cookie AutoDelete, but blocking via DNS is for when you can’t use the former.

First port of call

How-to

For Chromium it’s in the settings, and also if you wish to disable the fall-back it’s “chrome://flags/#dns-over-https” (then search for DnsOverHttpsMode) in the address bar to get to the settings.

Controversy

Secure DNS is a good thing, but centralized is not. Worth reading.
