In regards to PiHole you answered the question yourself later on...it covers “your” network. If your device is mobile then chances are much of the time is spent on other networks and unless you’re going to create a VPN and connect back to your home permanently, your access to PiHole ends as soon as you walk out the door. It’s a great product and I use it myself, but I still have on device filtering for mobile devices for that very reason.Why not just use a PiHole or a service like nextdns.io it covers every device with way more flexibility?
That DNS option you posted looks interesting but it also carries a subscription cost so if this is free then I’m semi inclined to use PiHole at home across the entire network and then some on-device options for my mobile systems. Home desktop, TV, Console etc all can get serviced by PiHole but this or similar covers you on the go.
Again could set up a VPN to home but I’d likely see a huge performance hit in doing so compared to my 4G speeds.
curious how this compares to AdGuard which has some system wide options for various devices.
